DANGER
Risk of death, serious personal injury (electrical shock), and/or material damage if direct
drives are connected incorrectly.
Motors must be connected in accordance with the circuit diagram provided in this
Motors must be connected in accordance with the circuit diagram provided in this
documentation and require a sinusoidal current injection. They must not be connected
directly to the three-phase supply because this will damage them.
The motors are designed to be operated on drive systems that are supplied via power
The motors are designed to be operated on drive systems that are supplied via power
supply networks grounded with low resistance (TN systems).

DANGER
Components in electrical devices may be under hazardous voltage. There is an electrical
shock hazard!
When the rotor is rotating, a voltage is present at the motor terminals that increases
When the rotor is rotating, a voltage is present at the motor terminals that increases
proportionally with the speed. At no-load speed, the amplitude value of the voltage at the
motor terminals is the same as the voltage value of the converter DC link voltage.
All work involving the electrics must only be carried out by skilled personnel when the
All work involving the electrics must only be carried out by skilled personnel when the
device is disconnected from the power supply and the motor is at a standstill.
Note the regulations for working on electrical installations.
In particular, the following safety rules for working on electrical installations in accordance
Note the regulations for working on electrical installations.
In particular, the following safety rules for working on electrical installations in accordance
with EN 50110-1/BGV A3 must be observed:
Disconnect the system.
Protect against reconnection.
Make sure that the equipment is de-energized.
Ground and short-circuit.
Cover or enclose adjacent components that are still live.
Only work on electrical devices when they are de-energized. The protective conductor
should be the first thing to be connected and the last to be disconnected.
All PELV circuits must meet the requirements of electrical separation in accordance with
All PELV circuits must meet the requirements of electrical separation in accordance with
EN 61800-5-1.
WARNING
The connection block on the motor for the motor supply cables (power and signal cables)
must never be removed.
This could destroy the motor.
This could destroy the motor.
