Install the CompactLogix 5370 L2 Controller
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.
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.
