Environment and Enclosure This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 meters without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11. Without appropriate precautions, there may be potential difficulties ensuring electromagnetic compatibility in other environments due to conducted as well as radiated disturbance. This equipment is supplied as "open type" equipment. It must be mounted within an enclosure that is suitably designed for those specific environmental conditions that will be present and appropriately

FAQs

What are the key installation steps for HM1734-WM-2HR?

The manual describes mounting, mechanical keying, wiring base assembly setup, removable terminal block (RTB) use, module locking, and DIN rail mounting with the appropriate locking screw and side pieces. It also references the module wiring diagram for connection planning.

What enclosure and environmental conditions does the module require?

Use the equipment in a Pollution Degree 2 industrial environment and overvoltage Category II applications, at altitudes up to 2000 meters without derating. Mount it as “open type” equipment inside an enclosure designed to prevent access to live parts using tools only.

How should grounding and electrostatic discharge (ESD) be handled?

POINT I/O is grounded through the DIN rail to chassis ground; use zinc plated, yellow chromated steel DIN rail to ensure proper grounding. The equipment is sensitive to electrostatic discharge, so discharge static by touching a grounded object and follow safe handling guidance.
