6.1.2 Installation instructions
1
Before starting the installation, check that none of the components of the frequency
converter is live.
2
The frequency converter shall be installed inside a switchgear, separate cubicle or
electrical room because of the protection class IP20 and the fact that the cable
terminals are not protected.
3
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 runs 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 (level H) of the motor cables is 30 m
(drives with output power greater than 1.5kW) or 10 m (0.75…1.5kW).
The motor cables should cross other cables at an angle of 90
degrees.
4
If cable insulation checks are needed, see Chapter 6.1.4.
5
Connect the cables:
Strip the motor and mains cables as advised in Table 6-2 and
Figure 6-4.
Connect the mains, motor and control cables into their respective

factory or your local distributor.
For Information on cable installation according to UL regulations
see Chapter 6.1.3.
Make sure that the control cable wires do not come in contact with the
electronic components of the unit.
If an external brake resistor (option) is used, connect its cable to the
appropriate terminal.
Check the connection of the earth cable to the motor and the frequency
converter terminals marked with
.
Connect the separate shield of the power cable to the earth plate of
the frequency converter, motor and the supply centre.
Ensure that the control cables or the cables of the unit are not trapped
