Quick Test
After installing the PDU and connecting
equipment, you may test the Automatic
Transfer Switch function by temporarily
shutting down the UPS system connected to the
Primary AC input. When the Primary input UPS
is no longer supplying AC power, the PDU will
switch from the Primary input to the Secondary
input, and the Secondary input LED will
illuminate. When the Primary input UPS has
been restarted and resumes supplying AC power,
the PDU will switch back to the Primary input.
Note: The primary and secondary inputs must be connected to
separate sources of utility power. The automatic transfer switch
function will be compromised if the primary and secondary
inputs are connected to the same utility power source. Do not
perform a test with equipment that must remain in productive
operation. Any test procedure must prepare for the contingency
that the equipment may lose power. Do not test the PDU by
detaching power cords which are connected to live power
sources, as this eliminates the connection to ground and places
your equipment at risk.
