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 converter 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 230 V auxiliary voltage
transformer are suitable for the supply voltage in use (See Chapter 5.4).
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 300 m.
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.
5
If cable insulation checks are needed, see Chapter 8.1.1.
