Electrical Connection; Important Instructions - Siemens 1FT6 13 Instructions Manual

Cooling water flow temperature
To prevent condensation in the motor, the temperature of the cooling water must be equal
to or greater than the dew-point temperature of the environment.
Coolant
A corrosion inhibitor (e.g. Tyfocor, maximum 25%) is recommended.
If the cooling circuit has been filled and frost can be expected, a commercially available
antifreeze agent must be added. Please refer to the manufacturer's documentation for
usage and dosage (max. 25%). Do not mix different types of antifreeze!

Important instructions

Safety rules for working in electrical installations as per
EN 50110-1 (DIN VDE 0105-100):
- Always work 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 power supply 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 sensitive
components (ESD).
Do not touch the connections with your hands or tools which could be
electrostatically charged!

Electric shock hazard!
When the rotor is rotating, the motor terminals carry a voltage of
approx. 300 V.
Stop the motor before commencing any electrical work.
Only use trained, qualified personnel for assembly work on the
converter, terminal box and connector!
Observe the regulations for working in electrotechnical plants.
