Installation
Basic Installation Notes
You are required to follow all safety precautions during start-up such as providing proper
equipment grounding, correctly fused power and an effective Emergency Stop circuit which
can immediately remove power in the case of a malfunction. See the “Safety Considerations”
section for more information.
Mechanical Installation
The FM-3 module detects and verifies the drive serial number when its attached to an drive.
If a FM-3 module is moved from one drive to another, it will detect the difference in serial
numbers and generate an Invalid Configuration fault.
Two aligning tabs, a locking latch and a 100-pin connector are used to attach the FM-3
module to an EN drive. All electrical connections between the FM-3 module and the EN drive
are accomplished with the single connector located on the rear of the FM-3 module.

Do not attach or detach the FM-3 module when power is applied to the drive. It could
cause drive instability.
