2) Connect DC lines to the field-wireable connector, V+ to pin #2 and connect GND to pin #4. See figure 4.
Figure 4: Terminals
3) Wire length from the power supply and zener diode barrier using 2 strand #18 wire AWG (1.02 mm) is up
to 1800 feet (548 meters). Longer distances available depending on wire choice. Maximum wire size of #18
AWG (1.02 mm) and cable size of .236-.315 inches (6-8mm). See specifications below.
4) Reassemble the connector and attached to led illuminator.
5) Switch “ON” the power supply making sure the Illuminator is functioning properly, with all LED’s
illuminated.
6) Refer to the troubleshooting section in this manual if a portion or all of the LEDs do not illuminate
SELECTING WIRE AND BARRIER
Selecting a wire with a lower capacitance (F) will yield longer distances. Use the following equations and
diode parameters below to determine the distance of wire between the LED illuminator and zener diode barrier.
Pick the shortest distance from the two following equations:
IMPORTANT: FARAD and HENRY units must be consistent throughout the equations. Eg: all (uF),
not a mixture of (uF) and (F).
Cable Max Distance 1 = Total Allowable Capacitance (F) / [2 x Wire Capacitance (F)]
Cable Max Distance 2 = Total Allowable Inductance (H) / [2 x Wire Inductance (H)]

ROUTINE MAINTENANCE
Keep window on the front of the light clean using commercial glass cleaners. Never use harsh abrasives,
wire brushes, metal scrapers, or any material that could scratch the window. The window may be cleaned while
the unit is in operation.
