Entellisys Low Voltage Switchgear
Chapter 7. Operating the Switchgear
Care must be exercised when installing or removing phase
current transformer mounting screws so as not to strip the
holes in the plastic base. Do not torque screws over five
in/lbs.
Removing Shutter Units
Visual inspection of primary disconnects and CT's can be
made by first removing the breaker and opening the
shutters manually. This is done by pressing the left and
right hand actuating rollers toward the rear of the
compartment simultaneously. This is a two-handed
operation.
If it is necessary to perform work on the primary
disconnects or CT’s, it will be necessary to remove the
entire 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 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.
