NOTICE
Damage to memory card due to electric fields or electrostatic discharge
Electrical fields or electrostatic discharge may result in the memory card being damaged.
• When removing and inserting the memory card, always observe the ESD regulations.
NOTICE
Risk of component destruction as a result of high leakage currents
The Control Unit or other PROFIBUS and/or PROFINET nodes can be destroyed if
substantial leakage currents flow through the PROFIBUS or PROFINET cable.
• Use a functional equipotential bonding conductor with a cross section of at least 25 mm²
NOTICE
Device failure due to unshielded or incorrectly routed cables to temperature sensors
Unshielded or incorrectly routed cables to temperature sensors can result in interference
being coupled into the signal processing electronics from the power side. This can
significantly disturb all signals (fault messages), evening causing individual components to
fail (destruction of the devices).
• Only use shielded cables as temperature sensor cables.
• If temperature sensor cables are routed together with the motor cable, use twisted-pair,
• Connect the cable shield at both ends to ground potential over a large surface area.
• Recommendation: Use suitable Motion Connect cables.
NOTICE
Damage caused by the use of unsuitable DRIVE-CLiQ cables
If unsuitable DRIVE-CLiQ cables are used, damage or malfunctions can occur in the
devices or the system itself.
• Use only appropriate DRIVE-CLiQ cables that have been approved by Siemens for the
Note
Functional faults caused by dirty DRIVE-CLiQ interfaces
Malfunctions can occur in the system due to use of dirty DRIVE-CLiQ interfaces.
• Close any unused DRIVE-CLiQ interfaces with the supplied cover plates.
