Check from the identification label whether the
battery voltage is the same as the DC-input
voltage of the Mass Combi (e.g. 12V battery set
for a 12V battery voltage). Also be sure that the
AC output voltage and output power of the
Mass Combi satisfies loading requirements.

This Quick installation guide provides a brief overview of a basic stand-alone installation of the
Mass Combi. However; please review the entire user’s manual for parallel connection, additional
features and connections and to ensure best performance and years of trouble-free service.

Switch on the Mass Combi.
The LED-indicators will blink
several times

After a few seconds the Mass
Combi starts operating.

12

If not, immediately switch off the DC power supply
and AC power supply. Investigate the cause of the
malfunctioning. See Trouble shooting chapter of the
user’s manual.

Check all wiring.

11

If the wiring is OK:

• Tighten the cable glands;

• Close the connection

compartment;

• Place the DC fuse (when
placing this fuse, a spark can
occur!);

• Switch on the DC source;

• Switch on the AC source.

Recommended DIP-switch settings:

Dip Switch Bank A:

• Single Inverter System: SW1 - OFF, SW2 – OFF.

• Output frequency 60Hz: SW3 – OFF.

• High power mode (energy saving modes disabled): SW4 – OFF, SW-5 – OFF. The Econ omy mode (SW4 – ON,

SW-5 – ON) will save some power but allows clocks and such to run.

• Battery type. Standard Lead acid: SW6 – OFF, SW7 – OFF; Gel or AGM: SW6 – ON, SW7 – OFF.

• Ground relay: SW8- ON. During inverter operation of the Mass Combi, the Neutral wire (N) of the inverter output

will be internally connected to the Ground (PE / GND)

Dip Switch Bank B:

• Power Sharing function, set to maximum power is SW1- OFF, SW2- OFF, SW3 ON. If the Remote APC or
Masterlink MICC is used, you should adjust the Mass Combi to this setting. Then the maximum input power can
be adjusted by means of these remote control panels.

• If Power support is used (boosting power with inverter on Short break output), SW4- ON. If this is used, SW5
must be OFF.

• If Generator and Main power boosting is selected, SW-5- ON. Please note this mode is not recognized by ABYC
as two power sources are mixed. If this mode is still going to be used, SW4- must be OFF.

• Power Quality. Normal setting is SW6- OFF. This allows unit to operate on power from 45-65 Hz. SW6- ON
opens this frequency window to 35- 65 Hz for poorly synchronized generators.

• For operation with remote panels, with the main switch on the Mass Combi to ON.

• SW7- OFF: the remote On-Off switch turns off or on both the charger and inverter remotely.

• SW7- ON: the remote On-Off switch only turns off or on the inverter section only. Battery charger always

operates when external AC power is available.

• SW8- OFF. Equalize should only be used with lead acid batteries at the end of their life cycle and only when
careful monitoring of battery conditions can be observed. See also chapter 6 of the user’s manual.
