kW
22.1 Supply voltage
3 x 380-480 V - 10 %/+ 10 %, 50/60 Hz - 3 %/+ 3 %, PE.
Recommended fuse sizes
Standard as well as quick-blow or slow-blow fuses may be used.
22.2 Overload protection
The overload protection of the E-motor has the same
characteristic as an ordinary motor protector. As an example, the
E-motor can stand an overload of 110 % of I
nom
for 1 min.

Warning
When the motors are
installed in residential areas,
supplementary measures
may be required as the
motors may cause radio
interference.
Motor sizes 11, 18.5 and 22 kW comply with EN
61000-3-12 provided that the short-circuit power at
the interface point between the user's electrical
installation and the public power supply network is
greater than or equal to the values stated below.
It is the responsibility of the installer or user to
ensure, by consultation with the power supply
network operator, if necessary, that the motor is
connected to a power supply with a short-circuit
power greater than or equal to these values:

Note
15 kW motors do not comply with EN
61000-3-12.
By installing an appropriate harmonic filter between
the motor and the power supply, the harmonic
current content will be reduced. In this way the 15
kW motor will comply with EN 61000-3-12.
Immunity
The motors fulfil the requirements for both the first
and second environment.
