ATTENTION

Remove power before removing or inserting this module. When

you remove or insert a module with power applied, an electrical

arc may occur. An electrical arc can cause personal injury or

property damage by:

• se

nding an erroneous signal to your system’s field devices,

causing unintended machine motion

• cau

sing an explosion in a hazardous environment

Electrical arcing causes excessive wear to contacts on both the

module and its mating connector. Worn contacts may create

electrical resistance.

ATTENTION

When attaching I/O modules, it is very important that the bus

connectors are securely locked together to ensure proper

electrical connection.
