Connection
NOTICE
Couplings on the sensor cable
Sensor fault
Do not route the sensor cable close to high voltage power supplies.
Keep the length of the connection lines as short as possible.
Use shielded connection cables.
Keep the sensor cables away from high-power AC cables and motor drive cables.
Do not connect or disconnect the sensor when energized.
Route the high-voltage and low-voltage cables separately.
Connect the female connector of the connection cable to the male connector of the
device.
If the higher-level input is a differential (symmetrical) input, connect the sensor to the
higher level as shown in the figure.
If the higher-level input is a common ground (asymmetrical) input, connect the sensor to
the higher level as shown in the figure.
NOTE
Keep pin 2 potential-free during operation to prevent any accidental teach-in
operations.
