INSTRUCTION FOR INSULATION RESISTANCE MEASUREMENT.

It is recommended to measure the insulation resistance at least every 2 years, and also after each repair of

the machine.

The insulation resistance measured with 500V megaohm meter should not be lower than:

- 5,0 MOm between input circuit (mains plug L1, L2 or L3) and output circuit (output terminal XB1 (+))

- 2,5 MOm between input circuit (mains plug L1, L2 or L3) and control circuit (terminal X1 for connecting wire

feeder)

- 2,5 MOm between input circuit (mains plug L1, L2 or L3) and housing (grounding pin)

- 2,5 MOm between output circuit (output terminal XB1 (+)) and housing (grounding pin)

- 2,5 MOm between control circuit (terminal X1 for connecting wire feeder) and housing (grounding pin).

To perform the measurement:

Mains power switch Q1 must be set to position I (ON), contacts of contactor K1 must be shorted, shorten

contacts of terminal X2 on LA07 board, switch Q2 must be set to position I (ON), shorten “+” and “-“ output

terminals, shorten contacts of terminal X1.

After the measurement the machine must be returned to its initial status.
