U> (10Min) Der. Enables power derating mode due to high average grid voltage readings
Slow Ramp
Enables gradual ramping up of power after the grid connection.
OF Derating Selects the power derating mode in the event of grid over-frequency.
Time period after OF derating in which the inverter checks that the fre-
quency is back within the operating ranges (parameters Fconn< and
OF Der. Rest. T
Fconn>) required by the grid standard before ramping up the output from
the derating condition
Enables Amorphous Mode in the event that the negative input pole is
Amorph. Enable
grounded by installing the Negative Grounding Kit (not available)
Unlocks the grid standard selection (resets the 24 hours available for chan-
Reset Country S.
ging the grid standard)
Allows manual setting of the Ethernet board IP address This function may
Upgrade IP Addr be useful where static Ethernet board addresses are used (DHCP disa-
bled)
We advise you to memorize the new password with great care.
If the Password is lost you will not have access to the inverter, since there is no Reset function
for security reasons
