Many state, county and city electrical jurisdictions have similar requirements. A UL Field Evaluation is an accepted approach to meet this requirement; UL conducts an unbiased, independent assessment of products at a specific location to essential requirements of applicable product safety standard(s). UL's engineering assessment informs regulating authorities who make product and related installation approval decisions. Please note that the regulating authority for the final installation site provides final approval of this equipment and the installation. This project's purpose was to evaluate a product that was not Listed or otherwise certified by a testing laboratory recognized by the authority having jurisdiction. Products undergoing this evaluation process do not acquire a UL Listing, UL Recognition, or UL Classification. UL has not established factory Follow -Up Services to determine the conformance of any subsequently produced, relocated, or otherwise altered product(s) or system(s). Installation model codes are referenced in this document where necessary to ensure the product can be properly installed according to the code (e.g. National Electrical Code, NFPA 70). At the request of Mr. Gary VanNice of Technical Services For Electronics Inc, a Field Evaluation project was initiated. A Preliminary evaluation was completed at: • Technical Services for Electronics Inc, 10565 Southwest Nimbus Avenue, Tigard, Oregon. The results of the preliminary evaluation identified items that do not comply with applicable standard(s) and require corrective action as detailed in this report. When these discrepancies are corrected, a final inspection is required to verify that changes have rendered the equipment compliant and complete the Field Evaluation. 2 Conditions of Acceptability Except where otherwise stated in the product description and evaluation sections of this report, this evaluation and the application of the Field Evaluated Product Mark is subject to the following Conditions of Acceptability. 2.1 Except for like- for -like component replacement in the event of component failure, no change or addition to the product or system shall be made that would alter its construction, operation, function, layout, source of supply, physical location or operating environment. If such changes or additions to the product occur, the Field Evaluated Product Mark shall be considered invalid, and a separate evaluation shall be required to determine compliance with applicable product safety standards under the changed conditions. 2.2 The completed evaluation and application of the UL Field Evaluated Product Mark by UL does not assume liability on the part of UL and does not relieve the manufacturer, installer, user, or other relevant parties of their responsibilities. The product evaluation is based on adherence to sound engineering practices, and compliance with the applicable product safety standards and installation code. 2011 - 3717 -FE Field Evaluation Services Report Page 3 of 20 2.3 This evaluation considered the risks associated with electric shock, fire, and casualty hazards as specified in the evaluation section of the report only. No other hazards were evaluated during this evaluation. 2.4 Unless otherwise stated in the product description, this product was evaluated for installation in an indoor, dry, normal environment only. The product was not evaluated for installation in any hazardous classified location as defined in the latest edition National Electrical Code as adopted by the National Fire Protection Association. The product was not evaluated for installation in an environment subject to rainfall, water spray, steam, or exposure to any corrosive chemicals that deteriorate the enclosure or components. 2.5 The UL Field Evaluated Product Mark shall not be considered as equivalent to the UL Listing Mark, UL Recognized Component Mark, or UL Classified Product Mark. The UL Field Evaluated Product Mark indicates compliance with the applicable parts of the Standards referenced in Section 3 at the time the Mark was applied, and considering only the final installation site. The applicable parts included in the evaluation are the construction review, markings, and those testing protocols that are non - destructive. 3 Referenced Standards • NFPA 70, National Electrical Code, 1st Edition, Revised 10/19/2011 • NFPA 79, Electrical Standard For Industrial Machinery, 1st Edition • UL 508A, Standard For Industrial Control Panels, 1st Edition, Revised 02/04/2010 • UL Subject 2011, Outline of Investigation for Factory Automation Equipment, 2nd edition, 12/27/06 4 Product Description Equipment Name: Double Twisted Bunching Pitch Machine HST -200P — { .,. 4 a'' •' Machine front view Machine back view Description: This evaluation was for a Double Twist Bunching Pitch machine.

