Protective
measures
Keep a minimum distance of 20 cm from the control and its leads to
interfering equipment.
Keep a minimum distance of 10 cm from the control and its leads to cables
that carry interference signals. For cables in metallic ducting, adequate
decoupling can be achieved by using a grounded separation shield.
Shielding according to EN 50 178.
Use equipotential bonding conductors with a cross section of 6 mm
2
Use only genuine HEIDENHAIN cables, connectors and couplings
3.1.4 ESD protection
Always assume that all electronic components and assemblies are endan-
gered by electrostatic discharge (ESD).
To ensure protection from ESD, follow the precautionary measures described
in IEC 61340-5-1, IEC 61340-5-2 and IEC 61340-4-1.
The following are some points covered in the above mentioned standards:
When handling electrostatically endangered components or assemblies
(e.g. exchange, installation, shipping), always comply with the precautionary
measures described in IEC 61340-5-1, IEC 61340-5-2 and IEC 61340-4-1.
Store and transport ESD-sensitive components in ESD protective
containers.
Ensure during handling the proper grounding of the working area (e.g. tool,
workbench, packaging) and the person.
Inspect the ESD protection system regularly.
Improper handling can result in damage to the components or assemblies
due to ESD!
