Field Installation Guidelines
Ensure external power supplies are completely de-energized before connecting field wiring to the digital input and output terminals. Mount the module securely onto a standard DIN-rail or flat panel surface, maintaining adequate spacing for thermal dissipation within the operating temperature range of -25 deg C to +55 deg C. Verify proper shielding and termination of the 10BASE-T Ethernet cable to prevent electromagnetic interference in harsh industrial installations.
