3-18 Receiving & Installation
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.
Terminal connections for DB hardware is determined by the control model number suffix
(E, EO, ER or MO). See Figure 3-18 for terminal identification. Refer to Tables 3-6 and
3-7 for wire size information.
Note:
Although not shown, metal
conduit should be used to shield all
power wires and motor leads.
