Switch Input Grounding
The Switch Input circuits are functionally isolated from other circuits. It is
recommended that the Switch RTN signal be grounded at a single point.
Connect the Switch RTN signal to the XM terminal base (Chassis terminal) or
directly to the DIN rail, or ground the signal at the switch or other equipment
that is wired to the switch.
Mounting the Terminal
Base Unit The XM family includes several different terminal base units to serve all of the
XM modules. The XM-940 terminal base, Cat. No. 1440-TB-A, is the only
terminal base unit used with the XM-123 module.
