RISK OF ELECTRIC SHOCK! Enclosures without an accessible power disconnect
device cannot be serviced safely. Before removing dimmer or control modules
for service, de-energize main feed to enclosure and follow appropriate
Lockout/Tagout procedures as described in NFPA Standard 70E. It is
important to note that electrical equipment such as enclosures 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.
