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.
Primary Input Active Secondary Input Active
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.
