● Noise Countermeasures
Do not install the product near devices generating strong high-frequency waves or
surges, such as high-frequency welding and sewing machines.
(1) Mount a surge suppressor or noise filter to peripheral devices generating noise, in
particular, motors, transformers, solenoids, and magnet coils.
(2) In order to prevent inductive noise, wire the lines connected to the terminal block
separately from power lines carrying high voltages or currents. Do not wire in parallel with
or in the same cable as power lines. Other measures for reducing noise include running
lines along separate ducts and using shield lines.

(3) When using a noise filter, check the voltage and current and install it as close to the
product as possible.
(4) Reception interference may occur if the product is used close to a radio, television, or
wireless.
