safety Instructions
connecting to Multi-Wire Branch circuits
do not directly connect the hot side of the 120 VAc of the inverter to the two hot legs
of the 120 / 240 VAc electrical breaker panel / load centre where multi-wire (common
neutral) branch circuit wiring method is used for distribution of Ac power. This may
lead to overloading / overheating of the neutral conductor and is a risk of fire.
A split phase transformer (isolated or auto-transformer) of suitable wattage rating
(25% more than the wattage rating of the inverter) with primary of 120 VAc and
secondary of 120 / 240 VAc (Two 120 VAc split phases 180 degrees apart) should be
used. The hot and neutral of the 120 VAc output of the inverter should be fed to the
primary of this transformer and the 2 hot outputs (120 VAc split phases ) and the
neutral from the secondary of this transformer should be connected to the electrical
breaker panel / load centre.
Preventing input over Voltage
It is to be ensured that the input voltage of the inverter does not exceed 16.5 Vdc to
prevent permanent damage to the inverter. Please observe the following precautions:
- Ensure that the maximum charging voltage of the battery charger / alternator / solar
charge controller is below 16.5 Vdc.
- do not use unregulated solar panels to charge a battery. under cold ambient
temperatures, the output of the solar panel may exceed 16.5 Vdc. Always use a
charge controller between the solar panel and the battery.
- do not connect a 12 Vdc input inverter to a battery system with a voltage higher
than 12 Vdc nominal.
Preventing Reverse Polarity on the input Side
when making battery connection on the input side, make sure that the polarity of bat-
tery connection is correct (connect the Positive of the battery to the Positive terminal of
the inverter and the negative of the battery to the negative terminal of the inverter). If
the input is connected in reverse polarity, fuse(s) on the dc input side will blow and may
also cause permanent damage to the inverter.
