WARNING – Bodily injury. Do not separate when energized, this
applies to all connectors and connections.
Make sure there is no hazardous atmosphere present when performing
maintenance on the unit.
Field wiring cables and wires can be energized from optional power
sources other than the RMC. Disconnecting energized cabling or wiring
would cause a spark that would ignite a hazardous atmosphere if
present.
WARNING – Equipment damage. Potential electrostatic charging
hazard: clean only with damp cloth
