Mastervolt MASS COMBI 12/2500-100

OPERATION

4.3.2 Output overload or short circuit
In case of overload or short circuit in the inverter mode,
the 100% LED of the Power bar (see figure 15) is
illuminated red and the output voltage of the Mass Combi
is limited. The Mass Combi shuts down if this overload or
failure lasts longer than 5 seconds.
The Mass Combi will automatically restart after shutdown.
After 5 failed start attempts the Mass Combi shuts down
permanently, the 100% LED is lit and the Inverter LED
(see figure 15) will flash You can restart the Mass Combi
only by switching the unit manually off and on with the
main switch on the Mass Combi after the overload is
removed or failure is solved.
4.3.3 Overheating
In the event of overheating the Mass Combi shuts down
(see chapter 9.1 for illumination of indicator lights). The
Mass Combi is automatically powered up again when the
temperature drops below the factory default threshold.
Overheating is most likely caused by:
• heavy or non-resistive loads operating for a longer time
• high ambient temperature
• disrupted air flow (dust or too less space)
4.3.4 Under and over voltage
The AC-input of the Mass Combi is, within limits, protected
against over and under voltage. See specifications in
section 10.2. The Mass Combi will switch to inverter mode
if the AC-input voltage is out of operating range and will
switch back if the AC-input voltage is present again.
The DC-input of the Mass Combi is also, within limits,
protected against over and under voltage. See
specifications in section 10.1. The Mass Combi switches
off if the DC-input voltage is out of range.
4.4 MAINTENANCE
No specific maintenance is required. If necessary, use a
soft clean cloth to clean the Mass Combi. Never use any
liquids, acids and/or scourers.
4.5 PROBLEM SOLVING
Refer to chapter 9 if a problem occurs.
