Goodrive350 IP55 High-ingress Protection Series VFD
Technical data
-337-
B.2.2.2 Derating due to altitude
When the installation site altitude is lower than 1000 m, the VFD can run at the rated power.
When the installation site altitude exceeds 1000m, derate 1% for every increase of 100m;
when the installation site altitude exceeds 3000m, consult the local INVT dealer or office.
B.2.2.3 Derating due to carrier frequency
The power of Goodrive350 IP55 high-ingress protection series VFDs varies according to
carrier frequencies. The rated power of a VFD is defined based on the carrier frequency set in
factory. If the carrier frequency exceeds the factory setting, the power of the VFD is derated by
10% for each increased 1 kHz.
B.3 Grid specifications
Grid voltage
AC 3PH 380V (-15%)
–440V (+10%)
Short-circuit capacity
According to the definition in IEC 61439-1, the maximum allowable
short-circuit current at the incoming end is 100kA. Therefore, the
VFD is applicable to scenarios where the transmitted current in the
circuit is no larger than 100kA when the VFD runs at the maximum
rated voltage.
Frequency
50/60 Hz±5%, with a maximum change rate of 20%/s

B.4.1 EMC compatibility and motor cable length
The following table describes the maximum motor cable lengths that meet the requirements of
the EU EMC directive (2014/30/EU).
All models (with external EMC filters)
Maximum motor cable length (m)
Environment category II (C3)

You can learn the maximum length of the motor cable through the running parameters of the
VFD. To understand the accurate maximum cable length for using an external EMC filter,
contact the local INVT office.
For description about the environments categories II (C3), see section B.6 "EMC regulations".
