Introduction to AC500
This product is grounded through the DIN rail to chassis ground. Use zinc
plated yellow-chromate stell DIN rail to assure proper grounding. The use of
other DIN rail materials (e.g. aluminium, plastic, etc.) that can corrode, oxidize,
or are poor conductors, can result in improper or intermittent grounding.
