Installing the Modules
Mount Modules with Screws
The steps in these instructions show how to mount the modules on DIN rail.
If you are using screws instead of DIN rail, make these changes to the
instructions.
1. Follow the steps in Mount the Module on the DIN Rail on page 10 to
connect the modules together.
2. Use the modules as a template and mark pilot holes on your panel.
3. Drill the pilot holes for M4 or #8 screws.
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 (7.87 in.)
and use end-anchors appropriately.
IMPORTANT
Do not use screws and DIN rail to mount the modules. It is possible
to break the mounting tabs off if you screw the modules to the panel
while they are on DIN rail.
ATTENTION
Do not let metal to fall into modules while drilling. This could damage
the modules.
