NOTE
○Follow the instructions given below when designing, selecting and handling the product.
The instructions on design and selection
(installation, wiring, environment, adjustment, operation,
maintenance, etc.)
described below must also be followed.
Product specifications
When conformity to UL is necessary the SI unit must be used with a UL1310 Class2 power supply.
The SI unit is a UL approved product only if they have a
mark on the body.
Use the specified voltage.
Otherwise failure or malfunction can result.
Reserve a space for maintenance.
Allow sufficient space for maintenance when designing the system.
Do not remove any nameplates or labels.
This can lead to incorrect maintenance, or misreading of the operation manual, which could cause damage or
malfunction to the product.
It may also result in non-conformity to safety standards.
Product handling
Installation
Do not drop, hit or apply excessive shock to the fieldbus system.
Otherwise damage to the product can result, causing malfunction.
Tighten to the specified tightening torque.
If the tightening torque is exceeded the mounting screws may be broken.
Never mount a product in a location that will be used as a foothold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
Wiring
Avoid repeatedly bending or stretching the cables, or placing heavy load on them.
Repetitive bending stress or tensile stress can cause breakage of the cable.
Wire correctly.
Incorrect wiring can break the product.
Do not perform wiring while the power is on.
Otherwise damage to the fieldbus system and/or I/O device can result, causing malfunction.
Do not route wires and cables together with power or high voltage cables.
Otherwise the fieldbus system and/or I/O device 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 fieldbus system and/or I/O device 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.
Take appropriate measures against noise, such as using a noise filter, when the fieldbus system is
incorporated into equipment.
Otherwise noise can cause malfunction.
