W A R N I N G :
Dimmer racks without an accessible power disconnect device cannot be
serviced safely. Before removing dimmer or control modules for service, 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.
