1. Important Safety Instructions

SAVE THESE INSTRUCTIONS

This manual contains instructions and warnings that should be
followed during the installation, operation, and storage of this product.
Failure to heed these instructions and warnings will void the product
warranty.

The PDU provides convenient multiple outlets, but it DOES NOT provide surge or line noise •
protection for connected equipment.

The PDU is designed for indoor use only in a controlled environment away from excess moisture, •
temperature extremes, conductive contaminants, dust or direct sunlight.

Do not connect the PDU to an ungrounded outlet or to extension cords or adapters that eliminate the •
connection to ground.

The power requirement for each piece of equipment connected to the PDU must not exceed the •
individual outlet’s load rating.

The total power requirement for equipment connected to the PDU must not exceed the maximum load •
rating for the PDU.

Do not drill into or attempt to open any part of the PDU housing. There are no user-serviceable parts •
inside.

Do not attempt to modify the PDU, including the input plugs and power cables.•

Do not attempt to use the PDU if any part of it becomes damaged.•

Do not attempt to mount the PDU to an insecure or unstable surface.•

Never attempt to install electrical equipment during a thunderstorm.•

Use of this equipment in life support applications where failure of this equipment can reasonably be •
expected to cause the failure of the life support equipment or to significantly affect its safety or
effectiveness is not recommended. Do not use this equipment in the presence of a flammable
anesthetic mixture with air, oxygen or nitrous oxide.

2. Installation

2.1 Mounting the PDU

The PDU supports four primary mounting
configurations: 1U Rack, 0U Rack, Wall and
Under-Counter.

Note: Regardless of configuration, the user must determine the
fitness of hardware and procedures before mounting. The PDU
and included hardware are designed for common rack and rack
enclosure types and may not be appropriate for all applications.
Exact mounting configurations may vary.

1-1 1U Rack Mounting: Attach the PDU to the

rack by inserting four user-supplied screws A
through the PDU mounting brackets B and into
the mounting holes of the rack rail as shown.

1-2 0U Rack Mounting: Remove the screws C

attaching the mounting brackets to the PDU,
change the orientation of the brackets as shown
and reattach the brackets. Use only the screws
supplied by the manufacturer or their exact
equivalent (#6-32, 1/4" flat head). Attach the
PDU vertically by inserting two or more user­supplied screws A through the PDU mounting
brackets B and into mounting points in the rack
or rack enclosure.

1-3 Wall or 1-4 Under-Counter Mounting:

Remove the screws C attaching the mounting
brackets to the PDU, change the orientation of the
brackets as shown and reattach the brackets. Use
only the screws supplied by the manufacturer or
their exact equivalent (#6-32, 1/4" flat head).
Attach the PDU to a stable mounting surface by
inserting two or more user-supplied screws A
through the PDU mounting brackets B and into
secure points on the mounting surface.

2.2 Connecting the PDU

The PDU includes two AC power inputs: Primary
and Secondary. The Primary input cord is
permanently attached to the rear of the PDU.

The Secondary input cord is detachable and
connects to the IEC power inlet 2 at the rear of
the PDU (PDUMH15AT,PDUMH15ATNET ­IEC-320-C14 inlet; PDUMH20AT,
PDUMH20ATNET - IEC-320-C20 inlet).

2-1 To connect the Secondary input cord:

Form a loop in the Secondary cord 1.
secure the juncture of that loop to the Primary
cord B with a zip tie. Be sure the zip tie is
secured around the Secondary and Primary
cords, as well as through the loop created in
the Secondary cord C. (See diagram). Note:

Give the cord as much slack as possible
between the loop and the cord’s outlet.

Once you’ve secured the two cords together 2.
and ensured that the Secondary cord has a
comfortable amount of slack, insert the
Secondary cord outlet into the IEC power inlet.

2.2 Connecting the PDU

2-2 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.

2-3 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.

2-4 Connect PDU Input Plugs: (See the

Configuration and Operation section for more
information.) Connect the Primary input plug A
to a preferred source of grounded 120V AC
power, such as a SmartOnline™ UPS 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 B to an alternative 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.

3 Connect Equipment to PDU: Do not exceed

the load rating of the PDU. The total electrical
current used by the PDU will be displayed on the
digital meter in amperes. Each outlet includes a
green LED that illuminates when the outlet is
receiving AC power.
