Attenuator Installations

Wiring

Each terminal will hold up to 2-16AWG stranded wire. For larger wires or home run situations, a small length of wire and a wire nut are recommended. Attach wire according to label on terminal block as shown to the right (Non-PA Models will not have the "VDC+" and "VDC-" terminals).

*Install the unit with the terminal block on top. This will ensure that the OFF position is in the bottom.
