Wiring (Including connecting/disconnecting of the connectors)
•Do not pull hard on the lead wire.
Especially never lift the product equipped with fitting and piping by holding the lead wires.
Otherwise damage to the internal components may result, causing malfunction or connectors dropping off.
•Avoid repeatedly bending, stretching or applying a heavy object to the lead wire.
Repetitive bending stress or tensile stress can cause the sheath of the wire to peel off, or breakage of the wire.
If the lead wire can move, fix it near the product.
The recommended bend radius of the lead wire is 6 times the outside diameter of the sheath, or 33 times the
outside diameter of the insulation material, whichever is larger.
Replace the damaged lead wire with a new one.
•Wire correctly.
Incorrect wiring may cause malfunction or damage to the product.
•Do not perform wiring while the power is on.
Otherwise damage to the internal components may result, causing malfunction.
•Do not route wires and cables together with power or high voltage cables.
Route the wires of the product separately from power or high voltage cables to prevent noise and surge of signal
lines from entering the product.
•Confirm correct insulation of wiring.
Poor insulation (interference with other circuits, poor insulation between terminals, etc.) can apply excessive voltage
or current to the product causing damage.
•Keep wiring as short as possible to prevent interference from noise and surge voltage.
Wire the DC(-) line(blue) as close as possible to the power supply.
•When the analogue output is used, install a noise filter (line noise filter, ferrite element, etc.) between the
switch-mode power supply and the product.
