WARNING
• Batteries produce explosive gases – Ensure no sparks or flames are present.
• Wear eye protection.
• Vehicles must be in ‘ EUTRAL’ or ‘PARK’, park brakes ‘O ’.
• Follow all vehicle manufacturers’ instructions.
• Beware of moving parts.
• Voltage Sensitive Relays (VSR) are designed for negative ground alternator systems with batteries of the
same nominal voltage.
• Batteries of differing voltages cannot be used.
FEATURES
Projecta’s Voltage Sensitive Relays (VSRs) are suitable for a wide variety of 12V DC applications.
VSRs sense the input voltage and automatically connect/disconnect the appliance or circuit at the set voltages.
The cut-out has an 8 sec. delay preventing the relay from disconnecting during a momentary drop in voltage.
Manual override
The VSR’s manual override can be used to jumpstart your vehicle in the event of a flat starting battery.

INSTALLATION
1. Disconnect the negative battery cable (Earth) from the starting battery.
Note: To prevent the loss of the vehicle’s electronic memory, preset radio and security codes it is
recommended that an ‘Electrical System Memory Protector’ (P/ o. IPS700) be used.
2. Mount the VSR in a convenient location. Mount as far away as possible from the exhaust manifold,
turbo or any other high temperature components. Do not mount on the engine.
INSTALLATION – CONNECTION
To make electrical connections, all cables need to be made to the correct length using cable lugs and
heatshrink. Cable lugs should be crimped or soldered to the stripped battery cable and then protected
with the heatshrink.
Follow the diagram below to complete the installation.
