Safety instructions for Sensor Modules Cabinet-Mounted

Danger to life if the fundamental safety instructions and residual risks are not heeded
Failure to heed the fundamental safety instructions and residual risks in Chapter 1 can
result in accidents causing severe injuries or death.
• Follow the fundamental safety instructions.
• Consider the residual risks on the risk assessment.
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
• When using direct measuring systems (third-party encoders), ask the manufacturer
Danger to life due to fire if overheating occurs because of insufficient ventilation clearances
Inadequate ventilation clearances can cause overheating of components with subsequent
fire and smoke. This can cause severe injury or even death. Further, increased failures can
occur and the service life of units/systems may be shortened.
• For this reason, ensure the 50-mm ventilation clearances above and below the Sensor
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.
