General Information
Introduction
The American Power Conversion NetworkAIR® Rack Air Removal Unit removes heat generated by
the exhaust of equipment contained in a NetShelter VX or NetShelter EP EIA 19-inch enclosure. The
three fans provide increased air flow needed to cool densely-packed equipment and allow air to
bypass obstacles in the rear of the enclosure such as power and data cables. An optional duct kit
removes the heat entirely from the data center.
Features
Features of the Rack Air Removal Unit:
• Variable fan settings — based on power load and user-definable exhaust temperature
• Dual input connectors — for redundant power
• Three individually fused fans — allows unit to be used for redundancy or higher capacity
• Alarm LEDs — system status, fan status, and thermal control status
• Duct kit — for removal of heat from the air-conditioned space (optional)
• Integrated smoke detector (optional)
• APC Environmental Management System — for remote control and monitoring of the Rack Air
Removal Unit (optional)

Safety Information
For computer-room use only.
Warning
Install the Rack Air Removal Unit only on racks that are loaded with equipment,
counter-weighted, or stabilized to avoid tipping of the rack.
Inspect the Rack Air Removal Unit for damage before installation.
Disconnect power to the Rack Air Removal Unit before installing it into the rack.
Failure to do so may result in personal injury or damage to equipment.
Do not apply power to the unit until the installation is complete. The Rack Air
Removal Unit contains moving parts, which are potentially hazardous when
operated outside of the rack.
Do not attempt to move a heavily-loaded enclosure by yourself. Doing so
introduces risk of injury due to muscle strain or to tipping of the enclosure.
Fully-loaded enclosures require at least two people to move safely.
Do not attempt to install the Rack Air Removal Unit by yourself. Doing so
introduces risk of injury due to muscle strain or to tipping of the enclosure. The
Rack Air Removal Unit requires at least three people to install safely.
Check that the power cord plugs and sockets are in good condition before
installation.
Connect the Rack Air Removal Unit to 230V IEC C-13 outlet. The outlet must
be connected to appropriate branch circuit/mains protection (fuse or circuit
breaker). Connection to any other type of outlet may result in a shock hazard.
This equipment contains potentially hazardous voltages. Do not attempt to
disassemble the unit.
Always install and operate the Rack Air Removal Unit as shown in this manual.
Installing the Rack Air Removal Unit requires three people. Do not attempt to lift
the Rack Air Removal Unit without assistance.

Installation
Install the fan frame
To avoid personal injury or damage to the enclosure, one person should support
the fan frame while another places the fan frame onto the enclosure.
Warning
Install the Rack Air Removal Unit only on racks that are loaded with equipment
or are counter-weighted to avoid tipping of the rack.
Warning
1. With the exhaust vent at the top of the fan frame,
align the four corners of the fan frame to the four
corners of the enclosure. The spring-loaded pins at
the bottom of the fan frame will line up with the
hinge-pin brackets on the enclosure.
2. Insert the spring-loaded pins at the bottom of the
fan frame into the holes.
3. Pull the spring-loaded pins at the top of the fan
frame and release the pins into the holes.

Warning
Warning
To avoid personal injury or damage to the Rack Air Removal Unit or the
enclosure, two people should support the fan assembly while another places the
fan assembly onto the enclosure.
1. Align the lower pin with the hole in the hinge
pin bracket on the fan frame and insert the pin
into the hole.
2. Align the upper hinge hole with the hole in
the upper hinge pin bracket and insert the
hinge screw into the holes.
3. Tighten the hinge screw with the included
5/32" hex wrench.

Optional Items
American Power Conversion offers additional products (not included) for the Rack Air Removal
Unit:
• Smoke Detector Kit (ACF121) — mounting plate and smoke detector for use inside the Rack
Air Removal Unit.
• Air Duct Kit (ACF120) — for removal of heat from the air conditioned area. If using the
optional duct kit with the temperature setpoint mode, you will need to monitor the room
temperature for the first 24 hours, and adjust your setpoint to maintain the proper temperature
differential (see “How to set the fans based on temperature” on page 14).
• APC Environmental Management System (AP9320) — monitoring unit and A-Link
connections for monitoring and controlling the Rack Air Removal Unit from a remote location.

