Jumper Settings for the Optional Battery Charger

Jumper Location

SEALED:
• JUMPER ON - If you are installing sealed batteries, the jumper remains across
this pair of pins. This selection sets the charge rate to 14.3 Vdc in the Bulk stage
and 13.6 Vdc in the float stage.
• JUMPER OFF - For vented batteries, remove the jumper across these pins to set
the charge rate to 14.7 Vdc and 13.3 Vdc respectively.
DEEP:
• JUMPER ON - This pair of pins controls the amount of allowable battery
discharge. When the jumper connects these two pins, the inverter will allow the
batteries to discharge until completely drained.
• JUMPER OFF - When not installed, the inverter will not allow the batteries to be
discharged below 11.8 Vdc for more than five minutes.
UPS:
• JUMPER ON - This pair of pins controls the sensitivity of the charger to
variations in voltage from the AC source. When a jumper connects these two
pins, the charger will stop charging and the inverter will provide AC power
within 35 milliseconds or less of an AC voltage drop to below 85-90 volts.
• JUMPER OFF - With the jumper removed, the shift from charger to inverter will
be delayed at least 200 milliseconds to allow AC voltage to return to normal. If
AC voltage does return to normal within this period, the charger will disengage
and the inverter (when turned on) will provide AC power from the batteries.
This prevents the charger from disengaging unnecessarily due to poor quality
voltage. For generator charging, do not connect these pins.
