DANGER!
Electric shock
The motor is operated with a dangerous voltage. Touching certain conducting components (connection terminals
and supply cables) will cause electric shock with possibly fatal consequences.
Even when the motor is at a standstill (e.g. due to the electronic block of a connected frequency inverter or a
jammed drive unit) the connection terminals and supply cables may carry a dangerous voltage. A motor standstill
is not identical to electrical isolation from the mains.
Even if the drive unit has been disconnected from the mains, a connected motor may rotate and possibly generate
a dangerous voltage.
Installation and work must only be carried out when the motor is at a standstill and is disconnected (all phases
disconnected from the mains).
Follow the 5 Safety Rules (1. Switch off the power, 2. Secure against switching on, 3. Check for no voltage, 4.
Earthing and short circuiting, 5. Cover or fence off neighbouring live components).

4.2 Connection
Notice! Hazardous voltages occur at the motor terminals when the motor shaft is rotating!
The motors must only be operated with suitable inverters For energy-efficient operation, the inverter
must detect the position of the rotor. Various methods both with and without encoders are available for
this. See also TI80_0010
Motors are normally supplied with a star circuit. Some operating points can only be used in a delta
circuit. For this, the bridges must be changed according to the circuit diagram in the terminal box cover.
