Note: The battery must be at least partially charged for this operation to succeed.

•With the external battery cabinet connected, switch on the circuit breaker of the external battery cabinet.

• Confirm that the main input circuit breaker switch Q1 , bypass input circuit breaker switch Q2 , manual bypass circuit breaker

switch Q3 and output circuit breaker switch Q4 are all off.

•Press the ON button for 3 seconds (until you hear a beep), then

	release the button. The inverter will activate and use stored DC

	battery power to supply AC power to the output circuit breaker.

	The “BATTERY” LED	will illuminate.
	Warning: The output voltage and frequency must be set to the

	desired values PRIOR to applying UPS inverter output to the

Warning: Placing the UPS system in manual bypass will disable the inverter and power all loads from the manual bypass source path, but

11 the UPS system will still be energized. Before performing maintenance or repair on the UPS system, shut down and de-energize the UPS system completely by following the steps in Section 8-5. Although connected equipment loads will be powered through the bypass power path, they will not receive battery backup in the event of a utility power failure or out limits event.

To transfer the connected equipment load to Manual Bypass from NORMAL mode:

•With the UPS in NORMAL mode (green LED ON, LCD displays “Load Protected – On Line Mode”), stop the inverter by

pressing and holding the red OFF (“O”) button until the UPS beeps, then release the button and answer “YES” to the question “Transfer to Bypass Mode?”. The UPS should transfer to Bypass.

•Confirm the UPS is in BYPASS mode (amber Bypass LED is ON; LCD displays “Load Unprotected – On Auto Bypass”). Do not proceed if it is not in BYPASS mode.
