●Product handling
∗Installation
•Tighten to the specified tightening torque.
If the tightening torque is exceeded the mounting screws, brackets and the product can be broken. Insufficient
torque can cause displacement of the product from its proper position and the looseness of the mounting screws.
(Refer to "Mounting and Installation" on page 16.)
•Be sure to ground terminal FG when using a commercially available switch-mode power supply.
•Do not use in a place subject to heavy vibration and/or shock.
Otherwise damage to the internal parts can result, causing malfunction.
•Do not pull the lead wire forcefully, not lift the product by pulling the lead wire. (Tensile force 30 N or
less)
Hold the body when handling to avoid the damage of the product.
The product will be damaged, leading to failure and malfunction.
•Never mount the product in a location that will be used as a scaffold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
∗Wiring
•Do not pull the lead wires. In particular, never lift a product equipped with fitting and piping by holding the
lead wires.
Otherwise damage to the internal parts can result, causing malfunction or disconnection from the connector.
•Avoid repeatedly bending, stretching or applying a heavy object or force to the lead wire.
Repetitive bending or tensile stress can cause the sheath of the wire to peel off, or break the wire.
If the lead wire can move, fix it near the body of 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 a damaged lead wire with a new one.
•Wire correctly.
Incorrect wiring can break the product.
•Do not perform wiring while the power is on.
Otherwise damage to the internal parts can result, causing malfunction.
•Do not route wires and cables together with power or high voltage cables.
Otherwise the product can malfunction due to interference of noise and surge voltage from power and high voltage
cables to the signal line. Route the wires (piping) of the product separately from power or high voltage cables.
•Confirm proper insulation of wiring.
Poor insulation (interference from another circuit, poor insulation between terminals, etc.) can lead to excess
voltage or current being applied to the product, causing damage.
•Keep wiring as short as possible to prevent interference from electromagnetic noise and surge voltage.
Do not use a cable longer than 30 m.
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 this product.
