flat washer. Alternately, if the panel has a ground stud, use a nut and star lock washer for
each wire on the ground stud to ensure adequate grounding. Where connections are made

connection point. Terminals and hardware used should be rated to work with the aluminum

Unsupported Modules

CAUTION
If an unsupported module is inserted in the CEP or CEE Carrier, the module will not be
recognized correctly and could cause damage to the Carrier or the module.
When an unsupported I/O module is inserted in either the RX3i CEP Carrier or RX3i CEE
Expansion Carrier, no alarm is reported to indicate this.
Some unsupported I/O modules have the same Distinguishing Class (for example,
IC694MDL740 has the same Distinguishing Class as IC694MDL742). Refer to Section 1.6,
Supported I/O Modules.
Installation & Mounting
The star lock washer method is suitable for a shield ground, but not suitable for a safety
ground.