Many state, county and city electrical jurisdictions have similar requirements. A UL Field Evaluation is an accepted approach to meet this requirement; UL conducts an unbiased, independent assessment of products at a specific location to essential requirements of applicable product safety standard(s). UL's engineering assessment informs regulating authorities who make product and related installation approval decisions. Please note that the regulating authority for the final installation site provides final approval of this equipment and the installation. This project's purpose was to evaluate a product that was not Listed or otherwise certified by a testing laboratory recognized by the authority having jurisdiction. Products undergoing this evaluation process do not acquire a UL Listing, UL Recognition, or UL Classification. UL has not established factory Follow -Up Services to determine the conformance of any subsequently produced, relocated, or otherwise altered product(s) or system(s). Installation model codes are referenced in this document where necessary to ensure the product can be properly installed according to the code (e.g. National Electrical Code, NFPA 70). At the request of Mr. Gary VanNice of Technical Services For Electronics Inc, a Field Evaluation project was initiated. A Preliminary evaluation was completed at: • Technical Services for Electronics Inc, 10565 Southwest Nimbus Avenue, Tigard, Oregon. The results of the preliminary evaluation identified items that do not comply with applicable standard(s) and require corrective action as detailed in this report. When these discrepancies are corrected, a final inspection is required to verify that changes have rendered the equipment compliant and complete the Field Evaluation. 2 Conditions of Acceptability Except where otherwise stated in the product description and evaluation sections of this report, this evaluation and the application of the Field Evaluated Product Mark is subject to the following Conditions of Acceptability. 2.1 Except for like- for -like component replacement in the event of component failure, no change or addition to the product or system shall be made that would alter its construction, operation, function, layout, source of supply, physical location or operating environment. If such changes or additions to the product occur, the Field Evaluated Product Mark shall be considered invalid, and a separate evaluation shall be required to determine compliance with applicable product safety standards under the changed conditions. 2.2 The completed evaluation and application of the UL Field Evaluated Product Mark by UL does not assume liability on the part of UL and does not relieve the manufacturer, installer, user, or other relevant parties of their responsibilities.

Many state, county and city electrical jurisdictions have similar requirements. A UL Field Evaluation is an accepted approach to meet this requirement; UL conducts an unbiased, independent assessment of products at a specific location to essential requirements of applicable product safety standard(s). UL's engineering assessment informs regulating authorities who make product and related installation approval decisions. Please note that the regulating authority for the final installation site provides final approval of this equipment and the installation. This project's purpose was to evaluate a product that was not Listed or otherwise certified by a testing laboratory recognized by the authority having jurisdiction. Products undergoing this evaluation process do not acquire a UL Listing, UL Recognition, or UL Classification. UL has not established factory Follow -Up Services to determine the conformance of any subsequently produced, relocated, or otherwise altered product(s) or system(s). Installation model codes are referenced in this document where necessary to ensure the product can be properly installed according to the code (e.g. National Electrical Code, NFPA 70). At the request of Mr. Gary VanNice of Technical Services For Electronics Inc, a Field Evaluation project was initiated. A Preliminary evaluation was completed at: • Technical Services for Electronics Inc, 10565 Southwest Nimbus Avenue, Tigard, Oregon. The results of the preliminary evaluation identified items that do not comply with applicable standard(s) and require corrective action as detailed in this report. When these discrepancies are corrected, a final inspection is required to verify that changes have rendered the equipment compliant and complete the Field Evaluation. 2 Conditions of Acceptability Except where otherwise stated in the product description and evaluation sections of this report, this evaluation and the application of the Field Evaluated Product Mark is subject to the following Conditions of Acceptability. 2.1 Except for like- for -like component replacement in the event of component failure, no change or addition to the product or system shall be made that would alter its construction, operation, function, layout, source of supply, physical location or operating environment. If such changes or additions to the product occur, the Field Evaluated Product Mark shall be considered invalid, and a separate evaluation shall be required to determine compliance with applicable product safety standards under the changed conditions. 2.2 The completed evaluation and application of the UL Field Evaluated Product Mark by UL does not assume liability on the part of UL and does not relieve the manufacturer, installer, user, or other relevant parties of their responsibilities. The product evaluation is based on adherence to sound engineering practices, and compliance with the applicable product safety standards and installation code. 2011 - 3717 -FE Field Evaluation Services Report Page 3 of 17 2.3 This evaluation considered the risks associated with electric shock, fire, and casualty hazards as specified in the evaluation section of the report only.

Many state, county and city electrical jurisdictions have similar requirements. A UL Field Evaluation is an accepted approach to meet this requirement; UL conducts an unbiased, independent assessment of products at a specific location to essential requirements of applicable product safety standard(s). UL's engineering assessment informs regulating authorities who make product and related installation approval decisions. Please note that the regulating authority for the final installation site provides final approval of this equipment and the installation. This project's purpose was to evaluate a product that was not Listed or otherwise certified by a testing laboratory recognized by the authority having jurisdiction. Products undergoing this evaluation process do not acquire a UL Listing, UL Recognition, or UL Classification. UL has not established factory Follow -Up Services to determine the conformance of any subsequently produced, relocated, or otherwise altered product(s) or system(s). Installation model codes are referenced in this document where necessary to ensure the product can be properly installed according to the code (e.g. National Electrical Code, NFPA 70). At the request of Mr. Gary VanNice of Technical Services for Electronics Inc., a Field Evaluation project was initiated.
