2.2.5 C13-C14 (Models:
PDUMH15HVAT and
PDUMH15HVATNET) or C19-C20
Cables (Models PDUMH20HVAT
and PDUMH20HVATNET only):
The PDU includes one C13 to C14
(PDUMH15HVAT/NET) or two C19 to C20
(PDUMH20HVAT/NET) interconnection cables
for the two primary and secondary inlets,
which may be used to connect to upstream
UPS sources. Alternately, the user can supply
IEC cables fitted with country-specific plugs.
2.2.6 Connect PDU Input Plugs:
(See the Configuration and Operation section for more information.) Connect the Primary input
plug to a preferred source of grounded 120V/230V AC power, such as a SmartOnline
A
System. The UPS system must not share a circuit with a heavy electrical load (such as an air
conditioner or refrigerator). Under normal operating conditions, the PDU will distribute AC power
from the Primary input source. Connect the Secondary input plug
grounded 120V/230V AC power, such as a redundant SmartOnline UPS System. Do not plug the
Secondary input into the same power source as the Primary input. The PDU will distribute AC power
from the Secondary input only if the Primary input becomes unavailable.
Note: Immediately after the PDU is connected to live AC power, you may notice a series of soft clicking sounds
emitted by electrical relays within the PDU. The relays may also click occasionally during the operation of the
PDU. This is normal.
