Residual Current Device (Rcd) - Projecta IM120 User Manual

SUITABLE POWER SUPPLY
In order to operate the inverter and supply power to an appliance, a suitable 12VDC power
supply is required. This can be a vehicle or caravan battery, portable power pack or an
independent 12V lead acid battery. For most applications, a deep cycle battery is recommended
for optimum performance. The size of the battery used will determine how long the inverter
will supply power to an appliance and how well the inverter will perform. Most batteries are
marked with their size in Amp hours (Ah) or Cold Cranking Amps (CCA).
Because 12V inverters are capable of drawing high currents the inverter should only be
connected to a suitable sized battery. Connection to an undersized battery could damage the
battery and will result in the inverter shutting down within a short period due to low battery
voltage. The amount of power drawn from the battery is proportional to the inverter load.

RESIDUAL CURRENT DEVICE (RCD)

For added safety it is recommended that a Type "A" Residual Current Device (RCD) be used for
any appliance that is being operated by the inverter. These are sometimes called "Safety Switches"
and are designed to be connected between and appliance and power source.
1. Connect the RCD to the inverter AC outlet socket
2. Connect the appliance to the other end of the RCD
3. Turn the power supply "ON"
4. Follow the manufacturer's instructions to turn the RCD "ON" and "TEST" that it is
functioning correctly.
5. Turn the appliance on.
NOTE: Some RCDs do not work properly with the inverter's "Modified Wave" output. Check with
the RCD manufacturer and always follow the manufacturer's "TEST" procedure to check that the
RCD is functioning correctly.
USING THE INVERTER IN VEHICLES
The Inverter Power-Can' is best used whilst the engine is running. This will minimise the risk of
flattening the car's starter battery even though the Inverter will shut down if the battery voltage
falls below 10V (Note: 10V is not sufficient voltage to start a car). To use the Inverter for an
extended period of time without the engine running, it is recommended to run it from a second
battery or a dual battery system to avoid flattening the car's starting battery.
