Introduction
T
he Electro-Pack is a preassembled foot
mounted clutch-brake package complete with
input and output shafts. In the ceramic version,
the conventional friction material has been
replaced with ceramic material. In many high
cycle rate applications, the ceramic units will last
3-5 times longer than standard units. These
units, like the standard Electro-Packs, are ready
to be installed in all standard power transmission
systems with V-belts and pulleys, chain and
sprockets, in line couplings, timing belt drives,
and gear trains.
Installation
1. Provide a mounting surface for the
Electro-Pack that is rigid and flat with the
following tolerances.
Electro-Pack Mounting Surface to be
Sizes Flat in One Plane Within:
170 .004"
250 .004"
2. Connect the Electro-Pack into the drive
system. The input shaft is identified on the unit.
Use care when connecting the units!
Serious problems will occur if the power input
is connected to the output shaft.
Dimensions for the input and output shafts are
shown on the dimension drawings on page 5.
Electrical Connection
All electrical current must be off when
making electrical connections to prevent
injury or death which can result from contact
with live wires.
The Electro Pack is provided with one conduit
connection hole which is threaded for standard
1/2" conduit connectors. Both the clutch and
brake lead wires exit through this opening. The
EP-170-C is provided with lead wires already
routed through the conduit connection hole. The
EP-250-C is supplied with terminals that can be
accessed by removing the cover.
Simply make the connections with the terminal
accessory kit supplied.
Failure to follow these
instructions may result in product damage,
equipment damage, and serious or fatal
injury to personnel.
