8. Maintenance
To avoid initiating this fault, make sure to follow and include the next steps:
• Use authorized batteries
• Do not exceed the lengths of the cable (see appendix)
• Ensure proper connections.
Connect the battery wires to the terminal strip, but do not connect the battery terminals yet.
When all electrical connections are made (mains, loads and batteries):
1. Close the upstream mains circuit-breaker.
2. Check the load output voltage – when OK – turn the battery charger OFF again
3. Connect the battery terminals – turn on the battery charger again.
Your battery charger is operating correctly when all 3 LEDs on the front of the PSE are green.
If not, refer to the Trouble shooting section at the end of this manual.
The battery presence test is performed every 30 seconds for the first 20 minutes after
commissioning and every 15 minutes afterwards. As soon as a fault is detected, this test is
performed every 30 seconds until 20 minutes after the fault is disappeared/solved.
The impedance measurement test occurs every 4 hours when AC mains is present and when the
total output current is < 12A. The impedance limit value is 26mΩ ±10% at 48 V (jumper at '75') or
40 mΩ ±10% at 48 V (jumper set at '50').
A battery voltage compensation system maintains the charge characteristics within the limits
specified by the battery manufacturer across the entire operational temperature range. This
requires the temperature sensor to be installed.
•
The battery low voltage protection threshold is 43.2 V ±3 %.
•
The element causing the cut-out will be in the + position.
•
During start-up: the battery relays will not close when batteries are reversely connected
•
During operation: fuse F8 will blow when batteries are reversely connected
Only to be done by authorized and qualified personnel!
