De-energize main feed to the dimmer rack and follow appropriate
Lockout/Tagout procedures as mandated by NFPA 70E. It is
important to note that electrical equipment such as dimmer racks
can present an arc flash hazard if improperly serviced. This is due to
the high amounts of short-circuit current available on the electrical
supply to this equipment. Any work must comply with OSHA Safe
Working Practices.
