Connection To The Voltage Source - VOLTCRAFT MSW 300 Operating Instructions Manual

6. CONNECTION TO THE VOLTagE SOURCE

Before connecting the inverter and taking it into operation, read the entire operating
instructions; specifically observe the chapter "Safety notes".
Connection cable with cable lugs/alligator clamps
• Switch off the inverter (switch position "O").
• If the inverter is to be connected in a vehicle, switch off the vehicle's ignition.
• Check if the input voltage indicated on the inverter matches the voltage source (e.g. a car
battery) used by you.
If this is not the case, the inverter must not be connected to the voltage source.
• Depending on the power taken from the inverter, the direct voltage source (e.g. a car bat-
tery) must be able to supply the corresponding current strength.
Observe that the actually required current is higher due to conversion loss in the inverter
(approx. by 20%).
Example:
A consumer with a power consumption of 120 W is connected to the inverter.
For a inverter with an input voltage of 12 v/DC, a current of 10 A results. Due to the conver-
sion loss, the input current is 10 A + 20% = 12 A.
For a inverter with an input voltage of 24 v/DC, a current of 5 A results. Due to the conver-
sion loss, the input current is 5 A + 20% = 6 A.
• First connect the black connection terminal of the inverter to the minus pole (-) of the
voltage source via the enclosed connection cable. If the rechargeable battery is installed in
the vehicle, the alligator clamp is attached to a motor part instead of the minus pole of the
rechargeable battery.
Then connect the red connection terminal of the inverter to the plus pole (+) of the voltage
source via the enclosed connection cable.
