Temperature/Humidity Module 3

Installation—TH Module

You can install the TH Module in the front or the
rear of the rack or enclosure, using either the rack­mount option, which uses 1 U of rack space, or the
toolless peg-mount option, which uses no U-space
(the toolless peg-mount option is available only
with APC racks and enclosures).

Toolless peg-mount installation

This option may not be available with
all racks.

Note

1. Slide both mounting pegs into the holes
located in the cable channel in the rear panel of
the rack.

2. Snap the TH Module into place by pushing it
downward until it locks into position.

Rack-mount installation

1. Remove the toolless mounting pegs located at
the front of the unit.

2. Attach the brackets (provided) to each end of
the TH Module, using two screws for each
bracket.

3. Choose a location in the rack for the TH
Module.

Installation—Accessories

Sensors

Selecting a location for the sensor:

Install the sensor in a location that represents the
air to be monitored. Avoid placing the sensor
anywhere that may affect the sensor reading, such
as near windows, room entrances, air ducts, other
heat sources, or in direct sunlight.

To install a sensor on the vertical rail of an

2. Thread a wire tie through the door holes,
skipping one hole in the middle.

If you have a temperature/humidity sensor,

place the sensor in the middle of the wire
tie, and pull the wire tie around a ridge on
the sensor casing.

If you have a temperature sensor, pull the

wire tie around the sensor cord, about 1/2-in
(1 1/4-cm) from the sensor.

3. Tighten and trim the wire tie.

4. To route the sensor cord, choose a location on
the inside of the door frame that is even with
the sensor.

5. Peel the backing off the adhesive side of a
cable mount, and press the cable mount firmly
to the inside of the door frame. Thread a wire
tie through the cable mount, and secure the
sensor cord with the wire tie. Tighten and trim
the wire tie

6. To secure the sensor cord, choose a location
near the middle of the door frame, and repeat
step 5.

rack first. When routing the
sensor cord closest to the middle
of the rack, secure all sensor
cords in the wire tie.

7. With the door fully open, thread the sensor
cords through the opening in the front post of
the rack.

aem007 6a

8. Route the cords between the vertical support
rail and the side panel. Each 13-ft (4-m) sensor
cord may be extended to a maximum of 50 ft
(15 m), using RJ-45 couplings and standard
CAT5 cables.

To install sensors in another location:

1. Use one of the following methods, depending
on the type of surface on which you are
mounting the sensor:

To mount the sensor on a wall or other

smooth surface, peel the backing off the
adhesive of the sensor mount, and place the
sensor mount onto the wall.

To mount the sensor on a rough wall or

porous surface, first install the wall anchor.
Then attach the adhesive sensor mount to
the wall anchor using the provided flat-head
screw.

2. Thread a wire tie through the sensor mount,
and secure the sensor with the tie. Tighten the
wire tie and trim any excess.

Neatly route the sensor cord and connect the

sensor to the APC device.

3. Thread a wire tie through the sensor mount,
and secure the sensor with the tie. Tighten the
wire tie and trim any excess.

4. Neatly route the sensor cord and connect the
sensor to the Main Module or TH Module.

8 Temperature/Humidity Module

Installation—Accessories

Alarm beacon

1. Install the alarm beacon in a visible position
either on the roof of the rack or inside the rack.

2. If you install the beacon on the roof, route its
cable through the provided holes, as shown in
the following illustration.

3. Plug the cable into the Alarm Beacon port.

4. The cable may be extended to a maximum of
330 feet (100 m), using RJ-45 couplings and
standard CAT5 cables.

User inputs (optional)

There are four user input connection points
provided on the TH Module. These inputs use
screw terminal connections. Each may optionally
be configured as:

• 5 V dry contact input (Normally Open [N.O.]
or Normally Closed [N.C.])

• 0–5 VDC digital input

The following examples show connections for
N.O. and N.C. dry contacts.

Setting unique identifier numbers

Each TH Module should have its own unique
identifier number, which is used in the Main
Module’s interface to identify and configure this
TH Module.

Use the arrow button to the right of the Identifier #
LED display to set a unique number from 01 to 32
for each TH Module in your system. Do not
connect more than 32 TH Modules to the Main
Module.

When you apply power to the module during the
initial installation, all modules will automatically
receive a unique identification address. If you
manually select duplicate identifiers, the Identifier
# LEDs on the duplicated units will flash.

Additional TH Modules

Add TH Modules to the Main Module to monitor
additional racks. The Main Module can support a
maximum of 32 TH Modules (with additional
power supplies).

Adding power supplies:

The first time a TH Module receives
power, it requests a unique
identification address from the Main

Warning

Module. It uses this address to
communicate with the Main Module.
If the TH Module is not part of the
system when it receives power for
the first time, it cannot ensure that
its identifier is unique, and
communication problems may arise.

To avoid communication problems, connect the
TH Module to the Main Module or a TH Module
that is part of the system before connecting a
stabilized power supply to the 24 VDC Input.
