User's Manual Pub. 0300321-01 Rev. A
You can install the module on DIN rails of dimension 35 mm × 7.5 mm × 1 mm
(EN 50 022-35×7.5), or on a panel.
Hazard of intermittent grounding.
This product is grounded through the DIN rail to chassis ground. To
assure proper grounding, use zinc-plated, yellow-chromate steel DIN
rail. Using other DIN rail materials such as aluminum or plastic, that
can corrode, oxidize, or are poor conductors, may result in improper
or intermittent grounding.
Use the correct DIN rail type, and secure DIN rail to mounting surface
approximately every 200 mm (7.8 in.) and use end-anchors appropriately.
1. Before mounting the module on a DIN rail, use a flat-bladed screwdriver
in the DIN rail latch and pry it downwards until it is in the unlatched
position.
2. Hook the top of the DIN rail mounting area of the module onto the DIN
rail, and then press the bottom until the module snaps onto the DIN rail.
3. Push the DIN rail latch back into the latched position. Use DIN rail end
anchors for vibration or shock environments.
4. Snap the module into the module bay.
Using a screwdriver, tighten the 10...12 mm (0.39...0.47 in.) M3 self-

tapping screw to torque specifications: 0.25 N-m (2.2 lb-in).
Panel Mounting
The preferred mounting method is to use two M4 (#8) screws per module. Hole
spacing tolerance is ±0.4 mm (0.016 in.). For mounting dimensions, refer to
Micro830, Micro850, and Micro870 Programmable Controllers User Manual
2080-UM002.
To install:
6. Place the module next to the controller against the panel where you are
mounting the module.
7. Mark drilling holes through the mounting screw holes and mounting feet,
and then remove the module.
8. Drill the holes at the markings.
9. Replace the module and mount it. Leave the protective debris strip in
place until you are finished wiring the module, and any other devices.
