Safety instructions for DMC20 DRIVE-CLiQ Hub Modules
Fire through overheating due to insufficient ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk for personnel due to
smoke and fire. This can also result in increased failure rates and a shorter service life for
Hub Modules.
• It is absolutely essential that you maintain ventilation clearances according to the table
Ventilation clearances above and below the component (Page 294).
Damage through use of incorrect DRIVE-CLiQ cables
Damage or malfunctions can occur on the devices or the system when incorrect or
unreleased DRIVE-CLiQ cables are used.
• Only use suitable DRIVE-CLiQ cables that have been approved by Siemens for the
particular application.
Note
Malfunctions due to soiled DRIVE-CLiQ interfaces
Malfunctions can occur in the system through the use of soiled DRIVE
-CLiQ interfaces.
Cover unused DRIVE-CLiQ interfaces with the supplied blanking covers.
Note
Function equipotential bonding for distributed DRIVE-CLiQ nodes
All components operated on the DRIVE
-CLiQ must be integrated into the equipotential
They should preferably be connected by installing them on bare metal machine parts
and
devices, which are all bonded to one another in an equipotential manner.
Alternatively, equipotential bonding can be achieved by means of a conductor (min. 6
mm²),
which should be routed parallel to the DRIVE
-CLiQ where possible. This involves all
tributed DRIVE-CLiQ participants.
