C. Electrical Connections
The model AV1 comes assembled from the factory with two color-coded leads for wiring to
a junction box. If desired, the factory leads can be removed and the supply connections can
be directly made to the terminal block located in the lower housing as described below.
To avoid electrical shock hazards, do not connect to supply circuit when power is applied.
If the light has not been disassembled previously for mounting, perform the following steps:
1. Remove the three no. 8 screws and remove the upper housing.
2. Remove the factory field wiring leads from the terminal block.
3. Route supply wires (12 AWG to 16 AWG) into the housing through the conduit entry.
4. Strip a maximum of .25" (6.4 mm) of wire insulation from the ends of the power
leads. Connect phase/negative wire to the (-) terminal and neutral/positive wire to the
(+) terminal. Insert the stripped ends of the wire into the connector as far as they can
travel and tighten the clamping screw (max. tightening torque = 4.5 in-lb {.5 N-m}).
5. Re-assemble the light and test for proper operation.
