6-1 CHECK BEFORE AND AFTER «TROUBLESHOOTING»

(A)

Check power supply wiring.

• Check the power supply wires are correctly connected.

(B)

Check power supply.

• Check that voltage is in specified range (±10% of the rating).
• Check that power is being supplied.

• WARNING: If the following troubleshooting must be done with power supplied,
be careful not to touch any uninsulated live part that can cause electric shock

6-2 CIRCUIT BREAKER TRIPS OR FUSE BLOWS.

• When circuit breaker is set to ON, it trips in a few moments. Resetting is not possible.
• Measure insulation resistance. There is a possibility of ground fault.
If resistance value is 1 Mohm or less, insulation is defective.
