National Electrical Manufacturers Association (NEMA)
standards . They can be mounted to common NEMA
C-frame motors and reducers as well as common
power transmission drive components .
The 10-20, 10-20FBC, 20, 20FBB, and 10-40
Electro-Modules are designed to mount to the face
of a C-frame motor as noted in Table 1 .

Table 1
The 20-30, 20FBC-30 and 30-40 Electro-Modules
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-bolts, chain and sprockets, couplings, timing belts
and other standard power transmission components .
The 20FBC series of Electrically Released Brake
Modules are designed to be used in clutch-brake
combinations . The FBC modules can be mounted on
a C-face motor with a (10) input clutch module and
can also be foot mounted with a (30) input clutch
module and base .
The 20FBB series of Electrically Released Brake
Modules are designed to be mounted on the front of
a C-faced motor as a brake only .
The Fail Safe (FBB & FBC) brake engages when the
power goes off .
(For Electro-Module sizes 210 and 215 please refer
to Warner Electric manual P-213 .)
Install your specific Electro-Module combination
according to the installation steps specified in
Table 2 . Use only those steps indicated for each
combination .
