User and Installation Manual
5 SETTINGS
Adjustment of the settings of the CombiMaster Inverter/Charger can be made in two different ways:
• By means of DIP switches.
• From a laptop connected to the CombiMaster Inverter/Charger via a Mastervolt USB Interface. Some
settings, like the AC IN Limit setting for example, can only be changed in this way.
Invalid settings of the CombiMaster Inverter/Charger can cause serious damage to your
batteries and/or the connected load! Adjustment of settings must be carried out by authorized
personnel only.
