Battery Installation Procedure

The EP1100 UPS has a specific battery harness designed for its use. The harness includes a main cabinet
enclosure harness and individual disconnects for each battery. When installing the batteries, please refer to
the manufacturer's instructions for installation and maintenance. The following steps provide installation
and connection of the battery string used with the UPS.
1. The EP1100 system uses a 48VDC battery system. Refer to figure 4-3 when installing the battery
harness for this system. NOTE: Follow diagram as pictured or system damage may occur.
2. Place the batteries on the shelves of the enclosure with the positive terminal facing out. Choice
of cabinet enclosure will dictate exact battery pla0cement. Space the batteries approximately 25-
mm (1 inch) apart to provide adequate airflow.
3. Route the main harness of the battery harness kit along the right side of the cabinet enclosure.
The interconnecting harnesses will be used to connect each individual battery to the main har-
ness.
4. Batteries are wired in series, connecting the negative post of one battery to positive post of the
next. Battery cables and terminals are color coded to aid in correct wiring. Black terminal is nega-
tive (-); red terminal is positive (+).
5. Attach the ring lug to the negative post on the 48VDC battery.
