8-10 Switching to Manual Bypass Mode from Normal Mode Procedure (Parallel UPS—MUS)

Warning: When the UPS system is in manual bypass, the inverter shuts down. Connected equipment loads are powered by the bypass	2
power path and will not receive battery backup during a utility power failure or out of limits event.

•For the first UPS system you wish to transfer to manual bypass

	mode, press the OFF button	for 3 seconds (until you hear
	a beep), then release the button. If the other UPS systems can
	support the connected equipment loads, the UPS system that was								3
	turned off will shut down its inverter and its LCD screen will read								3

	“LOAD NOT POWERED”. All other UPS systems’ LCD screens
	will read “ONLINE MODE”. If the total connected equipment load
	is too large to be handled by the remaining UPS systems, all UPS							A
	systems will shut down their inverters and switch to bypass mode,			1				A	4

	and their LCD screens will read “ON AUTO BYPASS”. Repeat
	step 1 for each UPS system you wish to transfer to manual bypass
	mode.
