D. Electrical Connections
1. Typical Connection Method
The USIX UniStat comes partially assembled from the factory. To complete the
connections, perform the following steps. See Figure 1 for additional information.
a. Remove the lens guard by twisting counter-clockwise (as viewed from the top).
b. The electrical connections can be made at the terminal block of the unit using 18
AWG or 20 AWG solid copper or stranded wire.
To avoid electrical shock hazards, do not connect wires when power is applied.
c. 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.
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. For
all non-conductive fixtures, maintain the integrity of the ground of the conduit by wiring
from one side of the fixture conduit to the other.
d. Connect the lens guard by twisting it in the clockwise direction. Do not over-
tighten the guard or you may crack it.
e. Test the UniStat USIX to ensure that it operates as intended.
2. Alternate Connection Method (complete disassembly)
a. Remove the lens guard by twisting it counter-clockwise (as viewed from the top).
Remove the glass dome by twisting it counter-clockwise. Remove the lens by twisting it
counter-clockwise until it unlocks. Lift the lens upward and off the base unit and retain the
O-ring.
b. Remove the two Phillips-head #6 screws and disassemble the sleeve from the
base. The printed circuit board with LED array will remain attached to the sleeve allowing
access to the terminal block. Use caution not to over-flex or damage the LED ribbon cable.
Retain the O-ring for the sleeve.
c. The electrical connections can now be made to the terminal block of the unit.
