T
he Warner Electric ERS brake you purchased has been designed to provide long and trouble free
service. It’s a rugged, simple unit which is easy to install and requires no adjustment or maintenance.
This service manual includes detailed installation instructions, complete product dimensions,
performance data, and troubleshooting information.
Installation
1. Remove your ERS brake from its shipping
carton and inspect it thoroughly to ensure
that it has arrived in good condition. An
accessory kit included with your brake
contains screws and insulator boots for the
electrical termination. In addition, you may
have ordered the optional splined drive hub,
mounting flange, and/or conduit box.
2. If used, install the Warner Electric conduit
box in accordance with the instructions fur-
nished with the conduit box accessory.
3. The ERS brake is shipped fully assembled
and ready to mount. No adjustments or
brake run-in are necessary. The mating
mounting holes in your mounting surface
must be within 0.014 inch diameter of true
position to the shaft center line and the
mounting surface must be within .005” of
perpendicular to the shaft axis. If you are
mounting your brake with through-bolts (see
Mounting Options below) you will need four
of the following fasteners:
Maximum
Brake Fastener Size Fastener Torque
ERS-26 #6-32 20 in.lbs.
ERS-42 #8-32 35 in.lbs.
ERS-49 #10-32 75 in.lbs.
ERS-57 1/4”-20 120 in.lbs.
ERS-68 3/8”-16 150 in.lbs.
Through-Bolt
Mounting through the brake
magnet provides rigid
support for the unit with a
space equal to the outside
diameter of the brake. May
be mounted on either end.
Your ERS Brake is designed to
self-engage in case of an electrical power
failure. Replace only with an identical unit.
Do not disassemble. Brake parts are under
high spring pressure. Failure to follow these
instructions may result in product damage,
equipment damage, and serious or fatal
injury to personnel.
If the optional Warner Electric mounting flange is
being used, assemble with the supplied screws
into the tapped holes in the back of the brake.
You will need to provide a mounting hole pattern
in the flange that corresponds to your application.
Brake Mounting Options
ERS Brakes can accommodate different mounting
orientations. The following mountings are possible
with the standard ERS brake:
