Installation
Install in accordance with the latest edition of the National Elec-
trical Code and local regulations.
1. (Figure 2) Release the latch on the clamp ring and remove
the ring holding the protective dome to the signal base. Lift
the dome straight up off of the signal base. Loosen the three
screws in the keyhole slots located in the base of the lens.
Turn the lens clockwise and lift it off of the strobe tube support
plate. Remove the three screws holding the strobe tube
support plate to the signal base; grasp the socket on the strobe
tube support plate. Do not touch the glass tube. Carefully
lift the support plate off of the signal base.
2. Mount the 94DDV2(*)-G1 to 3/4" (19 mm) NPT conduit (not
supplied).
WARNING
To reduce the risks of igniting hazardous
atmospheres and of electrical shock, ensure that
power is disconnected before installing the signal.
CAUTIONS
To prevent damage to the strobe tube, lift the lens
straight up and off of the signal.
To prevent damage to the strobe tube, handle the
tube only by the base.
Figure 1. Supervised Wiring Diagram
WARNING
To prevent leakage and a potential electrical shock
hazard, when installing outdoors, the signal must
be mounted with the lens facing directly up.
a. Route the field wiring from the power source through
the conduit and through the conduit entrance hole in the
signal base (Figure 2).
b. Install the signal base on the conduit (Figure 2).
3. For non-supervised circuits, connect field wiring to signal
wiring using wire nuts (not supplied). Connect the signal's
two red positive (+) wire leads to the positive power source
wire and connect the signal's two white (-) wire leads to the
negative power source wire.
4. For supervised circuits, connect field wiring to signal wiring
using wire nuts (not supplied). Connect the signal's two red
positive (+) wire leads and two white (-) wire leads to the
supervised circuit in accordance with Figure 1.
5. Place the connected wires inside the signal base and
reassemble the signal.
6. Turn on the power and verify that the signal operates properly.
