XM-440 Master Relay Module
Mount the Module
The XM® 440 module mounts on a XM-942 terminal base unit, catalog number 1440-TB-C. We recommend that you
mount the module after you have connected the wiring on the terminal base unit. Refer to the XM-942 Master Relay
Terminal Base Installation Instructions, publication
GMSI10-IN022 .
1. Make certain the keyswitch (A) on the terminal base unit (C) is at position 2 as required for the XM-440 module.
2. Make certain the side connector (B) is pushed all the way to the left.
You cannot install the module unless the connector is fully extended.
3. Make sure that the pins on the bottom of the module are straight so they align properly with the connector in the
terminal base unit.
4. Position the module (D) with its alignment bar (E) aligned with the groove (F) on the terminal base unit.
5. Press firmly and evenly to seat the module in the terminal base unit.
The module is seated when the latching mechanism (G) is locked into the module.
6. Repeat the above steps to install the next module in its terminal base unit.
All grounds in the system must be tied to the same point of the same grounding electrode system.
Maintain a 2.54 cm (1 in.) minimum clearance between the module and adjacent equipment. There are no orientation
restrictions.
The XM-440 module is compatible only with the XM-942 terminal base unit. Verify that the keyswitch on the terminal base unit
is at position 2 for the XM-440 module.
Do not attempt to install XM-440 modules on other terminal base units.
Do not change the position of the keyswitch after wiring the XM-942 terminal base unit.
