Precautions for maintenance and inspection
The inverter can be replaced with the control circuit wiring kept connected. Before replacement, re-
move the wiring cover of the inverter.
Loosen the two mounting screws at the both side of the control circuit terminal block. (These
screws cannot be removed.) Slide down the control circuit terminal block to remove it.
Be careful not to bend the pins of the inverter's control circuit connector, reinstall the control
circuit terminal block and fix it with the mounting screws.
Before starting inverter replacement, switch power OFF, wait for at least 10 minutes, and then
check the voltage with a tester and such to ensure safety.
