Safety instructions for Sensor Modules Cabinet-Mounted

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
• When using direct measuring systems (third-party encoders), ask the manufacturer
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
The use of incorrect or not released DRIVE-CLiQ cables can cause damage or functional
faults to devices or the system.
• Only use suitable DRIVE-CLiQ cables that have been approved by Siemens for the
Note
Diminished level of interference immunity due to equalizing currents via the electronics
ground
Ensure that there is no electrical connection between the encoder system housing and the
signal cables, or the encoder system electronics. If this is not carefully observed, the system
may not be able to reach the required interference immunity level. (There is then a danger of
equalization currents flowing through the electronics ground.)
