Ɣ
Take care that short-circuit of the load or wrong wiring may burn or damage the
product.
Ɣ
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.

Verify that the supply voltage variation is within the rating.
Ɣ
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.
Ɣ
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.
