Installation Guidelines

Mount the unit on a 35 mm DIN rail (EN 60715) and engage the locking mechanism for a secure fit.
Ensure the use of shielded Cat.5 (or better) Ethernet cabling for the 100BASE-TX interface to prevent EMI.
Use the direct plug-in technique for solid conductors, or a screwdriver for spring-actuation with stranded wires.
Maintain the total power contact load (Imax) below 10 A.
Operating in an IP20-rated environment is required; ensure the installation location provides adequate protection against contaminants and moisture.
