NOTE
o
Follow the instructions given below when designing, selecting and handling the product.
o
The instructions on design and selection (installation, wiring, environment, adjustment,
operation, maintenance, etc.) described below must also be followed.
o
Product specifications
▪
When conformity to UL is necessary the Serial Interface unit must be used with a
UL1310 Class2 power supply.
▪
The unit is an
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
o
Installation
▪
Do not drop, hit or apply excessive shock to the Ethernet ITV 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.
▪
IP65 protection cannot be guaranteed if the screws are not tightened to the specified
torque.
▪
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.
o
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.
▪
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.
