12 UL Standards
74 YASKAWA TOEPC71061737B GA800 Drive Installation & Primary Operation
The UL/cUL Mark indicates that this product satisfies stringent safety standards. This mark appears on products in the
United States and Canada. It shows UL approval, indicating that it has been determined that the product complies
with safety standards after undergoing strict inspection and assessment. UL-approved parts must be used for all major
components that are built into electrical appliances that obtain UL approval.
This product has been tested in accordance with UL standard UL 508C, and has been verified to be in compliance
with UL standards.
Machines and devices integrated with this product must satisfy the following conditions for compliance with UL
standards.
◆ Area of Use
Install this product in a location with Overvoltage Category III and pollution degree 2 or less as specified in UL 508C.
■ Ambient Temperature Setting
Maintain the ambient temperature within the following ranges according to the enclosure type.
• IP20/UL Type 1: -10 °C to +40 °C (14 °F to 104 °F)
• IP20/UL Open Type/Heatsink External Mounting: -10 °C to +50 °C (14 °F to 122 °F)
• IP55/UL Type 12 Heatsink External Mounting; front side: -10°C to +50 °C (14 °F to 122 °F)
• IP55/UL Type 12 Heatsink External Mounting; back side: -10°C to +40 °C (14 °F to 104 °F)
◆ Main Circuit Wire Gauges and Tightening Torques
Refer to Three-Phase 200 V Class on page 31 and Three-Phase 400 V Class on page 35 for the recommended wire
gauges and tightening torques of the main circuit terminals.
Comply with local standards for correct wire gauges in the region where the drive is used.
WARNING
Electrical Shock Hazard. Only connect peripheral options, for example a DC link choke or braking resistor, to
terminals +1, +2, +3, -, B1, and B2. Incorrect wiring can cause serious injury or death.
Note:
• The recommended wire gauges are based on drive continuous current ratings with 75 °C (167 °F) 600 V class 2 heat-resistant indoor PVC
wire. Assume these conditions:
–Ambient temperature: 40 °C (104 °F) or lower
–Wiring distance: 100 m (328 ft) or shorter
–Normal Duty Rated current value
• Refer to the instruction manual for each device for recommended wire gauges to connect peripheral devices or options to terminals +1, +2,
+3, -, B1, and B2. Contact Yaskawa or your nearest sales representative if the recommended wire gauges for the peripheral devices or
options are out of the range of the applicable gauges for the drive.
• 2257 to 2415 and 4208 to 4720, use UL-approved closed-loop crimp terminals on the drive main circuit terminals. Use the tools recommend
by the terminal manufacturer and make sure that the terminals are correctly connected.
◆ Closed-Loop Crimp Terminals
To comply with UL standards on drive models 2257 to 2415 and 4208 to 4720, use UL Listed closed-loop crimp
terminals and heat-shrinkable tubing. Use the tools recommend by the terminal manufacturer to crimp the closed-loop
crimp terminal. Yaskawa recommends closed-loop crimp terminals and heat-shrinkable tubing from PANDUIT Corp.
Comply with local standards for correct wire gauges in the region where the drive is used.
Use the tools recommended by PANDUIT Corp. to crimp the closed-loop terminals.
Refer to Table 12.1 to select crimp terminals as specified by drive model and wire gauge.
Note:
To comply with UL standards, use only insulated crimp terminals or crimp terminals with insulation tubing. Use UL Listed vinyl-coated
insulated copper wires for operation with a continuous maximum permitted temperature of 75 °C at 600 V.
