NOTICE
Be sure to obser e these precautions to ensure safe use.
Do not use the product in places where explosi e or flammable gases may be present.
Ne er disassemble, repair or modify the product.
Tighten the terminal screws properly.
Use the specified size of solderless terminals for wiring.
Use the product within the rated supply oltage.
Use the product within the rated load.
The life expectancy of the output relay aries considerably according to its switching capacity and
operating conditions. Be sure to use the output relay within its rated load and electrical life expecĆ
tomcy. If the output relay is used beyond its life expectancy, its contacts may become fused or burned.
If you remo e the controller from its case, ne er touch nor apply shock to the electronic parts inside.
Do not co er the E5CKĆT. (Ensure sufficient space around the controller to allow heat radiation.)
Do not use the controller in the following places:
ÕPlaces subject to icing, condensation, dust, corrosi e gas (especially sulfide gas or ammonia gas).
ÕPlaces subject ibration and large shocks.
ÕPlaces subject to splashing liquid or oil atmosphere.
ÕPlaces subject to intense temperature changes.
ÕPlaces subject to heat radiation from a furnace.
Be sure to wire properly with correct polarity of terminals.
When wiring input or output lines to your controller, keep the following points in mind to reduce the
influence from inducti e noise:
ÕAllow adequate space between the high oltage/current power lines and the input/output lines.
ÕA oid parallel or common wiring with high oltage sources and power lines carrying large currents.
ÕUsing separating pipes, ducts, and shielded line is also useful in protecting the controller, and its
lines from inducti e noise.
Cleaning: Do not use paint thinner or organic sol ents. Use standard grade alcohol to clean the prodĆ
uct.
Use a oltage (100 to 240 VAC at 50 to 60 Hz). At power ON, the prescribed oltage le el must be
attained within two seconds.
Allow as much space as possible between the controller and de ices that generate a powerful high
frequency (highĆfrequency welders, highĆfrequency sewing machines, etc.) or surge. These de ices
may cause malfunctions.
If there is a large powerĆgenerating peripheral de ice and any of its lines near the controller, attach
a surge suppressor or noise filter to the de ice to stop the noise affecting the controller system. In
particular, motors, transformers, solenoids and magnetic coils ha e an inductance component, and
therefore can generate ery strong noise.
When mounting a noise filter on the power supply to the controller, be sure to first check the filter's
oltage and current capacity, and then mount the filter as close as possible to the controller.
