INSTALLATION INSTRUCTIONS
1
Before starting the installation, check that none of the components of the
frequency converter is live.
2
Make sure that the space where the converter is installed, and the con-
verter itself, is clean and free from particles, dust or humidity that could
harm the converter when it is powered on.
3
Make sure the connection of the AC choke and the optional 230V auxiliary
voltage transformer are suitable for the supply voltage in use (See
chapters 5.4 and 0).
4
Place the motor cables sufficiently far from other cables:
Avoid placing the motor cables in long parallel lines with other
cables
If the motor cables run in parallel with other cables, note the
minimum distances between the motor cables and other cables
given in table below.
The given distances also apply between the motor cables and
signal cables of other systems.
The maximum length of the motor cables is 300m.
If output du/dt filters (+ODU or +ODC options) are used the cable
length is limited according to the table below:
The motor cables should cross other cables at an angle of 90
degrees.

If cable insulation checks are needed, see Chapter 8.1.1.
