Installation
Installing a 45M Module on a DIN Rail
Step 1: Align the 45M module side by side with the head/CPU module, making sure that the upper and lower rails are hooked together.
Step 2: Align the 45M module side by side with the head/CPU module and then push the 45M module until it touches the DIN rail.
- 2 -
Next, apply more force until the module clips to the DIN rail.
NOTE After the module is firmly attached to the DIN rail, the module connections to the internal bus will be established.
Removing a 45M Module from a DIN Rail
Step 1: Use your finger to lift the release tab on the lower part of the module.
Step 2: Push the top of the release tab to latch it, and then pull the module out.
NOTE Electrical connections for the internal bus will be disconnected when removing the 45M module.

WARNING
Be sure the power is off before removing modules to avoid damaging the equipment.
Installing the Covers on the First and Last Module
Attach the covers to the first and last module to cover the modules' contacts.
NOTICE
Be sure to attach the covers to provide electrostatic discharge protection.
Horizontal Installation
Before installing the device, make sure there is enough space between the device and nearby items
(walls, other devices, etc.) to ensure proper heat dissipation.
To ensure that the device works properly, we suggest reserving the amount of space indicated in the adjacent figure.
