Removing the shutter unit
Refer to DEH-41696 for full instructions on the
removal of the shutter unit.

Warning: Unless the proper precautions are
taken, the removal of a shutter unit presents
the hazard of electrical shock and burn.
Do not remove the shutter unit unless the
equipment has been deenergized. Failure
to do this can result in serious injury.

Avertissement: Si les précautions
requises ne sont pas prises, le retrait d'un
obturateur présente un risque de choc
électrique et de brûlure. Ne retirez pas
l'obturateur, sauf si l'équipement n'est
plus alimenté. Vous courez sinon le
risque de vous blesser gravement.

Installing the shutter unit
Refer to GEH-41696 for full instructions on
installation of shutter units. Available shutter
units are listed below on the table listing
available catalog numbers.

Warning: Unless the proper precautions
are taken, the installation of a shutter unit
presents the hazard of electrical shock and
burn. Do not install the shutter unit unless
the equipment has been de-energized.
Failure to do this can result in serious injury.

Avertissement: Si les précautions
requises ne sont pas prises, l'installation
d'un obturateur présente un risque de choc
électrique et de brûlure. N'installez pas
d'obturateur, sauf si l'équipement n'est plus

vous blesser gravement.

Padlocking the cassette
The circuit breaker compartment door must be
opened to put the padlock on; however, there is no
interference with the door after the padlock has
been placed in position. Padlocks will prevent the
acceptance of breakers in the cassette. The padlock
device on the cassette will accept up to three
padlocks on both the left and right sides of the
cassette. See Fig. 7.9.

Padlocking the shutter
The shutter on each cubicle can be padlocked to
prevent access to the live primary conductors.
The shutter can be padlocked without the breaker
installed. One padlock can be placed on a cassette.
To padlock shutter, pull out the shutter locking tab
and insert padlock, see Fig 7.10. Pulling out the
shutter locking tab actuates a rod that goes
through moving shutter parts that prevents it
from opening.
