Connecting Power Cables
(Refer to section titled Table 4, “Cable Sizes,” on page 12)
5. Connect loads to “Output” terminals.
ATTENTION:
If using separate inputs for Mains and Bypass, it is imperative that the inputs be in phase.
Failure to correctly recognize and adhere to this requirement will cause serious damage to the UPS.
6. Connect mains to the corresponding input terminals. UPS can utilize a single input (using same input
for both Mains and Bypass inputs) or two separate inputs (from same transformer and using same
phases, for separate Mains and Bypass inputs)
- If the UPS is supplied by a single source, connect jumpers from JL1 to BL1 and from JL2 to
BL2. Input is connected to Main Line (ML1 & ML2) terminals. See Figure 8.
- If the bypass input is supplied separately, connect bypass line to the Bypass (BL1 & BL2)
terminals. Input is connected to Main Line (ML1 & ML2) terminals. Do not connect jumpers to
JL1 or JL2. See Figure 8.
7. If UPS is to be operated as single unit connect a jumper between S1 and S2. See Figure 8.
8. If UPS is to be operated as parallel unit ensure that no jumper is connected between S1 and S2.
