Failure to follow these
instructions may result in product damage,
equipment damage, and serious or fatal
injury to personnel.
The equipment covered by
this installation manual must be installed in
accordance with these instructions. Failure
to do so may damage the equipment and
void the warranty.
Warner Electric UniModules are designed to
National Electrical Manufacturers Association
(NEMA) standards. They can be mounted to
common NEMA C-Face motors and reducers as
well as common power transmission drive components.
The 1020 and 1040 UniModules are designed to
mount to the face of a C-Face motor as noted in
Table 1.
The 2030 and 3040 UniModules are designed to
mount using a base mounting kit. This allows
the modules to be mounted as a separate drive
unit driven from the prime mover by V-belts,
chain and sprockets, couplings, timing belts and
other standard power transmission components.
(For UniModule sizes 210 and 215 please refer
to Warner Electric manual P-273-1)

Mounting to a C-Face Motor
1. A hardened key is provided with the
mounting hardware for UniModules.
Insert this key onto the motor shaft. It is
recommended to stake the end of the
motor shaft keyway to keep the key from
moving out during operation.
2. Align the keyway in the bore of the
UniModule to the key in the motor shaft
and slide the unit onto the motor shaft.
The normal alignment of the module to the
motor will be with the wire exit/conduit
box in the upright (12 o’clock) position as
shown in Figure 1.
Do not hammer or force the
module into position. To do so may damage
bearings or cause the friction faces to shift out
of alignment.
alternately to ensure even alignment of the
module. Tighten them to 30-35 foot
pounds.
Do not tighten the two (2) clutch
rotor set screws to the shaft before tightening
the four (4) module tie-bolts. This could cause
a preload on the pilot bearing resulting in
premature bearing failure.
4. Next secure the clutch rotor and fan
assembly to the motor shaft by tightening
the two (2) setscrew as follows:
a. There are two (2) access slots on
either side of the UniModule. A long
Allen wrench can be used to tighten
the two setscrews (90° apart) which
secure the clutch rotor and fan
assembly to the motor shaft.
b. Alternately align each setscrew with
one of the access slots by rotating the
clutch rotor and fan assembly through
one of the side vents with a small
screw driver taking care not to damage
the fan. (Figure 2a)

ensure that any excess is wiped off before unit
assembly to avoid lubricant contaminating the
clutch or brake friction faces.
c. Using a torque wrench and long Allen
socket, tighten the two (2) setscrews
to: (Figure 2b)
3. Secure the UniModule to the motor with
the four (4) long mounting tie-bolts
provided. Tighten the four (4) bolts
