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
