circuit terminals.
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

Main Circuit Terminal Block Wiring Procedure
DANGER
Electrical Shock Hazard. Do not examine, connect, or disconnect wiring on an energized drive. Before servicing,
disconnect all power to the equipment and wait for the time specified on the warning label at a minimum. The internal capacitor
stays charged after the drive is de-energized. The charge indicator LED extinguishes when the DC bus voltage decreases below 50
Vdc. When all indicators are OFF, remove the covers before measuring for dangerous voltages to make sure that the drive is safe. If
you do work on the drive when it is energized, it will cause serious injury or death from electrical shock.
The procedures to wire the main circuit terminal block are different for different drive models. Refer to
procedures by drive model.
