If sensors are mounted close together and the ambient temperature is near the maxi-
mum rated value, provide for enough heat radiation / ventilation.
Make sure to carry out wiring in the power supply OFF condition.
Take care that wrong wiring will damage the sensor.
Verify that the supply voltage variation is within the rating.
If power is supplied from a commercial switching regulator, ensure that the frame ground
(F.G.) terminal of the power supply is connected to an actual ground.
In case noise generating equipment (switching regulator, inverter motor, etc.) is used in
the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to
an actual ground.
Do not run the wires together with high-voltage lines or power lines or put them in the
same raceway. This can cause malfunction due to induction.
Do not use during the initial transient time (50ms) after the power supply is switched
