8. If the UPS does not have an attached Power Distribution Unit (PDU), wire the output of the UPS to
appropriate load as follows:
Wire 208 V load between terminals marked 120A (x1) and 88B (x3).
Wire 120 V loads between terminals marked 0 (x2) and 120A (x1) or 0 (x2) and 120B (x4).
CAUTION:
The load connected to 120A and 120B must each be no more than 1/2 the nameplate rated 120 V current.
User must properly fuse these outputs to this rating.
9. Connect the UPS to the battery cabinet(s) (if required)
See Table 2, “Minimum Requirements for Sinergy Series UPS Installation,” on page 15 for minimum
wire gage, wire temperature and screw torque requirements.
For model SE61 (if using an external battery cabinet), first remove the connection plate from the rear
of the battery cabinet, then connect the battery cable (supplied with the battery cabinet) from the
battery connector on the UPS to the terminals on the battery cabinet. Confirm that (+), (-) and GND
terminals are connected to proper wires. Connect any additional battery cabinets in a “daisy-chain”
manner until all GND terminals, (-) terminals and (+) terminals are connected together. See Table 2,
“Minimum Requirements for Sinergy Series UPS Installation,” on page 15 for minimum wire gage,
wire temperature and screw torque requirements.
For models SE101 and SE203, first remove the connection plate from the rear of the battery cabinet.
Next, connect the wires from GND terminal on the UPS to GND wire on the battery cabinet, and then
from (-) terminal on the UPS to the (-) terminal on the battery cabinet. Finally, connect (+) terminal
on the UPS to the (+) terminal on the battery cabinet. Connect any additional battery cabinets in a
“daisy-chain” manner until all GND terminals, (-) terminals and (+) terminals are connected together.
See Table 2, “Minimum Requirements for Sinergy Series UPS Installation,” on page 15 for minimum
wire gage, wire temperature and screw torque requirements.
10. Carefully replace the connection plate(s) on the battery cabinet and the UPS, making sure that no wires
are pinched or damaged.
11. Confirm that all input and output breakers on the UPS and battery cabinet(s) are in the OFF position.
12. Restore power source to the UPS.
WARNING:
Make sure that all circuit breakers on the battery cabinet and UPS are in the“OFF”
postion before removing any covers.
