- Proper installation is the responsibility of the manufacturer of the system / machine.
- Observe the data on the rating plate (chapter 3.1) and the information in the wiring
diagrams (Fig. 6 to Fig. 9).
- Compare the data of the forced ventilation unit with the connection data. Prevent
overloading of the unit.
- Connecting leads must be suitable for the type of application and for the anticipated
currents and voltages (Project planning guide).
- As a result of the converter feed, high-frequency current and voltage harmonics in the
motor supply leads can cause electromagnetic interference to be emitted.
Use shielded power and signal lines.
Use EMC cable screw connections for the power terminal in the terminal box. The cable
screw connections are screwed into the tapped holes of the terminal box.
Observe the EMC instructions of the converter manufacturer!
- The ends of the leads must not be stripped further than necessary, i.e. the insulation
must extend to the cable lug, terminal or wire-end sleeve.
- Match the cable lugs or wire-end sleeves to the dimensions of the terminal board
connections and to the cross-section of the power cable, lay parallel connecting leads if
necessary.
- Connect the PE conductor.
- The inside of the terminal box or the connector must be kept clean and free from cable
residues and moisture.
- Tighten all screw connections of the electrical connections (terminal board connections,
except terminal strips) to the specified tightening torque.
- Maintain minimum air gaps of 5.5 mm when attaching the inner connecting cables.
- Avoid protruding wire ends.
- Any cable entries which are not in use must be sealed and the sealing elements must be
screwed in firmly and tightly.
- Check the seals and sealing surfaces of the terminal box and the connector to ensure
that the degree of protection is maintained.
- The connecting leads are to be equipped with the strain relief device and devices which
protect against rotation and transverse forces, and must be prevented from kinking. The
connectors must not be subjected to continuous forces.
- The coding slot on the plug connector must be aligned when inserted into the female
connector in each case. The union nut must be tightened up to the stop by hand!
The protective function with a fitted temperature sensor is inadequate for high thermal loads,
e.g. overload with the motor at a standstill. Additional protective measures are to be provided
for such cases, e.g. a thermal overcurrent relay.
NOTE
Pre-assembled cables from SIEMENS are recommended for the connectors
(not included in scope of delivery). These cables reduce the assembly time
and increase operational safety!
