Warning!
• Risk of electric shock. Switch off the power supply before opening the device.
Do not install or wire the device while it is connected to the power supply.
Failure to comply with this precaution can result in irreparable damage to parts of the electronics.
• Risk of electric shock. Connect the protective ground to the ground terminal on the housing
before the power supply is applied.
• You may only connect the sensor to the transmitter with the same serial number. Communication
errors can occur if this is not observed when connecting the devices.
