400 Startup
The UPS can be started once the AC wiring has been installed (as well as any optional battery cabinets or
switches). Make sure you adjust the voltage selection switch (Section 306) if necessary before starting the UPS.
1. For B610010K models, turn on the battery breaker on the back panel of the UPS. (See the labeling on the
back of the UPS, or see the drawings in Section 200.)
2. Turn on the input breaker on the UPS’ back panel. The fans will begin to rotate, and the Line and Bypass
LEDs will come on (see page 5). At this point, the UPS will begin charging the batteries. To get the most
amount of battery backup time, you should let the batteries fully charge before completely starting the
UPS. Charging takes about 10 hours.
3. If your unit has an optional Maintenance Bypass Switch, turn the switch to “UPS.”
4. Press the
button on the front of the UPS for at least one second to turn the UPS on.
All of the “% load” LEDs on the front panel will light at first, then they will light one by one. After a few
seconds, the Inverter LED will light to show that the inverter has been started; at the same time, the Bypass
LED will be off. The UPS is now in normal mode. If the Line LED flashes and the Battery LED is on at
the same time, your AC input source’s voltage and/or frequency are outside of the specifications for
the UPS. For this reason, the UPS is running on battery power.
5. Turn on the output breaker on the UPS’ back panel. This turns on output power to the equipment connected
to the UPS.
During a power failure or a severe
power problem, the UPS will use
its batteries and inverter to
continue delivering output to your
equipment. When this happens,
the Battery LED will be on, the
Line LED will be off, and the
UPS will sound an alarm every 4
seconds. To silence the alarm,
press the
button.
6. Start the equipment connected to
the UPS. If the equipment
overloads the UPS, the UPS
will sound an alarm (see Section
504). Remove noncritical
equipment from the UPS and
recheck the load level.
CAUTION
To avoid possible equipment damage or personal injury, assume that the UPS terminals have AC
voltage present whenever AC input voltage or DC battery voltage is applied. The UPS can provide
output voltage from its batteries even when there is no AC input voltage. When AC input voltage is
available, the UPS can provide output voltage even when its batteries are disconnected. To make sure
there will be no UPS output voltage, always disconnect the AC input source, shut off the UPS output
breaker, and shut off the UPS battery breaker (or disconnect/shut off the DC voltage source). For units
with bypass switches, make sure the switch is turned to “Bypass” or “Off.”
