tions are the TEMP ALARM, DOOR ALARM, and power
connections (BLK ‐V and RED +V). To make the power con
nections, uncoil the wires attached at the left interior wall of the
cabinet to expose the stub ends (the other end is factory‐wired
to the controller card). To make the TEMP/DOOR ALARM
connections to the Euro‐connector, pull‐off the Euro‐connec
tor, strip approximately 3/8” off the end of each field‐provided
wire, insert wire(s) into hole(s), tighten screws, and push‐on
the Euro‐connector.

1.
Fan Terminal Block
. The internal temperature‐controlled
fans require a ‐48VDC, 1.75A or +24V, 3.5A power source
to be wired to the Euro‐connector located at the bottom left
corner of the Controller Card.
2.
Temperature Alarm Terminal Block
. A Normally Open Tem
perature Alarm thermostat contact closes when the internal
cabinet temperature exceeds 65° C and will remain on until
the temperature drops below 55° C. For temperature alarm
connections, connect alarm wiring from the field‐provided
alarm equipment to the 2‐position Euro‐connector at the
top left of the controller card.
3.
Door Alarm Terminal Block
. A Normally‐Open Door Alarm
contact closes when the door is opened. For door alarm con
nections, connect wiring from the field‐provided alarm
equipment to the 2‐position Euro‐connector at the top left
of the controller card.
4.
Power connections.
A Euro connector is prewired to a 48” red
and black cable stub. For +24V power applications, connect
the red wire to the +24V source and connect the black wire
to ground. For ‐48V power applications, connect the black
wire to the ‐48V source and the red wire to ground.
2.2.7
Grounding and Bonding Center
Boxer's grounding and bonding center is located on the bottom
interior surface of the cabinet, close to the front door. A
ground plate is provided that contains eight sets of ground
posts and one copper ground lug, for cable and chassis/earth
ground. Bond equipment/cables to the ground posts per com
pany practice, and connect a #6 AWG chassis or earth ground
wire to the ground lug. Ground lug hardware should be
tightened to 20 inch‐pounds. An Electro‐Static Discharge
(ESD) wrist‐strap jack is also located on the ground plate.

INSTALLATION
Use and follow local codes and company practices to install the
Westell Boxer
r
cabinet. If none exist, use the instructions con
tained herein. Installation consists of:
S
inspecting the unit for damages that may have incurred dur
ing shipping,
S
following proper safety precautions,
S
reviewing pre‐mounting considerations, such as selecting the
mounting type and location, and preparing the mounting site,
S
gathering all tools, materials, and equipment,
S
removing any knock‐outs where access holes are required,
S
mounting the cabinet,
S
making ground and all power connections,
S
powering up the cabinet (system power‐up),
S
mounting any customer‐supplied equipment inside the cabinet,
S
making communication cable connections,
S
making any desired alarm connections,
S
optioning the installed equipment and placing it in service, and
S
performing cabinet housekeeping, and closing and locking
the cabinet.
The following paragraphs provide detailed instructions for
performing these procedures.
3.1
Inspecting the Equipment
‐ DESICCANT NOTE ‐
To prevent condensation during shipment and storage, Westell
includes a desiccant pack within the Boxer cabinet. Once the
electronic equipment is installed and turned‐up, the internal
power dissipation reduces the likelihood of condensation within
the cabinet. However, follow company practices for desiccant
maintenance procedures to prevent internal condensation.
‐ INSPECTION NOTE ‐
Visually inspect the unit for damages prior to installation. If the
equipment was damaged in transit, immediately report the dam
age to the transportation company and to Westell (see Part 6).
