Safety rules for working in electrical installations as per
EN 50110-1 (DIN VDE 0105-100):
- Work always with the equipment electrically dead.
- Isolate from electrical supply.
- Secure against switching on again.
- Check electrical deadness.
- Earth and short-circuit.
- Cover or cordon off adjacent parts which are electrically live.
- Release for work.
- Connect the PE conductor to
Assembly requirements
Warning of motor damage!
Connecting the motor directly to a three-phase system will destroy it.
Motors may only be driven with configured converters!
Ensure that the phase sequence is correct.
Encoder systems and temperature sensor contain electrostatically
endangered components (EEC).
Do not touch the connections with your hands or tools which could be
electrostatically charged!
Pre-assembled cables from SIEMENS are recommended (not included in scope of delivery).
These cables reduce the assembly time and increase operational safety
(see project planning instructions).
- Proper installation is the responsibility of the manufacturer of the system / machine.
- Observe the data on the type plate (Section 3.1) and the information in the wiring
diagrams (Fig. 5).
- Connecting leads must be suitable for the type of application and for the anticipated
currents and voltages.
- If the motor is supplied by means of converters, high-frequency current and voltage
harmonics in the motor supply leads can cause electromagnetic interference to be
emitted.
Use shielded power and signal lines.
Observe the EMC instructions of the converter manufacturer.
- The inside of the plug must be kept clean and free from cable residues and moisture.
- Avoid protruding wire ends.
- Check the seals and sealing surfaces of plug to ensure that the degree of protection is
maintained.
- The connecting leads are to be equipped with the strain relief device and the devices
which protect against rotation and transverse forces, and must be prevented from
kinking. The plugs 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, and the union nut 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. i²t monitoring.
