Rack Air Removal Unit

General Information

Overview

Product description

The American Power Conversion (APC®) Rack Air Removal Unit SX (ARU) removes heat generated
by the equipment contained in a NetShelter
(ACF115) and a mounting frame (ACF136 or ACF137). Four fans provide airflow to remove hot exhaust
from densely packed equipment and allow air to overcome resistance of power and data cables in the rear
of the enclosure. A ducting kit, sold separately, connects to a ceiling plenum and removes the heat
entirely from the room.

ACF400. Features of the Rack Air Removal Unit SX include the following:

• Fault tolerant fan system

• Dual A-B power inputs

• Integrated network management card

• Integrated LCD display

Additional items sold separately:

• Duct kit (ACF126, ACF127) - Connects fan box to ceiling plenum (Recommended)

• Alarm beacon (AP9324) - flashes when alarm condition exists (Optional)

• Remote temperature sensor (AP9335T) - connect up to three sensors (Optional)

®

SX or VX enclosure. The ARU consists of a fan box

See: Application Note AN-109Rack Air Removal Unit SX Application Guidelines for more
information.

Safety Information

HAZARD OF ELECTRIC SHOCK

• Connect the Rack Air Removal Unit SX to a three-wire, grounded outlet. The outlet
must be connected to appropriate branch circuit or 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.

Failure to follow these instructions can result in death or serious injury.

DAMAGE HAZARD

• Install the Rack Air Removal Unit SX only on an enclosure that is loaded with
equipment, counter-weighted, or stabilized to avoid tipping of the enclosure.

• Inspect the Rack Air Removal Unit SX for damage before installation.

• Do not apply power to the unit until the installation is complete. The Rack Air
Removal Unit SX contains moving parts, which are potentially hazardous when
operated outside of the enclosure.

• Do not allow loose hair or clothing near the fans because the fans create suction.

• Check that the power cord plugs and sockets are in good condition before
installation.

• Always install and operate the Rack Air Removal Unit SX only as shown in this
manual.

• There are no customer-serviceable items on the Rack Air Removal Unit SX. Do not
attempt to open or repair the Rack Air Removal Unit SX.

DANGER

WARNING

Failure to follow these instructions can result in death, serious injury, or
equipment damage.

CAUTION

INJURY HAZARD

Do not attempt to install the Rack Air Removal Unit SX by yourself. Doing so
introduces the risk of injury. The Rack Air Removal Unit SX requires at least two
people to install it safely..

Failure to follow these instructions can result in injury or equipment damage.

WARNING

TIPPING OR DAMAGE HAZARD

• To avoid personal injury or damage to the enclosure, one person should support
the door while another person removes it from the frame.

• If the enclosure is not joined to other enclosures, ensure it contains sufficient
weight or has adequate support to prevent it tipping during ARU installation.

Failure to follow these instructions can result in serious injury, or
equipment damage.

1. If necessary, move the enclosure to allow at least 762 mm
(30 in) of clearance at the rear of the enclosure to install
the ARU.

2. Disconnect the grounding wires from each door.

3. Remove the grounding wires from the rack to enable the
ARU to fit properly.

4. Remove the rear doors from the enclosure.

Removing doors from an SX enclosure. Open the door 90

degrees and lift it up and off its hinges.

Removing doors from a VX enclosure.

1. Open the rear doors and pull down on the
spring-loaded hinge pin. Lift the doors
from their frame.

The anti-tip strap prevents the enclosure from tipping to the
side before the enclosure is stabilized.

Using the M6 shoulder hex screw and lock washer (provided),
attach the anti-tip strap.

CAUTION

TIPPING HAZARD

Do not remove the anti-tip strap after it has been installed. Lowering the leveling feet
of the enclosure will help stabilize it, but will not prevent it from tipping over.

Failure to follow these instructions can result in equipment damage.

Connect the ground wire

To ground the unit, attach the ground wire connected to the fan
assembly to the ground wire connected to the mounting frame.

kW Support

This kW value can be used to help you to pick the appropriate flow rate based on power draw of the
equipment in the rack. The kW value is a calculated value based on the Tot al F lo w and the Operating
