Safety information

Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
If the fundamental safety instructions and remaining risks in Chapter 1 (Page 21) are not
observed, accidents involving severe injuries or death may occur.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account residual risks.
Fire hazard due to overheating because of inadequate 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
Note
All components operated on the DRIVE-CLiQ must be integrated into the equipotential
bonding concept.
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
distributed DRIVE-CLiQ participants.
