D. Electrical Connections
The model LP3M comes assembled from the factory. Models are supplied with a two position
terminal block for making electrical connections.
To avoid electrical shock hazards, do not connect to supply circuit when power is applied.
1. Remove the lens from the housing by turning counter-clockwise.
2. Remove the printed circuit board assembly by depressing the two snap tabs inside the
housing and lifting the board assembly upwards.
3. Route supply wires (14 AWG to 18 AWG) into the housing through the hole in the housing.
4. Strip a maximum of 0.25" (6.4 mm) of wire insulation from the ends of the power leads.
Connect wires to terminal block by inserting the stripped ends of the wire into the connector
as far as they can travel and tightening the clamping screw.
Be sure to observe polarity on the 12-48 VDC printed circuit board assembly. The terminals are
designated by a "+" and "-" on the terminal block for the positive and negative
The maximum tightening torque is 5 in-lb (.6 Nm) for field wiring connections on the
terminal block. Make sure power supply lead insulation is flush with connector. If stranded
wire is used, be sure that there are no loose strands outside the connector that could touch
the adjacent lead to cause a short circuit.
5. To reassemble, snap printed circuit board assembly into housing making sure that the board
rests on its' mounting platforms. Take care not to pinch supply wires when inserting board.
6. Thread lens onto housing by turning clockwise until lens is fully seated.
7. Install supplied locking screw on lens to secure.
8. Energize the supply circuit and test strobe light for proper operation.
II. STROBE TUBE REPLACEMENT
After extended operation, occasionally check for flash tube degradation. Should the flash tube
misfire, have a noticeable decrease in light output, glow continuously or darken-replacement is
necessary.
High voltages are present inside the light assembly. Wait at least 5 minutes after
A. Disconnect power from the supply circuit and wait five minutes before opening unit to allow
all capacitors to discharge.
