READ AND UNDERSTAND THIS BOOKLET IN ITS
ENTIRETY BEFORE INSTALLING OR OPERATING
CONTROLLER. INSTALLATION, ADJUSTMENT, REPAIR
AND MAINTENANCE OF THESE CONTROLLERS MUST
BE PERFORMED BY QUALIFIED PERSONNEL. A
QUALIFIED PERSON IS ONE WHO IS FAMILIAR WITH
THE CONSTRUCTION AND OPERATION OF THIS
EQUIPMENT AND THE HAZARDS INVOLVED.
THE CONTROLLER
Each Ampgard ® motor starter (controller) consists of one
nonload-break isolating switch, one or more Type SJS,
NEMA Size H6, vacuum-break contactors, current-limiting
fuses, a set of current transformers, and some form of
overload protection. The isolating switch has a limited
make and break rating, suitable only for closing and
opening limited magnetizing current loads. The controller is
designed to start, stop and protect a three-phase medium-
voltage motor within the ratings shown in Table I. The
controller may also be used to switch transformer windings
or capacitor banks. Each Ampgard
® controller occupies all
or a portion of a steel structure that may also enclose a
horizontal bus system to distribute power to two or more
sections and a vertical bus system in each section con-
nected to the horizontal main bus system. The controllers
are configured for full-voltage or reduced-voltage starting,
reversing or nonreversing, single-speed or two-speed
applications.
