Three-Phase Rack PDU — Installation and Operation Manual i
Product Description and Inventory
Description
Inventory
This manual provides information on installing and operating three Rack
PDUs (AP7601, AP7602, and AP7608), which mount vertically in the
rear channel of an APC NetShelter VX Enclosure.
Each of these PDUs has a sensor that measures the current being used by
the PDU and its attached devices. The display interface shows the
aggregate current of an individual phase. An alarm occurs if the
aggregate current is above the high threshold value or below the low
threshold values that you configure. These PDUs have the following
plugs and outlets:
PDU Plug Number and Type of Outlets
AP7601 L21-20 42 NEMA 5-20R
AP7602 L21-20 21 NEMA 5-20R and 6 L6-20R
AP7608 L21-20 42 IEC-320-C13

Hardware end cap 870-70803 1
Hardware access cover 870-70804 1
Note: Bracket kits (AR8116BLK) are available for Rack PDUs.

How to Install the Rack PDUs
Installation guidelines
Mounting options
• If the PDU is installed in an enclosed communications rack, the
recommended maximum ambient temperature should be no greater
than 45°C.
• Install the PDU so that the amount of air flow required for safe
operation of the equipment is not compromised.
• Install the PDU so that there is not an uneven mechanical load.
• Follow the nameplate ratings when connecting equipment to the
supply circuit. Take into consideration the effect that overloading
the circuits might have on over-circuit protection and supply
wiring.
• Maintain reliable earthing of the PDU. Give particular
consideration to supply connects that do not directly connect to the
branch circuit.
• Install the PDU so that the power plug may be disconnected for
service.
You can install Rack PDUs in one of two ways: using toolless mounting
pegs or the mounting brackets. The Rack PDU mounts in the rear of the
enclosure, in the channel directly behind the rear vertical mounting rails.
Before you begin to install the Rack PDUs, choose a location in the
enclosure and decide on the mounting method.
Three-Phase Rack PDU — Installation and Operation Manual 3
How to Install the Rack PDUs
Toolless mounting
1. Slide the mounting pegs into the holes provided in the channel in
the rear panel of the enclosure. Make sure the bottom pegs slide
into the bottom holes in the enclosure.
2. Snap the Rack PDU into place by pushing it downward until it
locks into position.
4 Three-Phase Rack PDU — Installation and Operation Manual
How to Install the Rack PDUs
Bracket-mounting
You can order a rack-mount bracket kit from APC—AR8116BLK. You
attach the brackets to the Rack PDU in one of the two directions shown
in the figures in step 1. Consider the orientation of the Rack PDU in the
enclosure before attaching the brackets. A recessed orientation allows
the Rack PDU to be mounted flush with the enclosure; a raised
orientation allows you to route cables through the channel (see the
figures in step 2).
1. Attach two brackets to the rear of the Rack PDU, using six panhead screws (provided in the bracket kit) for each bracket.
– Recessed Orientation
– Raised Orientation

How to Install the Rack PDUs
2. Insert one mounting screw (provided with the bracket kit) in the
top and bottom positions in the channel where the brackets align
with the holes. Tighten the screw to secure the Rack PDU to the
enclosure.

Note
If you have InfraStruXure Manager as part of your system,
you can use InfraStruXure Manager’s Web interface to
configure the same values that are configured through a
serial port.
How to configure the PDU through a serial port
1. Connect an available serial port on your computer to the serial port
on the Rack PDU, using the supplied configuration cable
(990-0144). The PDU’s serial port is shown below.
2. Run a terminal emulation program such as Windows
®
HyperTerminal.
3. Configure the following settings for the serial port:
– 19,200 bps
–no parity
–8 data bits
–1 stop bit
– no flow control
Some terminal emulation programs require that a
device be disconnected and then reconnected for the
Note
new serial port settings to take effect.
4. Press any key on the computer to display the PDU login screen,
which contains the Username and Password prompts.
