D.3 UL and CSA Standardsu UL Standards ComplianceThe UL/cUL mark applies to products in the United States and Canada. It indicates that UL has performed product testing andevaluation, and determined that their stringent standards for product safety have been met. For a product to receive ULcertification, all components inside that product must also receive UL certification.Figure D.3 UL/cUL MarkThis drive is tested in accordance with UL standard UL508C and complies with UL requirements. The conditions describedbelow must be met to maintain compliance when using this drive in combination with other equipment:n Installation AreaDo not install the drive to an area greater than pollution degree 2 (UL standard).n Ambient TemperatureIP00/Open Type Enclosure: -10 °C to +50 °C (14 °F to 122 °F)IP20/UL Type 1 Enclosure: -10 to +40 °C (14 °F to 104 °F)Finless Type: IP20/IP00 Enclosure: -10 to +45 °C (14 °F to 113 °F)n Main Circuit Terminal WiringYaskawa recommends using closed-loop crimp terminals on all drive models. To maintain UL/cUL approval, UL Listedclosed-loop crimp terminals are specifically required when wiring the drive main circuit terminals on models 5A0041 to5A0242. Use only the tools recommended by the terminal manufacturer for crimping. Refer to Closed-Loop Crimp TerminalRecommendations on page 355 for closed-loop crimp terminal recommendations.Note: The mark indicates the terminals for protective ground connection as defined in IEC/EN 60417-5019.Grounding impedance: 600 V: 10 Ω or lessWire Gauges and Tightening TorquesThe wire gauges listed in the following tables are Yaskawa recommendations. Refer to local codes for proper wire gaugeselections.Table D.2 Wire Gauge and Torque Specifications (Three-Phase 600 V Class)Drive Model Terminal Recomm.
