IMPORTANT
A Class 2 circuit can be provided by use of an NEC Class 2
rated power supply, or by using a SELV or PELV rated
power supply with a 5 Amp current limiting fuse installed
before the XM module(s).
IMPORTANT
24Vdc needs to be wired to terminal 44 (+24 V In) to
provide power to the device and other XM modules linked
to the wired terminal base via the side connector.
IMPORTANT
When the XM-220 is used as part of an Electronic
Overspeed Detection System, redundant power may be
applied directly to the module per the XM Electronic
Overspeed Detection System User Guide, publication
GMSI10-UM015A-EN-E.
ATTENTION
The power connections are different for different XM
modules. Refer to the installation instructions for your
specific XM module for complete wiring information.
