5. CONFIGURATION

Settings may only be changed by a qualified electrical engineer.
•
Read the instructions thoroughly before implementing changes.
•
During setting of the charger, the AC input must be removed.
•

5.1 Standard settings: ready for use

On delivery, the MultiPlus is set to standard factory values. In general, these settings are suitable for single-unit operation.
Warning: Possibly, the standard battery charging voltage is not suitable for your batteries! Refer to the manufacturer's
documentation, or to your battery supplier!

5.2 Explanation of settings

Settings that are not self-explanatory are described briefly below. For further information, please refer to the help files in the software
configuration programs (see Section 5.3).
Inverter frequency
Output frequency if no AC is present at the input.
Adjustability: 50Hz; 60Hz
Input frequency range
Input frequency range accepted by the MultiPlus. The MultiPlus synchronises within this range with the AC input frequency. The output
frequency is then equal to the input frequency.
Adjustability: 45 – 65 Hz; 45 – 55 Hz; 55 – 65 Hz
Input voltage range
Voltage range accepted by the MultiPlus. The MultiPlus synchronises within this range with the AC input voltage. The output voltage is
then equal to the input voltage.
Adjustability: Lower limit: 180 - 230V
Upper limit: 230 - 270V
Note: the standard lower limit setting of 180V is intended for stand alone operation only. In case of high power parallel or 3
phase systems, the lower input voltage limit stting must be increased to 210V or more.
Inverter voltage
Output voltage of the MultiPlus in battery operation.
Adjustability: 210 – 245V
