***CAPACITOR PRE-CHARGE INSTRUCTIONS***
WARNING: READ INSTRUCTIONS BEFORE CONNECTING BATTERY
To prevent the DC output fuse from blowing when connecting the battery,
connections to the power supply and batteries should be done in the
following order (single power supply).
Connect AC input line to the terminal block provided. Be sure the units
’
AC circuit breaker is off.
Observe the polarity of the battery cables, charger output, and relay rack terminals. Connect the
proper battery cable to the ground bar or battery charger output terminal.
Energize the power supply by turning on the units' AC breaker. This will charge the capacitors inside
the power supply and eliminate heavy arcing when the remaining battery cable is connected. After
approximately one (1) minute, turn off the power supply and immediately connect the remaining
battery cable.
Connect loads.
Turn on the power supply again and the charger will commence charging the batteries and powering
the load. (NOTE: For units equipped with a low-voltage disconnect panel, the "Load On" switch
must be put in the "Load On" position.)
