(2) Disconnect the filter power supply cables and place the tester probes on the terminals. The
measured voltage should be 220 Vac or 110 Vac depending on the type of mains electricity
supply.
(3) Disconnect the filter output cables and place the tester probes across the filter terminals. The
measured voltage should be 220 Vac or 110 Vac depending on the type of mains electricity
supply.
This error may be generated even by brief drops in the line voltage due to overloads or
other causes. Therefore, it can be very useful to check the value of the mains voltage
recorded in the inverter memory at the time when the error occurred. To obtain the
mains voltage, the displayed value must be divided by 0.141 .
