Remove the two Allen screws on the back of the enclosure and slide out the locking side panels.
Insert the module into the hole in the panel and slide it back until the front bezel is flush with
the panel. Re-install the locking side panels and tighten the Allen screws to secure the enclo-
sure to the panel. See Figure 2 below.

Labeling
The Annunciator Module comes with a blank label on the front on which you can write a
description 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 pre-
vent communication errors due to differences in ground potential between modules in addition
to possible damage due to voltage transients and surges.
