Changing Installation Rack Modules
All Sensor+ rack dimmer modules can be easily replaced without tools. Modules slide in and out of
their slots and are ready to start dimming immediately.
Although Sensor modules, including the CEM+, can be replaced with power on, always turn rack
power off at the main circuit breaker, if possible, before changing modules.
WARNING:
RISK OF ELECTRIC SHOCK! Power down the rack before removing the
CEM+. Only remove modules with the rack powered off, following
these instructions or as instructed by ETC Technical Services.
AVERTISSEMENT :
RISQUE DE MORT PAR ÉLECTROCUTION! Mettez le rack de gradation
hors tension avant de retirer le CEM+. Ne retirez les modules de
gradation ou de contrôle que lorsque le rack est éteint, en suivant ces
instructions ou selon les instructions des services techniques ETC.
Removing modules exposes the phase bars inside of the rack. When the
rack is powered on, phase voltages inside the rack can cause injury or
death. When the rack is powered on, modules should only be removed
by qualified installers or electricians.
WARNING:
RISK OF ELECTRIC SHOCK! Failure to disconnect all power to the dimmer
rack before working inside could result in serious injury or death.
AVERTISSEMENT :
RISQUE DE MORT PAR ÉLECTROCUTION! Travailler à l’intérieur du rack
de gradation sans avoir déconnecté le courant peut entrainer des
blessures graves, voire mortelles.
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.
