essary.) When mounting the unit to a wall make sure the mounting screws fully engage a solid
member (for example, a stud) of the support structure. Mount the Universal Input Module in

Power Supply and Grounding
The Universal Input 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.
