SERVOPACK Main Circuit Wires
This section describes the main circuit wires for SERVOPACKs.
Note: To use 600-V heat-resistant polyvinyl chloride-insulated wire (HIV), use the following table as reference for the appli-
cable wires.
•
The specified wire sizes are for three bundled leads when the rated current is applied with a surrounding air
temperature of 40°C.
•
Select the wires according to the surrounding air temperature.
Three-phase, 200-VAC Wires for

-7S SERVOPACKs
These specifications are based on IEC/EN 61800-5-1, UL 61800-5-1, and CSA C22.2 No.274.
1. To comply with UL standards, use UL-compliant wires.
2. Use copper wires with a rated temperature of 75° or higher.
3. Use copper wires with a rated withstand voltage of 300 V or higher.
