Chapter 2 Installation Instructions
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 1.72”(51
mm).
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 1.72”(51mm) behind the panel.
NEMA-4
Mounting
Put the unit through the panel cut out. Slide the clamps into the 6
holes provided around the case. Tighten the clamping screws in an
even pattern until the unit is secured in the panel.
Caution! Do not over tighten mounting clamps!
Note: Specifications Note:
To seal to NEMA-4 specifications, all supplied mounting clamps
must be used and panel cannot flex more than 0.010”.
