Mount the Controller on the DIN Rail
You can mount the controller on the following DIN rails:
• EN 50 022 - 35 x 7.5 mm (1.38 x 0.30 in.)
• EN 50 022 - 35 x 15 mm (1.38 x 0.59 in.)
1. Hook the DIN rail latch at the top of the back of the controller on the
DIN rail.
2. Swing the controller downward until it touches the DIN rail and press
the controller against the DIN rail until it clicks in place.
The click verifies that controller is locked on the DIN rail.
Ground the System
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.
ATTENTION: This product is intended to be mounted to a well-grounded mounting
surface such as a metal panel. Additional grounding connections from the power
supply's mounting tabs or DIN rail (if used) are not required unless the mounting
surface cannot be grounded.
