Installation Instructions
1. Review the selection procedure on page 5 to
determine if the selected Washdown
Electro-Pack (EP-W) is the appropriate size
and voltage for the intended application.
2. Identify the input end of the EP-W by locating
the word "INPUT" cast into the side of the
housing.
3. Mount the EP-W to a rigid surface that is flat
within the following tolerances. Position the
input end toward the intended drive system
input.

250
.004"
400
.004"
4. Attach the drive system hardware to the input
and output shafts of the EP-W. Be sure to
connect the power input to the input shaft of
the unit. Serious system damage may occur if
the power input is connected to the EP-W
output shaft. See page 5 for shaft
dimensions.
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.

1. Remove the four screws and cover from the
top of the EP-W to gain access to the
electrical terminals on the clutch field and
brake magnet. (Figure 1)
2. Feed lead wires through one of the two 1/2"
conduit holes in the side of the EP-W housing.
3. Using the provided wire terminals, make the
proper electrical connections between the EP-
W and a suitable DC power supply. Refer to
Figure 2 for typical EP-W connections. Polarity
is not important when wiring Electro-Pack
units.
Warner Electric offers a full line of AC input, DC
output controls to meet the needs of most
clutch/brake applications. The service and
installation instructions included with each control
show the proper connections.

4. Replace the cover and four screws.
Burnishing
To obtain optimum Electro-Pack performance, a
wear-in process called burnishing is required
between the clutch and brake friction faces within
the unit. Warner Electric Electro-Packs are
burnished at the factory, eliminating the need to
burnish the unit upon installation.
Maintenance
Properly applied and installed Electro-Packs do
not require service, lubrication, or maintenance.
The Washdown EP is designed to withstand
limited exposure to high ambient temperatures
and high-pressure wash systems, however
optimum appearance and wear life will be
obtained if this type of exposure is minimized.
