4.1 Start-up, Test and Shutdown,
continued
Switching OFF the UPS:
1. Switch all equipment connected to the UPS OFF.
2. Switch the rear panel “BATTERY” circuit breaker revent the UPS from initiating
LINE FAILURE operation when AC Power is removed.
3. Unplug the CFR's AC power cord from the wall receptacle.

“OUTPUT PARAMETERS” provides UPS Output Voltage, Current, Volt
Amps, Power in Watts, Power Factor, and Line Frequency information.
Note: UPS’s with dual output voltages offer the option of selecting and
viewing the VOLTAGE and CURRENT of each output individually.
Voltage
Output Voltage #1 displays the true RMS voltage for the 120 VAC side
(i.e., all 120 volt receptacles) and the voltage between L1 and N on the output
terminal block.
Output Voltage #2 displays the true RMS voltage for the 208 VAC or 240
VAC (i.e., all 208 VC or 240 VAC output receptacles) and the voltage between L1
and L2 on the output terminal block.
NOTE: The voltage between N and L2 can be calculated by subtracting
Output Voltage #1 from Output Voltage #2.
The “INPUT PARAMETERS” provide UPS Input Voltage, Current, Volt
Amps, Power in Watts, Power Factor, and Line Frequency information.
Voltage
The voltage measured at the input of the UPS (i.e., 120 VAC).
Current
The flow of current measured at the input of the UPS (i.e., 3.1 Amps).
Volt Amps
The apparent input power of the UPS calculated by multiplying input voltage
by the input current (i.e., 663 VA).
Power in Watts
The true input power of the UPS calculated in Watts (i.e., 600 Watts).
Power Factor
The ratio of true power (power actually consumed) to apparent power (simple
product of voltage and current) at the input of the UPS (i.e., 0.89).
Line Frequency
The frequency of the AC Line measured at the input of the UPS (i.e., 60 HZ).
