To direct surface mount the base:
1. Remove the two knockouts for mounting screws from the
signal base bottom. See Figure 1 for the location of the
knockouts.
2. Place the mounting gasket provided in the hardware kit on
the mounting surface, and mark the center of the three
holes in the gasket onto the mounting surface. Remove
the gasket, and then drill a 3/8 in. (9.5 mm) hole at each of
the marked positions. See Figure 2.
3. Install the two rubber expansion plugs provided in the
hardware kit into the two outer holes in the mounting
surface as shown in Figure 2.
4. Route the field wiring from the required power source for
the signal (refer to its label for the voltage rating) through
the center holes in the mounting surface, mounting gasket,
and signal base.
5. Align the holes in the mounting gasket with the holes in
the signal base. Insert the two screws with lock washers
provided in the hardware kit through the mounting holes
inside the base and align the screws with the rubber
expansion plugs as shown in Figure 2.
6. Press the base firmly against the mounting surface and
tighten the screws.
7. Proceed to “Wiring” below for wiring connections.
Figure 2: Direct surface mounting
Note: For direct surface mounting, the 51XBRF series signals
may be installed in any position.
WARNING: To prevent leakage and a potential shock hazard,
when mounting outdoors the signal must be installed with the
lens or dome facing directly up.
To mount on ½ in. NPT conduit:
1. Route the field wiring from the required power source for
the signal (refer to its label for the voltage rating) through a
½ in. NPT conduit (not supplied) and through the center
hole in the signal base.
2. Install the base on the conduit.
3. Proceed to “Wiring” below for wiring connections.
To mount on a 4 in. (102 mm) octagon box (indoor
installation only):
1. Remove the two knockouts for mounting screws from the
signal base bottom. See Figure 1 for the location of the
knockouts.
2. Route the field wiring from the required power source for
the signal (refer to its label for the voltage rating) through
the center hole in the base.
3. Fasten the base to the octagon box (not supplied) by
installing the screws supplied with the box through the
holes in the base.
4. Proceed to “Wiring” below for wiring connections.
Wiring
To wire 24 VDC models:
1. Using wire nuts (not supplied), connect the signal's red
wire to the positive (+) power source lead and connect the
black wire lead to the negative (−) power source wire.
2. Neatly place the connected wires inside the base, and
then carefully position the lens/lamp assembly onto the
base.
3. Turn on the power, and then verify that the signal operates
properly.
To wire 120 VAC models:
1. Using wire nuts (not supplied), connect the signal's black
wire to hot power source lead and connect the white wire
lead to the neutral power source wire.
2. Connect the green wire to the earth ground connection.
3. Neatly place the connected wires inside the base, and
then carefully position the lens/lamp assembly onto the
base.
4. Turn on the power, and then verify that the signal operates
properly.
