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 Active Input
LED will be lit. When the Primary input
UPS has been restarted and resumes
supplying AC power, the PDU will switch
back to the Primary input, and the
Primary Active Input LED will be lit.
Primary Input Active
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.
Secondary Input Active
