Operation
If the UPS constantly switches between Inverter and Line modes due to a noisy line, the
UPS’s input parameters should be broadened from normal to generator (See Section
3.4, “Programming the UPS,” “Sense Type”).
In generator mode, the range of acceptable input frequency and voltage is expanded to
accept the fluctuations created by a generator.
3.2.1 Turn On
This procedure assumes the line is qualified and the batteries are fully charged. If the UPS
does not act as described, do troubleshooting as described in Section 3.6, “Troubleshooting.”
If this is the first turn on after the UPS’s installation or maintenance, do steps 3 and 4, or do a
battery test (
See
Section 3.4 “Programming the UPS,” “Battery Test”) to confirm the wiring is
correct, that the batteries are charged and that the UPS functions correctly.
Before starting, turn off the UPS’s battery and input circuit breakers.
Procedure
1. Turn on the battery circuit breaker.

2. Turn on the input circuit breaker.
The FXM series has autofrequency
sensing. When it is first turned on, it
senses the line frequency and adjusts
its output frequency to match.

If there is no line power, the UPS will go
to Line mode when the line is qualified.
If you need to provide backup battery
power to the load, do a manual start by
using the inverter command (
See
Section
3.4 “Programming the UPS,” “Inverter”).
