MCH Spring-Charging Motor

X X UC4 External Phase Voltage Sensing

NOTE: When communication version of the MX1 or XF coils are used, terminals (C3,

A3) must be connected to line even if the communications module is not installed.

The bypass circuit through terminal C2/A2 is only momentary duty for 0.5 sec. For

continuous duty, use the communications command.

Figure 19: Connection of the Communications Option

NOTE: A recommended wiring schematic for the

communicating style shunt trip or shunt close coils is

shown below.

Induced voltages in the circuit at terminal C2 and/or

A2 can cause the shunt trip or shunt close to not work

properly. The best way to prevent the induced

voltages is keep the circuit to terminal C2 and A2 as

short as possible. If it is impossible to keep the circuit

less than 10 feet (3 m), use an interposing relay near

terminal C2 or A2.
