Introduction
This instruction book is intended to cover
the handling, installation, operation, and mainte-
nance of AMPGARD
T
400A, 7.2 kV starters and
associated equipment. The function of these
controllers is to start, stop, and protect medium
voltage motors, transformers, capacitors, and
other loads. Controllers may be of full voltage,
reduced voltage reactor, reduced voltage
autotransformer, reduced voltage solid-state, or
two-speed type. They may control induction or
synchronous machines, and they may be
non-reversing or reversing.
While this instructional leaflet is dedicated primarily
to full-voltage starting, the other applications listed
are an expansion of the principles identified in this
leaflet. This leaflet does not purport to cover all
possible contingencies, variations, and details that
may arise during operation or maintenance of this
equipment. If further information is desired
regarding this product, contact your local Eaton
sales office.
Identification
A rating nameplate is located on the door of each
controller. Contained on this nameplate are the
controller type and ratings as required by industry
standards. Also contained on this nameplate is the
factory’s general order number. This number should
be given to the Eaton sales office if a question
should arise concerning the equipment or if renew-
al parts are required. Refer to
Figure 1
for typical
location of rating nameplates.
