‐ FAN WIRING IN EURO‐CONNECTOR NOTE ‐
One euro‐connector serves two fans: there is one connector for
the two external air fans (connector labeled “FAN A”) and one
connector for the two internal air fans (“FAN B”). Each fan has
a black wire and a red wire. When wiring a new or replacement
fan, the same colored wire from each fan should first be twisted
together as a single wire unit prior to insertion into its proper
termination hole in the connector.

Apply power and test.
If not already installed, re‐install the
fuse in the controller card, and apply power to the cabinet.
Verify the fans are working properly.

Replacing the Door Alarm Sensor
Door alarm sensor switch cannot be field repaired. Should a
problem be suspected with the door alarm, remove the entire
door alarm switch assembly and return it to Westell for service,
then replace it. To remove and replace the door alarm switch
assembly, proceed with the following instructions.
‐ WIRE AND BLOCK DISCONNECTION NOTE ‐
The Euro‐connector blocks used for making DC distribution and
alarm wire connections facilitate a simple group disconnection of
all alarm and dc distribution wire connections; there's no need to
unscrew each wire. Simply remove the entire block by pulling the
blocks away from the panel.
‐ CAUTION ‐
To avoid electrical shock, turn off any DC or AC power feeds
to the controller before beginning this procedure.

Open the cabinet door if accessing the
door switch from the front; if accessing the switch from the
rear, remove the rear access panel.

Disconnect the door alarm switch
power by removing the door alarm Euro connector at the
bottom of the controller card.
3.
Remove door switch assembly.
Remove the door alarm
switch with a flat screwdriver by snapping/prying it out of
the bracket which houses it.
4.
Disconnect wires at door switch.
Carefully disconnect each
wire from the switch, noting which terminal was used and
labelling the color or polarity of each connector, for easy re‐
connection to the new door switch assembly.
5.
Wire then install the new switch into the mounting bracket.
Connect the wires into their proper positions in the new
switch.
Insert the new door sensor assembly into its mount
ing bracket from the rear side so the door sensor button

ing bracket; press or snap it into place.
