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.
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 furnished 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:
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:
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.
