20 Installing the XM-160/161/162 Direct Vibration Module
Connecting the Power Supply
Power supplied to the module must be nominally 18–32 Vdc and must be a
Class 2 rated circuit.
Wire the DC-input power supply to the terminal base unit as shown in Figure
2.8.
Figure 2.8 DC Input Power Supply Connections
ATTENTION
If the power supply is mounted remotely from the module
rack, or the 24V power is sourced from something other
than an approved AC-DC power supply, a line filter must
be installed in series with the 24V source and the following
should be met:
• The total cable length should be less than 10m from the
24V source. Or,
• The cable should be shielded with the shield earth
grounded.
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 37 (+24 V In) to
provide power to the device and other XM modules linked
to the wired terminal base via the side connector.
