Install the CompactLogix 5370 L2 Controller Chapter 3
5. Place the modules back on the panel and check for proper hole
alignment.
6. Use the mounting screws to attach the modules to the panel.
7. Repeat steps 1
…6 for any remaining modules.
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.
TIP The grounding plate, that is, where you install the mounting screws,
grounds the module when it is panel-mounted.
TIP If you are mounting more modules, mount only the last one of this
group and put the others aside. This process reduces remounting time
when you are drilling and tapping the next group of modules.
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.
