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

ƔVerify that the supply voltage variation is within the rating.
ƔIf 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.
ƔIn 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.
