3.1 Turning the UPS On and Off
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, “Operating the UPS,” “Sense Type”).
In generator mode, the range of acceptable input frequency and voltage is expanded to
accept the uctuations created by a generator .
3.1.1 Turn On
This procedure assumes the line is qualied and the batteries are fully charged. If the UPS
does not act as described, troubleshoot as described in Section 3.6, “Troubleshooting.”
If this is the rst turn on after the UPS’s installation or maintenance, do steps 3 and 4, or do
a battery test (See Section 3.4 “Operating the UPS,” “Battery Test”) to conrm the wiring is
correct, that the batteries are charged and that the UPS functions correctly.
Before starting, make sure the UPS’s battery and input circuit breakers are off.
Procedure
1. Turn on the battery circuit breaker.
For Model 1000, the LCD displays STANDBY. For Models 300 and 600, ensure the LEDs
operate (See Figure 3.1).
2. Turn on the input circuit breaker.
Note: The Novus Micro series has auto-frequen-
cy sensing. When it is rst turned on, it senses
the line frequency and adjusts its output fre-
quency to match.
The LCD displays RETRAN, then shows LINE,
or BUCK or BOOST. The status LED turns on.
If there is no line power, the UPS will go to Line
mode when the line is qualied. If you need to
provide backup battery power to the load, do a
manual start by using the inverter command (See
Section 3.4 “Operating the UPS,” “Inverter”).
3. Turn off the input circuit breaker.
The LCD shows INVERTER, the status LED
starts ashing to show the UPS is running on
backup battery power.
