Federal Signal USIX-024 Manual De Instalación Y Mantenimiento página 6

To avoid electrical shock hazards, do not connect wires when power is applied.
d. Feed the power and control wires through separate openings in the junction box
of the base with appropriate conduit or comparable material suitable for the location in which
it is being installed. Then connect the wires to the connector as indicated in Figure 3, Table 2.
Reference Table 1 for color and function selection on all models.
e. Before reassembling, make sure the O-ring is in place between the base and
sleeve. To reassemble the base unit, first attach the sleeve onto the base by sliding the printed
circuit board into the channels on the base. Fasten the sleeves onto the base by reinstalling
the screws removed in step 2.b. above. Make sure the gasket is placed on the base before
the sleeve is put back on.
f. Reassemble the lens onto the base unit, and place the O-ring between the lens
and base. Apply a clockwise twisting motion to the lens until it locks into place.
g. Attach the base to the junction box with the four screws and secure tightly. Install
glass dome by twisting clockwise and secure tightly.
To ensure trouble-free operation of the fixture, ensure that the conduit has been secured
to 200 in-lb. (22.6 Nm). Do not over-tighten as it may cause the enclosure to fracture.
When tightening the dome, be certain that the silicone rubber gasket is completely
compressed. Do so by turning the dome 1/8 to 1/4 rotation past "hand-tight." For all
non-conductive fixtures, maintain the integrity of ground of the conduit by wiring from
one side of the fixture conduit to the other.
h. Connect the lens guard by twisting it in the clockwise direction. Do not over-
tighten the guard or you may crack it.
i. Test the UniStat USIX to ensure that it operates as intended.
