238 Operating Instructions, 12/2018, A5E34763375A
Non-observance of the safety instructions
If the safety instructions in Chapter 1 are not observed, accidents can occur involving
severe injuries or death.
• Make sure that the safety instructions are observed.
Fire through overheating due to insufficient ventilation clearances
Inadequate ventilation clearances cause overheating with a risk for personnel due to smoke
and fire. This can also result in more downtimes and reduced service lives of the Terminal
Module.
• For this reason, it is imperative that you maintain the 50 mm clearances above and
below the Terminal Module.
Device failure as a result of 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 result in
significant disturbance of all signals (fault messages) up to failure of individual components
(destruction of the devices).
• Only use shielded cables as temperature sensor cables.
• If temperature sensor cables are routed together with the motor cable, use separately
shielded cables twisted in pairs.
• Connect the cable shield at both ends to ground potential over a large surface area.
Damage through the use of incorrect DRIVE-CLiQ cables
Damage or malfunctions can occur on the devices or system when incorrect or unreleased
DRIVE-CLiQ cables are used.
• Only use suitable DRIVE-CLiQ cables that have been released by Siemens for the
respective application.
Note
Malfunctions due to polluted DRIVE-CLiQ interfaces
Malfunctions can occur in the system through the use of polluted DRIVE
-CLiQ interfaces.
Cover unused DRIVE-CLiQ interfaces with the supplied blanking covers.
