2.4 Connecting the External Battery Pack
DANGER:
There are hazardous voltages inside the battery packs. Use extreme cau-
tion. For more information on battery handling, see the safety instructions in the front of
this manual.
CAUTION:
1)
Verify the pack’s polarity and voltage at the connector before attaching the cable to
the unit.
2)
When a pack or batteries have been in storage for more than 6 months, they should
be recharged for at least 24 hours and then tested with a load before installation. If after
charging, a battery’s voltage varies more than 0.3 VDC from the others, do not use it.
Tools and Materials Required:
•
DC voltmeter.
•
Phillips screwdriver.
Procedure:
1
Verify the battery circuit breaker is switched off. Keep it off until after the unit has been
started with line power.
For the CFR 5000, loosen the cover plate and slide it up to expose the connector (Figure
3
Verify the correct DC voltage and polarity at the battery pack’s connector. It should be
between 48 to 53 VDC.
TIP:
Wrong voltages or polarities could damage the unit or the battery pack.
Connect the pack’s ground wire to the unit’s ground connection (Figures 2.5 and 2.6).
Connect the pack’s connector to the unit’s battery connector (Figures 2.5 and 2.6).
