WARNING:
To avoid the possibility of electric shock, power must be turned OFF before
removing dimmer or control modules. Prior to any action that involves
removing any module, de-energize main feed to dimmer rack and follow
appropriate Lockout/Tagout procedures as described in NFPA Standard 70E.
It is important to note that electrical equipment such as dimmer racks can
present an arc flash safety hazard if improperly serviced. This is due to
available large short circuit currents on the feeders of the equipment. Any
work on energized equipment must comply with OSHA Electrical Safe
Working Practices.
Phase voltages inside the rack can be deadly, therefore only qualified
technicians should be allowed to remove modules and expose the inside of
the dimmer rack.
