4.2 Troubleshooting
Procedure
Troubleshooting should be performed only by trained service personnel or experienced electricians. Before
setting up any complicated testing or making any conclusions, inspect the charger using the guide below.
Check the following:
1.
Check DC output cables, connections, battery type, and number of cells against the charger’s rating.
2.
Check charger specifications against customer order.
3.
Check input connections, input voltage, and breaker size.
4.
Check for shipping damage, loose connections, broken wires, etc.
5.
Certain failures can be caused by defective batteries and customer loads; make sure batteries and loads are
free from defects.
NOTE: If the problem is found to be located in the printed circuit boards, the board should be replaced. No
attempt should be made to repair circuit boards in the field.
