1. Attachments
• To be used in environments stipulated in the catalogue and in this document.
Usage in environments that subject the equipment to high temperatures, high humidity,
dirt and dust, corrosive gas, vibrations and shocks may result in electric shocks, the
outbreak of fire and malfunctions.
• Ensure that all attachments are made in accordance with the instructions provided in the
instruction manual. If the attachment procedures are ill-prepared, it may result in
dropped equipment, damage and malfunctions.
• Ensure that cable clippings and other foreign objects do not enter the equipment. Failure
to observe this may result in the outbreak of fire, damage and malfunctions.
2. Wiring
• Ensure that the equipment is connected to a rated power supply.
Connecting the equipment to non-rated power supplies may result in the outbreak of fire.
• Ensure that all wiring procedures are performed by qualified technicians.
Wrong wiring may result in the outbreak of fire, damage and electric shocks.
• Ensure that the coaxial cable is shielded when installing the link module.
As only one side of the shielded cable is to be earthed as a basic principle, attach the
earth to the RXD (receiving side.)
• Cover coaxial cables for transmitting between CPU link modules with cloth using a different route than
that used by other dynamic or signal cables. If it is not possible to establish a different route, use metal
pipes when connecting the wiring.
3. Maintenance
• Never dismantle or remodel the equipment.
Failure to observe this may result in the outbreak of fire, damage and malfunctions.
• Ensure that the power supply to the modules and units that are to be disconnected has
been switched off.
Failure to observe this may result in electric shocks, malfunctions and damage.
