Power+™ Control Units
Chapter 1. Introduction
1–1 Applications
The Power+™ Control Units described in this publication
are used on Power Break® II insulated-case switches.
1–2 General
Power+ Control Units are the same size and have the same
connectors as the Power+ trip units and the RMS9D series
of MicroVersaTrip Plus™ and MicroVersaTrip PM™ trip
units.
Power+ Control Units may be tested with the Control Unit
installed in the switch, the rating plug installed in the
Control Unit, and the switch carrying current. The Test
Kit plugs into the test socket of the rating plug. The Test
Kit catalog number is TVRMS2 and its operation is
described in GEK–97367.
Power+ Control Units are removable from the switch. For
instructions on installing and removing the Control Unit,
see Chapter 4 of this guide or the appropriate switch
user’s guide.
CAUTION: Removal of a Control Unit from its switch
must be performed with the switch in the OPEN or
TRIPPED position. Draw-out switches should be racked
out first.
ATTENTION: Pour retirer unité de contrôle,
l'interrupteur doit être en position ouverte ou
déclenchée. Les interrupteurs débrochables doivent ètre
en position débrochée.
CAUTION: Do not attempt to operate the switch without
its assigned Control Unit. Installation of an incorrect
Control Unit may result in unsafe operation of the
switch.
ATTENTION: Ne pas tenter d'opérer l'interrupteur sans
son unité de contrôle assignée. L'installation d'une unité
de contrôle incorrecte peut avoir comme conséquence
une opération non sécuritaire de l'interrupteur.
NOTE: Control Units as received may have settings that
are undesirable for the specific application. Ensure that
settings are appropriately adjusted before energizing.
NOTE: Unités de contrôle sont livrés avec des réglages
standards qui peuvent être inadéquates pour certaines
applications. Vérifier ces réglages avant de mettre le
disjoncteur sous tension.
