Installing an EntelliGuard G Shutter Unit (in a
de-energized cubicle)
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.
ADVERTISSEMENT: A moins que les précautions nécessaires
ne soient prises, l’installation d’une unité à volet présente des
risques de choc électrique ou de brûlure. Il ne faut pas
installer l’unité à volet à moins que l’équipement ait été
désamorcé. L’omission de ce faire peut résulter en blessures
sérieuses.
To install these shutter units, proceed as follows:
1. Carefully maneuver the shutter frame into the
compartment, first lifting it over the racking cams on
each side wall of the cassette. Make sure the shutter fits
over the shutter actuator at the bottom of the cassette.
2.
Position the shutter frame against the stab tip braces and
align the holes with the stand off on the braces.
3. After the holes are aligned with the threaded stand
offs, attach the shutter in 4 corner locations using
the bolts supplied.
4. Check the operation of the moveable shutters by
actuating the shutter level on the bottom of the cassette.
