3. Pressure weld the connector using a plier or the like.
• For pressure welding, make sure to apply the plier in parallel with the connector,
from the direction indicated below.
• Pay attention not to damage the wire with the plier while pressure welding.
• Make sure that the wire does not become loose while pressure welding.

Note: Take care that if the connector is pulled out without pressing the release lever, the release lever may break. Do
not use an input connector whose release lever has broken. Further, do not pull by holding the cable, as this can
cause a cable-break.

8 CAUTIONS
Ɣ This product has been developed / produced for industrial use only.
Ɣ Make sure that the power supply is OFF while wiring and adding the units.
Ɣ Take care that if a voltage exceeding the rated range is applied, or if an AC power
supply is directly connected, the product may get burnt or damaged.
Ɣ Make sure to check the wiring as wrong wiring can damage or burn 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.
Ɣ 7KHVSHFL¿FDWLRQPD\QRWEHVDWLV¿HGLQDVWURQJPDJQHWLF¿HOG
Ɣ 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 Take care that if noise is applied to the analogue voltage input, the product may
malfunction.
Ɣ Make sure to use an insulation transformer for DC power supply. If an auto-trans-
former (single winding transformer) is used, the main body or the power supply
may get damaged.
Ɣ In case a surge is generated in the used power supply, connect a surge absorber
to the supply and absorb the surge.
Ɣ Do not use the unit during the initial transient time (approx. 0.5 sec.) after the
power supply is switched on.
Ɣ In order to reduce noise, make the wiring as short as possible.
Ɣ This product is suitable for indoor use only.
Ɣ Avoid dust, dirt, and steam.
Ɣ Take care that the product does not come in contact with oil, grease, organic sol-
vents, such as thinner, etc., strong acid or alkaline.
