7. ADDING EXTENSION CORDS
We recommend that the buyer refrain from connecting the DC power source and the inverter's
DC input by means of an extension cord. Connecting an extension cord to the DC input will
create a voltage drop, entailing reduced efficiency and output. Instead, you should use the
extension cord to connect the AC output and the AC appliance. You may use up to 100ft (30m)
of high-quality extension cord. A longer cord may result in reduced power.
8. EARTHING
CONNECTION
WARNING : YOU MUST PROVIDE THE INVERTER WITH AN EARTHING CONNECTION
PRIOR TO USE.
•
The rear panel of the inverter is equipped with a terminal fitted with a wing nut. This terminal
is connected to the case of the inverter and also to the earthing terminal of the AC output
socket. The nature of your installation will determine whether or not you need this terminal.
Always use heavy-duty yellow and green wiring for this connection.
•
In a stationary land-based installation, the earthing terminal should be connected to a metal
earthing stake driven into the ground to a minimum depth of 1.2m. One of the battery
terminals (preferably the negative one) should also be connected to the earthing stake if the
battery system powering the inverter is not equipped with a ground connection.
•
If the inverter is used in a vehicle, where it is wired directly to the battery, the earthing
terminal is simply connected to the chassis. If, however, the inverter has to power equipment
used outside the vehicle, an earthing stake should be used as described above.
•
Connect the earthing terminal to the existing grounding system when the inverter is used on
a boat.
NOTE : The earthing terminal of the AC outlet is connected to the neutral terminal. This is the
same as with a standard household power point where the neutral connection is bonded
to earth and there is no voltage between the two.
9. MEASURING AC VOLTAGES
The output wave of the AC inverter is a MODIFIED SINEWAVE. If you choose to measure the
AC output voltage, you must use an AUTHENTIC RMS VOLT METER. The use of any other
type of voltage measuring device will result in an AC voltage reading that is up to 20 to 30 volts
lower than the rated value. The reading will only be accurate when you are using an authentic
RMS voltmeter.
