Extended Battery Pack Installation
CAUTION: Extended Battery Pack (EBP) Installation should be performed by qualified service
personnel.
1.
Verify that the DC circuit breaker on the rear panel of the EBP is in the OFF position.
2.
Turn the UPS OFF and disconnect the UPS Input Cord from the AC wall outlet.
3.
Remove the EBP connector cover from the UPS rear panel.
4.
Connect the external DC battery cable from the EBP to the appropriate connector on the UPS.
5.
Secure the DC battery cable to both the rear of the UPS and the rear of the EBP by using M3 x 8
screws provided (2 each per connector end).
6.
Repeat the above procedure for testing and securing each additional EBP required.
CAUTION: Do not use extension cords when connecting input AC power to UPS or EBP’s
7.
Move the DC circuit breaker on the rear of each EBP to the ON position. At this point the UPS

If the EBP’s are plugged into an AC source and properly installed, the internal batteries will be
charged when acceptable voltage is present. EBP’s must be charged for a minimum of 6 hours
for full battery time.
NOTE: If the EBP is going to be out of service or stored for six months or longer, the
batteries must be recharged for at least 36 hours every six months.
Extended Battery Pack Q & A
1.
Which EBP’s do I connect to an AC input source?
•
It is possible to plug in every EBP into an AC input source. The more connected the
faster the recharge time. It is recommended that every third EBP be connected to
incoming AC utility to properly charge the batteries in a complete system. Leaving too
many chargers connected may cause an over charge situation which could damage the
batteries.
2.
Which LED’s are supposed to be lit on the front of each EBP?
