Grounding for inverter and motor
Description
Connect the 3-phase input power lines.
Connect a 3-phase motor
For a backup of the control circuit power supply, connect AC power
lines same as that of the main power input.
Connect a DC reactor (DCR) for improving power factor (an option
for the inverter whose capacity is 55 kW or below).
Connect a DC link bus of other inverter(s). An optional regenerative
converter is also connectable to these terminals.
Normally, no need to use these terminals. Use these terminals for an
auxiliary power input of the fans in a power system using a power
regenerative PWM converter (RHC series).
Grounding terminals for the inverter's chassis (or case) and motor.
Earth one of the terminals and connect the grounding terminal of the
motor. Inverters provide a pair of grounding terminals that function
equivalently.
* Perform wiring as necessary
