Protect PV.630 Operating Instructions
40 of 72 8000047961 BAL
The inverter is designed for a rated output power (sustained pow-
er) of 630 kW, see the technical data sheet. However, at low sup-
ply air temperatures, the inverter is capable of feeding in a higher
power. When the function is activated, the maximum feed-in ca-
pacity at low supply air temperatures is increased according to a
characteristic curve. If the temperature rises, the maximum feed-in
capacity drops. If the temperature rises above a certain value, the
device can only continue outputting the rated output power. The
relationship between the possible feed-in capacity and the temper-
ature is shown in Figure 13a.
Figure 13 a Extended operating mode
5.6.1 Parameters of the “Extended” operating mode
Temperature value at which the rated output power can be
fed:
If the supply air temperature rises above this value, it is only pos-
sible to continue feeding the rated output power.
Temperature value at which the maximum excess power can
be fed:
If the supply air temperature drops below this value, it is possible
to output the maximum excess power.
Power rating for normal feed-in capacity:
If the supply air temperature rises above the value, it is possible to
feed this power as the maximum. This value corresponds to the
rated output power.
Power rating for increased feed-in capacity:
If the supply air temperature drops below a value, it is possible to
feed this power as the maximum.
6 Monitoring Systems, Messages and Faults
6.1 General
All monitoring systems only generate fault messages when the in-
verter is switched on; when it is switched off, the inverter is always
reported as being free of faults.
