b. Mounting to electrical box:
Bring wires installed in step 4 through center hole
of mounting plate.
Align appropriate holes in mounting plate with
mounting screw holes in electrical box. Fasten
plate to single gang box using the two #6-32 x 5/
8" (16 mm) screws supplied with the signal, or
fasten to octagon or square box using screws
supplied with the box.
c. Weatherproof installation:
Fasten the Cat. No. 349 Weatherproof Box to the
mounting surface by installing the three
#8 x 1 1/4" (32 mm) wood screws and three fiber
washers, supplied with the box, through the
mounting holes in the rear of the box.
Bring wires installed in step 4 through 3/4" (19
mm)-14 NPT conduit and through conduit entrance
hole into box. Secure conduit to box.
Align appropriate holes in mounting plate with
mounting screw holes in bosses of box and fasten
plate to box using the four #8-32 x 7/16" (11 mm)
machine screws supplied with the box.
5. Connect wires from power source or transformer to
the terminals of the plug receptacle on the mounting
plate as shown in Figure 3.
6. Hook signal on mounting plate by engaging hanger
on plate into slot in top of signal housing (Figure 3).
Press signal flush to mounting plate to mate plug in
rear of signal housing with plug receptacle on

2. Fasten the Cat. No. 349-R Weatherproof Box to the
mounting surface by installing the three #8 x 1 1/4"
(32 mm) wood screws and three fiber washers, supplied
with the box, through the mounting holes in the rear
of the box.
3. Bring 250V DC power source wires through 3/4" (19
mm)-14 NPT conduit and through conduit entrance
hole into box. Secure conduit to box.
4. Place resistor bracket assembly P-039964-0424 in box
with resistor facing rear of box as shown in Figure 5.
Connect the 250V power source wires to the terminals
on the assembly (Figure 4).
5. Bring the two wire leads from the resistor bracket
assembly through the center hole in the mounting
plate. Align holes in bracket with mounting screw
holes in lower bosses of box when upper conduit
entrance hole is used (Figure 5). When bottom conduit
entrance hole is used, bracket must be aligned with
screw holes in upper bosses in box.
6. Align appropriate holes in mounting plate with
mounting screw holes in bosses of box, and fasten
