Panel Mounting
The preferred mounting method is to use two M4 (#8) per module. Hole spacing tolerance:
±0.4 mm (0.016 in.). For mounting dimensions, refer to Micro830 and Micro850
Programmable Controller User Manual, publication
.
Follow these steps to install your module using mounting screws.
1. Place the module next to the controller against the panel where you are mounting it.
Make sure the controller and module are spaced properly.
2. Mark drilling holes through the mounting screw holes and mounting feet then remove
the module.
3. Drill the holes at the markings, then replace the module and mount it.
Leave the protective debris strip in place until you are finished wiring the module and
any other devices.
System Assembly
The Micro800 expansion I/O module is attached to the controller or another I/O module by
means of interconnecting latches and hooks, as well as the bus connector. The Micro850
controller and expansion I/O modules must terminate with a 2085-ECR Bus
Terminator module.
Be sure to lock the module interconnect latches and tighten the RTB hold down screws before
applying power to the module.
For installation of the 2085-ECR module, refer to Micro800 Bus Terminator Module
Installation Instructions, publication
.
Field Wiring Connections
In solid-state control systems, grounding and wire routing helps limit the effects of noise due to
electromagnetic interference (EMI).
ATTENTION: Failure to connect a bus terminator module to the last expansion I/O module will
result in a controller hard fault.
ATTENTION: Do not wire more than 2 conductors on any single terminal.
