Electrical Connections
1. The cable attached to your Traffic Director should have a green connector (part #CPSS-153)
attached to it. Eight colored 18 AWG wires, one bare drain wire, and a large red 12AWG wire
should already be connected from the cable to the connector.
2. Connect a ground wire to the interior empty terminal on the green connector. (See diagram
above) The corresponding terminal plugs into the outlet on the back of the controller and is
marked BAT-.
It is imperative that you supply a ground wire to the terminal marked
"BAT -" on the controller. You must not let the controller's case supply
ground. Use 12 AWG wire for all power and ground connections
3. Supply power for the unit from a fused, +12 VDC source capable of delivering at least
15 amps of current (use a 20 amp fuse). Star recommends the use of an ignition
switched supply to avoid the possibility of draining the vehicle's battery should the unit
be accidentally left on.
If you are utilizing the On/Off Switch bypass option AND you have other devices
connected to the same bypass switch, you MUST connect the bypass power through a
relay to prevent the other devices from powering up when you use the standard On/Off
switch on the TD controller. Please contact our Customer Service Department if you
need further details on this.
4. Connect your power supply to the terminal on the green connector that corresponds to
the outlet on the back of the controller marked BAT+.
5. The lamp brightness will be somewhat diminished if a large voltage drop exists between
the vehicle's battery and the controller. Don't forget to fuse the feed and signal wires
at their source, with appropriate values. It is imperative that you supply a ground wire to
the terminal marked "BAT -" on the controller; you must not let the controller's case
supply ground. Use 16 AWG
(14AWG for 40’+) wire for all power and ground connections.
6. Your Traffic Director should now be ready to operate.
