Operating Instructions

During normal operation,
mains power provides energy
to the UPS. The filters, power
factor correction circuit and
the inverter process this
power to provide computer
grade power to connected
loads. The UPS maintains
the batteries in a fully
charged state.
Bypass mode occurs when
the OFF button is pressed
once while the UPS is in Nor-
mal Mode. During bypass
operation, mains power pro-
vides energy to the UPS. The
mains power bypasses the
inverter and provides power
for the connected load.
