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 may affect 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 1U Rack configurations.
	Note: The user must determine the fitness of hardware and	B
	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.
	2.1.1 1U Rack Mounting: Attach the PDU to	A
		PDUMH15AT, PDUMH15ATNET,
	the rack by inserting four user-supplied screws A
		PDUMH20AT, PDUMH20ATNET
	through the PDU mounting brackets B and into
	the mounting holes of the rack rail as shown.	B

2.Installation (continued)

2.2Connecting the PDU

The PDU includes two AC power inputs: Primary		Primary Input (120V Models)
and Secondary. The Primary input cord is
permanently attached to the rear of the PDU
(120V models).
IEC-320-C14 inlet is used for the primary input
of the 230V model.
The Secondary input cord is detachable and		PDUMH15AT		PDUMH20AT
connects to the IEC power inlet 2.2.1 at the rear	2.2.1
		PDUMH15ATNET		PDUMH20ATNET
of the PDU (PDUMH15AT, PDUMH15ATNET -		Primary Input (230V Model)
IEC-320-C14 inlet; PDUMH20AT,
PDUMH20ATNET, PDUMH20HVAT,
PDUMH20HVATNET - IEC-320-C20 inlet).		Unswitched Outlets	SecondaryInput	PrimaryInput
1. Form a loop in the Secondary cord A and
2.2.2 To connect the Secondary input cord:
secure the juncture of that loop to the Primary
cord B with a zip tie. Be sure the zip tie is	2.2.1 230V PDUMH20HVAT & PDUMH20HVATNET
secured around the Secondary and Primary
cords, as well as through the loop created in
the Secondary cord C . (See diagram). Note:			A
Give the cord as much slack as possible
between the loop and the cord’s outlet.		B
2. On Models PDUMH20HVAT and
PDUMH20HVATNET, both cords should be		C
tied to the Cable Retention Tray. (See
diagram).
3. Once you’ve secured the two cords together
and ensured that the Secondary cord has a
comfortable amount of slack, insert the
Secondary cord outlet into the IEC power inlet.
2.2.3 Connect Input Plug Adapters (Optional	2.2.2
- 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	2.2.3			PDUMH20AT,
connecting the adapters.				PDUMH20ATNET
2.2.4 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.
2.2.5 C19-C20 Cables (optional: Models	2.2.4	PDUMH15AT,		PDUMH20AT,
		PDUMH15ATNET		PDUMH20ATNET
PDUMH20HVAT and PDUMH20HVATNET
only): The PDU includes two C19 to C20
interconnection cables for the two primary and		Unswitched Outlets	SecondaryInput	Primary
secondary inlets, which may be used to connect
to upstream UPS sources. Alternately, the user	2.2.5
can supply IEC cables fitted with country-specific		PDUMH20HVAT & PDUMH20HVATNET
plugs.

2.Installation (continued)

2.2Connecting the PDU (continued)

2.2.6 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/230V AC power,
such as a SmartOnline™ UPS System. The UPS		A
system must not share a circuit with a heavy
electrical load (such as an air conditioner or
refrigerator). Under normal operating conditions,			B	PDUMH15AT,
the PDU will distribute AC power from the Primary				PDUMH15ATNET
input source. Connect the Secondary input plug B
to an alternative source of grounded 120V/230V 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			A	PDUMH20AT,
Primary input. The PDU will distribute AC power
				PDUMH20ATNET
from the Secondary input only if the Primary input
becomes unavailable.
Note: Immediately after the PDU is connected to live AC			B
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.
2.2.7 Selecting Input Voltage Range (optional:
Models PDUMH20HVAT &
PDUMNH20HVATNET only): This model has two
selectable nominal input voltage ranges: 200V-208V
(“LO”) and 220V-240V (“HI”). Press the switch			A
next to the display to toggle the nominal voltage				PDUMH20HVAT &
setting to the desired “HI” or “LO” range. This
setting adjusts the voltage ranges for the primary				PDUMH20HVATNET
and secondary inputs. The display will indicate “HI”				Unswitched Outlets
or “LO” for five seconds.
2.2.8 Connect Equipment to PDU: Do not				B
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		2.2.6
a green LED that illuminates when the outlet is
receiving AC power.
