HD2 IP55 High-ingress Protection Series
B.2.2.2 Derating due to altitude
When the installation site altitude is lower than 1000 m, the inverter 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 IMO dealer or office.
B.2.2.3 Derating due to carrier frequency
The power of HD2 IP55 high-ingress protection series inverters varies according to carrier
frequencies. The rated power of an inverter is defined based on the carrier frequency set
in factory. If the carrier frequency exceeds the factory setting, the power of the inverter is derated
by 10% for each increased 1 kHz.

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)
Environment category II (C3)
You can learn the maximum length of the motor cable through the running parameters of the
inverter. To understand the accurate maximum cable length for using an external EMC
filter, contact the local IMO office.
For description about the environments categories II (C3), see section B.6 "EMC regulations".
AC 3PH 380V (-15%)–440V (+10%)
According to the definition in IEC 60439-1, the maximum allowable
short-circuit current at the incoming end is 100kA. Therefore, the
inverter is applicable to scenarios where the transmitted current in
the circuit is no larger than 100kA when the
inverter runs at the maximum rated voltage.
