WARNING
Electric shock caused by defective cables
Defective connection cables can cause an electric shock and/or material damage, e.g. by re.
• When installing the motor, make sure that the connection cables
– are not damaged
– are not under tension
– cannot come into contact with any rotating parts
• Note the permissible bending radii (see "Important data for 1FW6 cables (Page94)").
• Do not hold a motor by its cables.
• Do not pull the motor cables.
WARNING
Electrical shock hazard
Every movement of the rotor compared with the stator and vice versa induces a voltage at the
stator power connections.
When the motor is switched on, the stator power connections are also at a specic voltage.
If you use defective cable ports, you could suer an electric shock.
• Only mount and remove the electrical components if you are qualied to do so.
• Any work carried out at the motor must always be done with the system in a no-voltage
condition.
• Do not touch the cable ports. Correctly connect the stator power connections, or insulate
them properly.
• Do not disconnect the power connections when the stator is under voltage (live).
• Only use the specic power cables intended for the purpose.
• First connect the protective conductor (PE).
• Connect the cable shield through a wide area.
• First connect the power cable to the stator before you connect the power cable to the
inverter.
• First disconnect the connection to the inverter before you disconnect the power connection
to the stator.
• Disconnect the protective conductor PE last.
CAUTION
Risk of crushing when the rotor is installed
There is a risk of crushing when the rotor of an installed torque motor rotates!
• Wear safety gloves.
• Take extreme care when performing any work.
