Fundamental safety instructions
1.1 General safety instructions
NOTICE
Damage to motor insulation due to excessive voltages
When operated on systems with grounded line conductor or in the event of a ground fault
in the IT system, the motor insulation can be damaged by the higher voltage to ground. If
you use motors that have insulation that is not designed for operation with grounded line
conductors, you must perform the following measures:
• IT system: Use a ground fault monitor and eliminate the fault as quickly as possible.
• TN or
Fire due to inadequate ventilation clearances
Inadequate ventilation clearances can cause overheating of components with subsequent
fire and smoke. This can cause severe injury or even death. This can also result in increased
downtime and reduced service lives for devices/systems.
• Ensure compliance with the specified minimum clearance as ventilation clearance for the
NOTICE
Overheating due to inadmissible mounting position
The device may overheat and therefore be damaged if mounted in an inadmissible position.
• Only operate the device in admissible mounting positions.
NOTICE
Device damage caused by incorrect voltage/insulation tests
Incorrect voltage/insulation tests can damage the device.
• Before carrying out a voltage/insulation check of the system/machine, disconnect the
Unexpected movement of machines caused by inactive safety functions
Inactive or non-adapted safety functions can trigger unexpected machine movements that
may result in serious injury or death.
• Observe the information in the appropriate product documentation before
• Carry out a safety inspection for functions relevant to safety on the entire system,
• Ensure that the safety functions used in your drives and automation tasks are adjusted
• Perform a function test.
• Only put your plant into live operation once you have guaranteed that the functions
