before or after mounting. For mounting instructions, see “Panel Mounting”
on page 6, or “DIN Rail Mounting” on page 7. To work with a system that

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:
• sending an erroneous signal to your system’s field
devices, causing unintended machine motion
• causing 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.
