FAQs
Below are some Frequently Asked Questions concerning installation of the 1600EP Series UPS.
The batteries for the UPS must be installed while the UPS is energized.
FAQ #1 My Output is ~85V.
Problem: Output is wired across the incorrect output terminals. The voltage across terminals 5 – 6(X2 – N) will
be approximately 85V.
Solution: The correct 120V output terminals are 4 – 6 (X1 – N), and 7 – 6 (X3 – N).
FAQ #2 My Output is other than 85, 120, 208 or 240V in Bypass mode.
Problem: The Terminal strip jumper may be installed incorrectly for the incoming voltage.
Solution: Check that the Jumper wire/buss strip is installed correctly for the incoming voltage.
