Act Net devices, such as the i-Vu® Smart Valves

•
Cannot be powered by the TV-MPCXP1628- NR’s 24 Vac transformer
CAUTIONS
•
If the power source for the Act Net devices require a connection to earth ground, you must place it in the
same control panel as the TV-MPCXP1628-NR controller, so that it shares a common earth ground reference,
thereby reducing the potential for ground loops.
•
A remote Act Net power source, installed near the Act Net devices, should be floating (no local connection to
earth ground).
The TV-MPCXP1628-NR provides an orange, three-pin removable screw terminal connector for the Act Net port.
The Act Net port's NC (not connected) terminal does not connect to any internal circuitry of the TV-MPCXP1628-
NR. It is strictly for terminating wires in a daisy chain bus configuration.
NOTE Make sure you wire the Act Net port terminals on the controller to the matching terminal on the i-Vu®
Smart Valve. The following illustration is an example of wiring and powering i-Vu® Smart Valves and the TV-
MPCXP1628-NR's Act Net port.
