There are two removable terminal blocks on the rear of
the units . The terminal blocks, as viewed from the rear,
are labeled TB3 (left side, green), and TB2 (right side,
black) .
TB3 is used to connect the EPC-A to the unit . Wire
the terminal block from left to right, with the blue, black,
and red wires going to the EPC-A, wire length not to
when the light level is twice the preset footcandles .
