Wiring the UPS
Before connecting the UPS, read the siting considerations above and check you have selected breakers
and cables with the correct ratings.
WARNING!
BEFORE ATTEMPTING TO WIRE THE UPS ENSURE ALL BREAKERS ARE IN THE OFF
POSITION AND WHERE POSSIBLE LOCKED OFF.
Caution:
DO NOT mix batteries from different manufacturers or mix different types of
batteries. DO NOT use old and new batteries together.
Caution:
Ensure correct phase rotation in the 3-phase wiring.
To connect the UPS to your system:
1. Unlock and open the front door of the UPS.
2. Check the external battery as follows:
a. Ensure that the number of 12 V blocks in each string (positive and negative) is equal and matches
the number specified in your order.
b. Remove the cover plate below the black start switch and check that the correct combination of
battery jumpers is fitted for the number of batteries in the system.

c. Measure the battery voltage in each string, which should be approximately 192 Vd.c. for 16
batteries, 204 Vd.c. for 17 batteries, 216 Vd.c. for 18 batteries, 228 Vd.c. for 19 batteries and 240
Vd.c. for 20 batteries.
3. Remove the lower cover to gain access to the breakers and terminals.
4. Feed all cables through the bottom of the unit, moving the securing plate as needed. If the unit is part
of a parallel system, fit the parallel cables before the main power cables.
Caution:
Where terminal blocks are not available for connections, fit ring crimps to the
ends of cables. This is the case for the E480 battery cables.
