Installation Instructions
A. Installing the Conduit Box
Please follow instructions supplied with conduit
box.
B. Mounting the Magnet
The brake magnet is mounted to a stationary
machine member by a flange. Extreme care
must be taken in selecting the location for the
mounting of the magnet. Proper positioning is
very important for the unit to function correctly.
1. A pilot diameter on the mounting surface is
essential to hold the magnet within the
required tolerances. (Figure 1)
2. A machined pilot diameter is provided on the
magnet mounting flange (refer to illustrations)
to aid in the proper positioning of the magnet.
3. Once the mounting surface has been
prepared, the magnet is bolted in place
with capscrews and lockwashers. (Figure 2)
