2.1 Mounting Instructions
2.1.1 Location Considerations
Care should be taken when locating equipment behind the unit to ensure that AC power wiring, PLC output modules,
contactors, starters and relays, and any other source of electrical interference are located away from the back of the unit.
Particular note should be taken to the position of variable speed drives and switching power supplies. Their input and load
cables should be screened to a central star earth point.
2.1.2 Making a NEMA-4 Mounting
Panel
Details
The unit can be mounted into panels with a depth of 4”(105mm). It is recommended that the unit
be mounted on the front panel of a steel enclosure, through an appropriate opening*. Allow a
clearance of 1”(25mm) around the sides of the unit for mounting hardware. Allow clearance for
cable connections to the back of the unit. Unit depth may vary according to cable type used.
Typically, plan a depth to accommodate at least 3”(105mm) behind the panel.
Note:
Deburr and clean cutout before beginning installation.
