DIGITMR S2 PC USER’S MANUAL REV 1

2.3.2. Initiate Cable Connections

The DigiTMR S2 PC will trip or close breakers through a solid-state device which will operate on

any AC or DC control voltage ranging from 10 to 300 Volts. Both the trip and close circuits are

protected by 5-Ampere fuses. A typical DC trip and DC close control circuit test connection is

shown in Figure 3. A typical DC trip and AC close control circuit is shown in Figure 4.

NOTE

Always connect the initiate circuit with an auxiliary switch in series. The auxiliary

switch provides the coil current interruption. Failure to follow this recommendation

will damage the DigiTMR S2 PC initiate circuit.
