Wiring Requirements
Use solid or stranded wire. All XM wiring must meet the following
specifications:
• 2.1…0.34 mm² (22…14 AWG) copper conductors without
pretreatment; 8.4 mm² (8 AWG) or 1 in. copper required for
grounding the DIN rail for electromagnetic interference (EMI)
purposes
• Recommended strip length 8 mm (0.31 in.)
• Minimum insulation rating of 300V
• Soldering the conductor is forbidden
• Wire ferrules can be used with stranded conductors; copper ferrules
recommended
Grounding Requirements
Follow these grounding requirements to be sure of safe electrical operating
circumstances and to help avoid potential EMI and ground noise that can
cause unfavorable operating conditions for your XM system.
DIN Rail Grounding
The DIN rail must be connected to a ground bus or grounding electrode
conductor using 8.4 mm² (8 AWG or 1 in.) copper braid. The grounding wire
can be connected to the DIN rail using a DIN Rail Grounding Block.
ATTENTION
This product is grounded through the DIN rail to chassis ground. Use zinc
plated yellow-chromate steel DIN rail to assure proper grounding. The use of
other DIN rail materials (for example, aluminum or plastic) that can corrode,
oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately.
