Operation
The Shut Down Timer (SDT) is intended to shut down electrical equipment at a preset
delay time after the automobile engine is turned OFF. This protects the battery and the
equipment from damage due to over discharge or low input voltage.
Installation
• Mount the SDT in a cool, dry place. An optional splashproof version is also available.
The SDT is connected between the +12 volt of the vehicle electrical system and the loads to
be controlled. The loads may be radios and computers or other electrical loads (lights and
flashers).
• The SDT terminal marked +BAT must be connected to the system +12 volts through a
suitable fuse, using appropriately sized wire. Better protection is provided if multiple loads
are fused individually between the SDT and the load.
Note - On some models, each output connection can be protected by a fuse rated at 15 amps
max.
• Loads are connected to either or both of the +OUT terminals.
• On models with the high current terminal block, strip back the wire .35" prior to insertion.
Use #10 spade lugs on the screw terminal models.
• Connect the GND terminal to a good chassis ground. The SDT is powered from the
+BAT input and this ground.
• Activation of the SDT timing period may be automatic by sensing the battery voltage drop
when the engine is turned OFF or by the optional IGN connection to the ignition switch.
• For the ignition switch activation option, connect the IGN terminal of the SDT to the igni-
tion switch terminal that goes to zero volts when the engine is turned OFF.
• The GND and IGN connections carry very little current (< .1 amp). Wire gauge is deter-
mined by mechanical suitability. Strip back wires .25" prior to installation.
Note - When using the ignition switch option, the SDT period will not start if the engine
dies.
