Electromagnetic Compatibility - Siemens 1LA8 Operating Instructions Manual

Safety information
2.9 Influence on the line power supply through a strongly irregular torque
Risk of explosion due to electrostatic discharge
Electrostatic discharge poses a potential ignition source. In an explosive atmosphere, there
is a risk of an explosion. This can result in death, serious injury or material damage.
Please comply with ESD protective measures.
2.7

Electromagnetic compatibility

This machine is designed in accordance with IEC/EN 60034 and when used as prescribed it
satisfies the requirements of European Directive 2004/108/EC on Electromagnetic
Compatibility.
2.8 Interference immunity
The machine fulfills the requirements regarding interference immunity in accordance with IEC/
EN 61000‑6‑2.
For machines with integrated sensors (e.g. PTC thermistors), the manufacturer of the complete
system must ensure sufficient interference immunity by selecting suitable sensor signal leads
and evaluation units.
2.9 Influence on the line power supply through a strongly irregular torque
A strongly irregular torque, for example with the drive of a reciprocating motor, forces a non-
sinusoidal motor current. The emerging harmonics can have an impermissible influence on
the line power supply via the connection lines.
