Safety instructions with respect to control cabinet design
Danger of injury caused by foreign objects in the device
Parts (e.g. drilling chips, end sleeves) falling into the device can cause short circuits and
damage the insulation. This can lead to serious injuries (arcing, loud bang, pieces flying out
of the equipment).
• Only perform installation and other work when the devices are safely isolated from the
power supply.
• Cover the ventilation slits during installation of the cabinet and remove the cover before
switching on.
Malfunctions and damage due to static discharge
If static discharge occurs on surfaces or interfaces that cannot be easily accessed, this can
cause malfunctions and/or defects.
• Only touch components, modules and devices if you are first grounded by applying one
of the following measures:
– Wearing an ESD wrist strap
Wearing ESD shoes or ESD grounding straps in ESD areas with conductive flooring
Notes on electromagnetic compatibility (EMC)
Requirements to implement EMC are listed in EN 61800-3 and in the "EMC Installation
Guideline" Configuration Manual (Article No. 6FC5297-0AD30-0.P.). Conformance with the
EMC Directive of the EC can be ensured by following the measures described in the
Configuration Manual, EMC installation guideline.
When mounting components in cabinets, in order to fulfill the EMC Directive, the following
conditions must be additionally observed:
● Operation on TN and TT line supply systems with grounded neutral point
● Observance of information about cable shielding and equipotential bonding
● Use of the recommended power and signal cables from Siemens
● Only cables from Siemens may be used for DRIVE-CLiQ connections
