6.1.3 Installation instructions
1
Before starting the installation, check that none of the components of the
frequency converter is live.
2
The NXL frequency converter types MF2 and MF3 shall be installed inside
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 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 30 m (MF2-MF3), 50 m
(MF4) and 300 m (MF5 – MF6).
The motor cables should cross other cables at an angle of 90 degrees.
4
If cable insulation checks are needed, see Chapter 6.1.5.
5
Connect the cables:
Strip the motor and mains cables as advised in Table 6-4 and Figure
6-5.
Connect the mains, motor and control cables into their respective
terminals (see e.g.).
For Information on cable installation according to UL regulations see
Chapter 6.1.4.
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 motor 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
between the frame and the protection plate.
