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
•
The direct current power supply to combine should be UL1310 Class2 power supply when conformity to
UL is necessary.
•
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.
•
Precautions on handling
*Installation
•
Do not drop, hit or apply excessive shock to the SI unit.
Otherwise damage to the product can result, causing malfunction.
•
Tighten to the specified tightening torque. (refer to page 13)
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 SI unit and/or I/O device can result, causing malfunction.
•
Do not route wires and cables together with power or high voltage cables.
Otherwise the SI unit 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 SI unit 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 SI unit is incorporated
into equipment.
Otherwise noise can cause malfunction.
