The 2030FBC UniModule is 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-273-2)
For These UM FBC Combinations Use These
Installation Steps:
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 1020FBC UniModule is designed to mount
to the face of a C-Face motor as noted in
Table 1.

Mounting to a C-Face Motor
1. A hardened key is provided with the
mounting hardware for FBC UniModules.
Insert this key onto the motor shaft
(staking the key is necessary).
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 2.
alternately to ensure even alignment of the
module. Tighten them to 30-35 foot
pounds.
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.
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.
Figure 2
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 3a)

socket, tighten the two (2) setscrews
to: (Figure 3b)
• Size 50: 80-85 inch pounds
(Requires 5/32 inch Allen wrench)
• Size 100 or 180: 40-45 inch pounds
(Requires 1/8 inch Allen wrench)
3. Secure the FBC UniModule to the motor
with the four (4) long mounting tie-bolts
provided. Tighten the four (4) bolts
