Configuration A – Single-speed – 208 or 230 Volt Connections
Configuration A utilizes direct connection of a three-phase 208 or 230 volt main power supply to the hoist
motor leads via a terminal strip. A motor brake rectifier circuit board (ACF) is provided to operate the D.C.
hoist motor brake assembly.
Figure 2. Configuration A Connections
The SM1 three-phase motor is only available as a two-speed. Therefore, the above layout shows the
connection of the high-speed motor leads and motor brake coil leads to the ACF direct control board.
The connections are the same for both 208 Volts and 230 Volts. The brake coil supply voltage from the AFC
brake control card is 90 - 100 volts DC for both 208 Volts and 230 Volts.
