Safety instructions for Sensor Modules Cabinet-Mounted

Danger to life if the fundamental safety instructions and residual risks are not observed
The non-observance of the fundamental safety instructions and residual risks stated in
Chapter 1 can result in accidents with severe injuries or death.
• Observe the fundamental safety instructions.
• Consider the residual risks for the risk evaluation.
Danger to life due to electric shock when disconnecting and connecting encoder cables
during operation
When opening plug connections in operation, arcs can result in severe injury or death.
• Disconnect or connect the encoder cables to Siemens motors, which are not expressly
NOTICE
Damage when connecting an impermissible number of encoder systems
If more than the maximum permissible number of encoder systems are connected to a
Sensor Module, this will cause damage.
• Only connect one encoder system per Sensor Module.
NOTICE
Damage caused by the use of incorrect DRIVE-CLiQ cables
Damage or malfunctions can occur on the devices or system when DRIVE-CLiQ cables are
used that are either incorrect or have not been approved for this purpose.
• Only use suitable DRIVE-CLiQ cables that have been approved by Siemens for the
