• 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.
