5.1.3 Connection of Power Cables for Dual input Unit
Connect the input, output and battery cables to the terminals as shown in the figure below:
MASTER HP - UL 300 kVA Power connection Terminals
MASTER HP - UL 400 kVA and 500 kVA Power connection Terminals
Remove the jumpers present between the SWIN and SWBY.
The input phase connections attach using bolts through the holes that were previously used to attach the bus bars.
The main (rectifier) input is located on the left and the bypass input is on the right. The neutral input comes
from the bypass source; no neutral is to run from the rectifier input source, although the rectifier source must be
a grounded wye.
Note: Maintenance Bypass Switch optional.
Bond: The UPS is provided with a separate bus bar that connects the Neutral Output to the frame Ground for
delta input connection. This is required to meet NEC grounding code for separately derived neutrals. When a
Neutral is provided in a Wye configured input connection the bus bar must be removed.
Once installation has been completed inside the equipment, replace the switch cover panel and close the door.
