Starting the UPS System
Once the modules have been connected as shown in the preceding
section (UPS Connections, page 10) the UPS system is ready to be
started. There are two ways to start the system: from AC input
power (if present) or from batteries. If not already done, switch the
input breaker on (figure 1, page 9). If the “AC Input” LED is lit,
proceed on to “Starting when AC power is available”. If the LED is
not lit, there is no AC power available. If the unit is to be started
when AC power is not available proceed to “Starting on DC power.”
Starting When AC Power is Available
If the system is being started with AC input power the system is
started by switching the RUN/STOP switch to the RUN position
(RUN = I, STOP = 0). When the RUN/STOP switch is in the RUN
position both the “AC Input” and the “On Line” LEDs should be lit.
When the unit is started with AC input power it is advisable to al low
time for the batteries to fully charge before any load is connected
(see “Battery Recharge Time”, page 15).
