Installation & Operation Guidelines
-
Modules must not be inserted or removed in hazardous areas while system power is on. Only one module should be replaced at a time.
-
Non-sparking field circuits must be de-energized prior to insertion/removal.
-
A rotary keying system ensures correct matching between I/O cards and terminal blocks.
-
The module contains no user-serviceable parts and does not require calibration. Disassembly is prohibited.
Applications
