Main Circuit Breaker Protection
Before you begin installing the Unison ® external processing rack enclosure, make sure you
have installed a main circuit breaker cabinet or other readily accessible input power
disconnect device in the same, room or in close proximity to the installed ERn enclosure.
Lockout / Tagout
Equipment should have power disconnected and be locked out while being repaired.
Accidents which occur because equipment that is being repaired and not locked out can
result in serious injuries like amputations, fractures, and even death. Locking out and
tagging power at its source is important while repairing or adjusting equipment because it
ensures that power does not reach the equipment being serviced.
• To lockout means to place a lock on a device that prevents the release of energy.
Locking out is intended to prevent the unexpected startup or energizing of machinery
and equipment during service and maintenance operations.
• To tagout means to place a tag on a switch or other shut off device which warns others
not to start the piece of equipment. Tagout should only be used with lockout, unless
locking out the equipment is impossible.
W A R N I N G : Rack enclosures installed without an accessible power disconnect device
cannot be serviced or operated safely. Follow all local codes and
restrictions.
When the disconnect device is not located near the installed rack enclosure,
the disconnect must allow for proper lockout and tagout.
N o t e : While ETC does not intend to qualify your facility Lockout/Tagout procedures, we
have provided a generic guide below for your reference as needed.
