2.2B Connect Input Plug Adapters
(Optional - Models PDUMH20AT,
PDUMH20ATNET Only): The PDU includes two
adapters that convert one or both of the
L5-20P input plugs to 5-20P input plugs.
Connecting the adapters is optional. The PDU
will function normally without connecting the
adapters.
2.2C Connect Secondary Input Cord to
PDU: Although the PDU will operate without
connecting the Secondary input cord, the
Secondary input is required for the PDU's
Automatic Transfer Switch function.
2.2D Connect PDU Input Plugs: (See the
Configuration and Operation section for more
information.) Connect the Primary input plug

power, such as a SmartOnline

source of grounded 120V AC power, such as a
redundant SmartOnline UPS System. The UPS
system must not share a circuit with a heavy
electrical load (such as an air conditioner or
refrigerator). 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.
