Preparation
1:

.
2:
Turn off main power to the enclosures.
3:
Remove the eight dimmer modules above the CEM+ (if retrofitting an SR+48 rack, remove the
eight modules below the CEM+ as well). Note and document the modules’ order/positioning in
the enclosure for proper insertion and configuration later.
4:
Use a digital voltmeter and VERIFY that power is off by checking voltages for all combinations
between the phase bars, neutral and ground.
5:
Remove the CEM+ from the rack.
WARNING:
RISK OF DEATH BY ELECTRIC SHOCK! Power down the rack before
removing the CEM3. 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 CEM3. 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 DEATH BY 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.
