6 Installing the XM-120 Eccentricity Module
XM Installation
Requirements This section describes wire, power, and grounding requirements for an XM
system.
Wiring Requirements
Use solid or stranded wire. All wiring should meet the following specifications:
• 14 to 22 AWG copper conductors without pretreatment; 8 AWG
required for grounding the DIN rail for electromagnetic interference
(emi) purposes
• Recommended strip length 8 millimeters (0.31 inches)
• Minimum insulation rating of 300 V
• Soldering the conductor is forbidden
• Wire ferrules can be used with stranded conductors; copper ferrules
recommended
Power Requirements
Before installing your module, calculate the power requirements of all modules
interconnected via their side connectors. The total current draw through the
side connector cannot exceed 3A. Refer to the specifications for the specific
modules for power requirements.
Figure 2.1 is an illustration of wiring modules using separate power
connections.
ATTENTION
See the XM Documentation and Configuration Utility CD
for Hazardous Locations installation drawings. The XM
Documentation and Configuration Utility CD is packaged
with the XM modules.
ATTENTION
A separate power connection is necessary if the total
current draw of the interconnecting modules is greater than
3 A.
