Q. How do I check or change the fuses?
A. The inverter contains internal fuses; these should only be checked or replaced by
a suitably qualified person.
THE DC SUPPLY MUST BE DISCONNECTED BEFORE ANY REPAIR, THEN TURN THE
ON/OFF SWITCH OF THE INVERTER "ON" TO DISCHARGE THE CAPACITORS.
Q. Why does the fan only operate sometimes?
A. These inverters feature a temperature controlled automatic cooling fan, that only
operates when needed. This allows the inverter to run very quiet when under low load
conditions.
Q. Why do some power tools not work properly?
A. Some power tools use PWM variable speed controllers to vary the tool's speed as the
trigger is squeezed. These power tools switch the power on and off very quickly in a
similar way to how the inverter works. Because of this, some may not function
properly with the inverters MSW output. On the other hand, a speed control can
reduce the start-up current of the motor and allow an appliance to be used with an
inverter where otherwise it would cause it to overload.
Q. Can I run a laptop computer?
A. Most laptop/notebook computer AC power adapters work perfectly fine with the
inverter's modified sine wave output. Some however are more sensitive and may
not function properly. If your power adaptor does not function or causes a humming
noise or interference on the screen it is probably not suitable. Try using a universal
AC adapter with your laptop or try using a TSW inverter.
Q. Can I connect lights with dimmers to the inverter?
A. Some old "TRIAC" type AC light dimmers may not work with a MSW inverter - try a
TSW inverter instead. Most new "MOSFET" type AC light dimmers and motor speed
controllers will work with MSW inverters but check with the manufacturer first. The
Clipsal 32V and Kambrook KD2 power board with dimming outlet were tested with a
Meanwell MSW inverter and they worked fine, hence some AC dimmers can work
with MSW inverters! Note, dimmers and speed controllers with "soft-start" capability
are an excellent way to reduce and limit the start-up current impact on the inverter.
