Mounting And Demounting - ABB AC500 V3 Hardware Manual

2.6.3 Mounting and demounting

The control system is designed to be mounted to a well-grounded mounting surface such as a
metal panel. Additional grounding connections from the mounting tabs or DIN rail (if used), are
not required unless the mounting surface cannot be grounded.

During panel or DIN rail mounting of all devices, be sure that all debris (metal
chips, wire strands, etc.) is kept from falling into the controller. Debris that falls
into the controller could cause damage while the controller is energized.
All devices are 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.
Mount DIN rail 7.5 mm or 15 mm.
Mount the terminal base/function module terminal base:
ð The terminal base is put on the DIN rail above and then snapped-in below.
