Motor
The 12v DC electric motor receives power from the DCB to activate the pump.

A SAFETY HAZARD.
DC Powered Units
DC PROTECTOR IVs are powered using the provided solar panel. Supply requirements are 12v DC nominal.
Voltages in excess of 14.5v DC can cause permanent damage to electronic controls. The solar panel charge
controller ensures the batteries are not over charged.
AC Powered Units
Units operating with AC power are equipped with an AC/DC converter to produce DC power to maintain the
battery condition. The power supply requires 95-135v AC or 200-250v AC, 50-60Hz, single phase AC. Power is
to be supplied by the customer. The trickle charge to the battery is typically 13.8v DC.
Solar Panel
Every new PROTECTOR IV shipped with a solar package contains the following basic components:
• Solar panel with Lexan Vandal Guard and the voltage regulator mounted inside the clean hands section.
• Solar panel cable wired to the panel at the factory.
• Solar panel pole kit (if ordered).
Smart Wheel Sensor
PROTECTOR IV assemblies are equipped with a bi-directional smart wheel sensor as standard. This can be

control circuit. The magnet itself is encased within the body of the sensor block, surrounded by a protective
plastic casing.
There is a short length of cable attached to the sensor with a pigtail connection. This mates to a length of cable
feeding directly to the DCB. The wheel sensor is delivered with a bracket designed for mounting to the rail, and
shims to adjust the sensor height.
Tank
The tank is designed with two separate sections; the materials section that contains the grease and the
components section. The tank body should be secured to a base to ensure its stability and for drainage.
Typically, tanks are mounted to wooden ties or sleepers or a concrete pad.
Distribution Hoses
The distribution hoses are used to distribute the grease from the tank to the rails. The hoses can be installed
once the tank and the distribution bars are in place on the rails.
