6.1.3 Energy saving mode
See section 3.2.2 for more information.
If you want… DIP switch A
SW4 SW5
High Power (Energy saving disabled). OFF OFF
Idle 40VA. When it detects a load that is >40VA, it switches on the output power automatically. ON OFF
Idle 150VA. When it detects a load that is >150VA, it switches on the output power automatically OFF ON
Economy 208V. The output voltage will drop to 208V as long as the connected load stays below 250VA. ON ON
Note: The power saving modes “Idle 40VA” or “Idle 150VA” can only be selected with a Mass Combi 12/2500-100, Mass
Combi 24/2500-60 or the Mass Combi 48/2500-35 operating as stand-alone unit. These modes are not available with a
Mass Combi 48/5000-70 or two Mass Combi’s in parallel operation.
6.1.4 Battery type
The factory setting for the battery type is optimal for most installations. In some applications however, it is desirable to change
this setting. Adjust the Mass Combi to the applied batteries by adjusting DIP switches SW6 and SW7.
Wrong adjustment can cause damage to your batteries which is not covered by the warranty.
The setting for traction battery should never be used with a battery bank that consists of 2V GEL cells!
If you want… DIP switch A
SW6 SW7
Standard battery (factory setting) OFF OFF
Gel / AGM / spiral battery. During the float stage of the charging cycle the output voltage will be higher (+
0.55V @ 12V / + 1.1V @ 24V / + 2.2V @ 48V)
ON OFF
Traction battery. Charging voltage will be increased during the bulk stage (+ 0.7V) and the absorption
stage (+ 0.4V)
OFF ON
Forced float. When activated, the three stage charging program is changed to a single stage program.
Fixed output voltage: 13.8V (@12V), 27.6V (@24V) or 55.2V (@48V)
ON ON
6.1.5 Ground relay
The ground relay function allows you to connect the Neutral conductor (N) of the inverter output circuit to the Safety Ground
(PE / GND) automatically when the Mass Combi is working as an inverter. With most electrical installations in the USA this
ground relay must be set to ON. Refer to local regulations on this issue.
If you want… DIP switch A
SW8
no internal connection between the Neutral (N) and the Safety Ground (PE / GND) when the Mass Combi
is working as an inverter
OFF
the Neutral wire (N) of the inverter output circuit connected to the Safety Ground (PE / GND) when the
Mass Combi is working as an inverter and disconnected when incoming AC-power is applied (charger /
transfer mode).
ON
