CAUTIONS
○
If the power source for the external Act Net devices require a connection to earth ground, you must place
it in the same control panel as the TV-VVTZC-E2 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-VVTZC-E2 provides an orange, three-pin removable screw terminal connector for the Act Net port.
Be careful to wire the Act Net port terminals on the controller to the matching terminal on the supported device.
They may not be in the same order. See example below.
The TV-VVTZC-E2 supports Act Net communication to the Act Net devices on a bus with a maximum length of 300
feet (91.44 meters). The bus should be wired with copper conductors of an appropriate size (18 AWG or larger) to
compensate for voltage drop and ensure that bus voltage does not drop below 19.2 Vac or 21.6 Vdc.
