2 Safety instructions
Please observe the safety instructions in this documentation when you want to commission an
automation system or a plant with a Lenze Controller.
The device documentation contains safety instructions which must be observed!
Read the documentation supplied with the components of the automation system
carefully before you start commissioning the Controller and the connected devices.
Danger!
High electrical voltage
Injury to persons caused by dangerous electrical voltage
Possible consequences
Death or severe injuries
Protective measures
Switch off the voltage supply before working on the components of the automation
system.
After switching off the voltage supply, do not touch live device parts and power
terminals immediately because capacitors may be charged.
Observe the corresponding information plates on the device.
Danger!
Injury to persons
Risk of injury is caused by ...
• unpredictable motor movements (e.g. unintended direction of rotation, too high
velocities or jerky movement);
• impermissible operating states during the parameterisation while there is an active
online connection to the device.
Possible consequences
Death or severe injuries
Protective measures
• If required, provide systems with installed inverters with additional monitoring and
protective devices according to the safety regulations valid in each case (e.g. law on
technical equipment, regulations for the prevention of accidents).
• During commissioning, maintain an adequate safety distance to the motor or the
machine parts driven by the motor.