Operation
Connect the power supply
1. Set the fan speed selector to OFF.
2. Using one of the supplied power cords, connect the female end to the "A" input socket on the
inside of the unit. Plug the male end into a power-protected socket. Ensure that there is adequate
power for the fans to run at 100% (230V 4 A). The UPS in the rack must be sized properly to
power this unit.
Use the Rack Air Removal Unit only with a 3000 watt UPS or higher. The UPS
should not be loaded above 80% when using the Rack Air Removal Unit.
Warning
3. To provide redundant power to the unit, use the "B" input socket to connect to a second source
of protected power.
4. Attach the cord retainer to lock the cords in place.
Cords may be bundled and tie-wrapped to provide clearance for other components.
Note

Operation
To check operation of the unit:
5. Apply power to the fans by turning the fan speed selector from the OFF position to one of the
four exhaust temperature settings.
6. Make sure the fans are moving.
7. Turn off the power to the unit.
If no air is flowing from the Rack Air Removal Unit, check the power connection.

How to set the fans based on wattage
Determine the wattage of your equipment and set the fan speed selector to the corresponding kW
setting.

Setting the kW setpoint too low could damage the equipment in the enclosure. If
the amount of kW in your enclosure falls between two of the numbers on the
setpoint dial, choose the higher number or set based on exhaust temperature.
When the temperature override is enabled and the temperature in the rack rises above
40.5° C (105° F), the Rack Air Removal Unit will automatically increase the fan speed
to bring the temperature below 40.5° C (105° F).
When in kW mode and using a UPS that is 3000VA or lower, disable the
temperature override to prevent the power draw from exceeding the limitations
of the UPS.
The UPS should not be loaded above 80% when using the Rack Air Removal
Unit.
Temperature override
The kW settings on the fan speed selector run the fans at a constant speed, while the exhaust
temperature settings adjust the fan speed depending on the exhaust temperature of the equipment in
the rack. The Rack Air Removal Unit is equipped with a temperature override that protects the
equipment in the rack while the unit is in kW mode. If the unit is in kW mode, and the exhaust
temperature rises above 40.5° C (105° F) (the override setpoint), the unit increases the fan speed to
remove excess heat from the rack.

Operation
How to set the fans based on temperature
A temperature probe is located in the intake vents of the Rack Air Removal Unit that measures the
equipment exhaust air temperature. The unit will increase or decrease the speed of the fans to keep
the equipment exhaust at the desired temperature.
The appropriate fan speed is based on the equipment’s inlet air temperature and its temperature
differential. The temperature differential is the rise in temperature between the inlet air and the
exhaust air after it passes through the equipment. Refer to your equipment manual to determine the
temperature differential.

How to Communicate Using the A-Link
The Rack Air Removal Unit can be used with an APC Environmental Management System that can
monitor and control the unit. Connect the APC Environmental Management System any Rack Air
Removal Units by using the in and out A-Link connections.
How to connect to the A-Link
The Rack Air Removal Unit has two connections (IN and OUT) for linking several devices together
using the A-Link. The Rack Air Removal Unit must be given an address to communicate with the
APC Environmental Management System. The address DIP switch is recessed inside the space
marked A-Link Address. Use a small tool such as a pocket screwdriver to set the DIP switch to the
correct position.
Remove power from the Rack Air Removal Unit before setting DIP switches or
connecting other devices.
Warning
To remotely monitor the Rack Air Removal Unit:
1. Set the second, third, and fourth DIP switches to
give the Rack Air Removal Unit a unique A-Link
address between one and eight, according to the
chart.
