3-20 Receiving & Installation
MN715
Optional Dynamic Brake Hardware
Dynamic Brake (DB) Hardware must be installed on a flat, non-flammable, vertical
surface for effective cooling and operation. Refer to MN701 (for RGA, RBA and RTA
assemblies) or MN782 (for RUA assemblies) for additional information.
Electrical Installation
Terminal connections for DB hardware is determined by the Control model number suffix
(E, EO, ER or MO). See Figure 3-19 for terminal identification. Refer to Tables 3-8 and
3-9 for wire size information.
