4-6-23 Life time Warning Output Function

4-6-24 Starting Contact Signal

Capacitor life warning signal – The inverter checks the operating life of the
capacitors on the internal circuit board on the basis of the internal tempera-
ture and cumulative power on time. You can also monitor the state of the
capacitor life warning signal (WAC) in
recommended to replace the main PCB and control PCB.
Cooling fan warning signal – If the signal is given out, check the cooling fan
cover for clogging. You can also monitor the state of WAF signal in
