Labeling

The Annunciator Module comes with a blank label on the front on which you can write a de-

scription to identify each light—such as the corresponding alarm or output. We include addi-

tional blank labels for your convenience.

POWER SUPPLY AND GROUNDING

The Annunciator Module operates on 10-15VDC. Typically the module is powered from the

AUX PWR terminals on the SCADA 3000 main unit. This is preferred because the AUX PWR

from the main unit is battery-backed in the event of a power failure, when a battery is connected

to the main unit. Alternately, you may connect the module to any 10-15VDC power source.

The module requires 1.5 Watts of power. See Figure 3.

It is extremely important that the EG pin be connected to a good earth ground. This will

prevent communication errors due to differences in ground potential between modules in

addition to possible damage due to voltage transients and surges.
