MODEL NO’s: PI1100, PI1500, PI2000
1. SAFETY
▲ DANGER! - Beware, lead-acid batteries generate explosive gases during normal battery operation.
9 Wash with soap and water immediately if battery acid contacts skin or clothing. If acid enters eye, flush immediately with cool,clean
running water for at least 15 minutes and seek immediate medical attention.
8 DO NOT smoke or allow a spark or flame in the vicinity of the battery or engine.
9 If the battery terminals are corroded or dirty, clean them before attaching the leads.
WARNING! To prevent the risk of sparking, short circuit and possible explosion DO NOT drop metal tools in the battery area, or allow
them to touch the battery terminals.
9 Before attaching to battery, remove personal metallic items such as rings, bracelets, necklaces and watches. A lead acid battery can
produce a short-circuit current which is high enough to weld such items to the vehicle and cause severe burns.
9 Keep children and unauthorised persons away from the working area.
WARNING! DO NOT use on any vehicles other than those with 12Volt DC systems.
WARNING! These inverters produce voltages similar to mains AC power; beware of electric shock.
8 DO NOT connect to any AC power source.
8 DO NOT dismantle. The inverter must be checked by qualified service personnel only.
8 DO NOT get inverter wet or use in damp or wet locations or areas where there is condensation.
8 DO NOT use the inverter for any purpose other than for which it is designed.
8 DO NOT pull the cables or clips from the battery terminals.
8 DO NOT in a flammable atmosphere.
8 DO NOT operate the inverter if damaged.
8 DO NOT connect to a positive earthed system. Ensure you have the polarity correct before connecting, red cable to positive (+) battery
terminal and black cable to negative (-) battery terminal.
9 Before connecting ensure nothing is plugged into the inverter, and the inverter is switched OFF.
WARNING! Inverters become hot during use.
9 When not in use store inverter in a safe, dry, childproof location.

4. OPERATION
4.1. ELECTRICAL CONNECTIONS
4.1.1. Ensure that the main switch (g.1.6) is in the off position before making any connections.
4.1.2. Remove the plastic cover, nut and spring washer from the negative (-) terminal of the inverter (g.1.7) and place the ring connector on
the black cable over the terminal post.
4.1.3. Secure the cable with the spring washer and nut and replace the plastic cover.
4.1.4. Repeat 4.1.2. and 4.1.3. to connect the red (+) cable and fuse to the positive (+) terminal (g.1.8)
4.1.5. If required, connect an earth cable to the earth terminal (g.1.10). For further information, consult an automotive electrician.
4.2. USAGE
4.2.1. Once connected to the battery supply, switch the main switch (g.1.6) on.
4.2.2. Switch the inverter circuit on by means of the on/off button (g.1.2).
4.2.3. When switched on, the digital display (g.2) will light.
4.2.4. The main display can show input battery voltage or output amperage. Pressing the display selector button changes the display from
one to the other.
4.2.5. Before connecting an appliance to the 230V output (g.1.5) ensure that the appliance is switched off.
4.2.6. When connected, switch the appliance on.
4.2.7. Small appliances may be connected to the USB ports (g.1.4).
4.2.8. If the fault alarm sounds, the fault will show on the digital display (g.2).
4.2.9. Inductive loads, such as TV’s and stereos, require more current to operate than do resistive loads of the same wattage rating. Induction
motors, as well as some televisions, may require 2 to 6 times their wattage rating to start up. The most demanding in this category are
those that start under load, such as compressors and pumps. Testing is the only denitive way to determine whether a specic load
can be started and how long it can run. The unit will simply shut down if it is overloaded. To restart the unit after a shutdown owing to
overloading, remove the overload.
4.3. PERMANENT INSTALLATION
4.3.1. If mounting the inverter permanently, mount in a cool, dry location close to the vehicle battery. DO NOT mount the inverter in the engine
compartment.
4.3.2. Mount the inverter horizontally, with room for air circulation around the unit.
4.3.3. Offer the unit up and mark the positions for the xings; ensure that the xings do not disturb any wiring, piping or reservoirs.
4.3.4. Drill on the markings and secure the unit.
4.3.5. Connect wiring as in section 4.1.
4.3.6. A remote control is supplied if the unit is to be operated in an inaccessible location. Plug one end of the USB cable into the remote
control socket (g.1.9) and the other into the rear of the remote control switch.
4.3.7. Switch the main switch on and connect the 230V outlet to the required extension socket.
4.3.8. The remote switch will now switch the inverter on and off as required (an LED illuminates in the switch when switched on).
