5.1Switching On the UPS System / from Maintenance Bypass

Initial UPS Operating Mode:

The UPS is switched off, the load may or may not be supplied by maintenance bypass, IBY and all other power switches are open.

Operating Steps:

A:	•	Switch on the external mains supply for the UPS; both the
		rectifier input and the bypass input when separate supplies are
		provided.
	•	Open the UPS front door or the part necessary to allow access
		to the switches IRP, IRE, IUG and IBY.
IBY:		If the b ypass switch IBY, is not already on, close it now (for
		parallel systems with internal maintenance bypasses see Note
		1 page11) The load is now supplied by the maintenance by-
		pass.
IRP:	•	Close the IRP switch.
		The rectifier starts and the UPS performs a self-test.
		The UPS operating panel will beep 3 times and test all the
		LEDs. The audible alarm may continue beeping and can be
		muted by pressing "RESET" once.
IUG:	•	Close the IUG switch.
IRE:	•	Close the IRE switch.
IB:	•	Close the battery switch IB.

Repeat A above, for all units within the system (Hot-standby and

Parallel systems).

B:	•	Check that the LEDs for the bypass and the output are illumi-
		nated.
IBY:	•	Open the IBY switch inside all units (or within the External
		Maintenance Bypass cabinet if installed).
RESET:	•	Press the pushbutton "RESET" on the operating panel of any
		unit.
START:	•	Press the pushbutton "START" on the operating panel of all
		units within the system. The inverter(s) will start and will switch
		over to take the load when ready (SSI closes).

Note: The pushbuttons "START" and "RESET" must be depressed for about 1 sec.
