For regulator operation by +48 Vdc or 120 Vac remote control signals, rotary switch S1 must be set to REM. Remote control is disengaged when switch S1 is set to any position other than REM.

See Figure 2-4. Refer to Table 4-3 for setting up remote control.

To shut down the CCR, perform the following procedure:

1.See Figure 2-4. Set rotary switch S1 (6) to position OFF.

NOTE: Power to the output terminals (10) is now off, and the regulator cannot be energized by remote control signals. Power is still present on the input power terminal TB3 (12).

2.Disengage disconnect switch or external circuit breaker to remove input power.
