Mitsubishi FX3U-20SSC-H User Manual page 5

• Make sure to lay SSCNET III cable with greater radius than the minimum bend radius. (Refer to the Section 5.4.1
Precautions for SSCNET III cable wiring.)
• Fix the optical cable at the closest part to the connector with bundle material in order to prevent SSCNET III cable
from putting its own weight on SSCNET III connector.
• Never use vinyl tape for optical cord. Plasticizing material in vinyl tape goes into optical fiber and lowers the optical
characteristic. At worst, it may cause wire breakage. If using adhesive tape for the optical cable laying, the fire
resistant acetate cloth adhesive tape 570F (Teraoka Seisakusho Co., Ltd) is recommended.
If laying with other wires, do not make the optical cable touched wires or cables made from soft polyvinyl chloride
(PVC), polyethylene resin (PE), teflon (Fluorocarbon resin) or nylon which contains plasticizing material.
• If the adhesion of solvent and oil to the code part of SSCNET III cable may lower the optical characteristic and
machine characteristic. If it is used such an environment, be sure to do the protection measures to the optical cord.
• When storing, put a cap on the connector part for preventing the connector edge of SSCNET III from getting dirt,
dust and so on.
• SSCNET III connector is put a cap to protect light device inside connector from dust.
For this reason, do not remove a cap until just before mounting SSCNET III cable.
Then, when removing SSCNET III cable, make sure to put a cap.
• Keep the cap for SSCNET III connector and the tube for protecting light code end of SSCNET cable in a plastic bag
with a zipper of SSCNET III cable to prevent them from becoming dirty.
• When changing the servo amplifier or 20SSC-H, make sure to put cap on SSCNET III connector. When asking
repair of servo amplifier for some troubles, make sure to put a cap on SSCNET III connector.
When the connector is not put a cap, the light device may be damaged at the transit.
In this case, exchange and repair of light device is required.
4. STARTUP AND MAINTENANCE PRECAUTIONS
• Do not touch any terminal while the PLC's power is on.
Doing so may cause electrical shock or malfunctions.
• Before cleaning or retightening terminals, externally cut off all phases of the power supply.
Failure to do so may expose you to shock hazard.
• Before modifying the program under operation or performing operation for forcible output, running or stopping,
carefully read the manual, and sufficiently ensure the safety.
An operation error may damage the machine or cause accidents.
• To test Zero-return, JOG operation and Positioning data, throughly read this manual, ensure the safe system
operation
An operation error may damage the machine or cause accidents.
• Do not disassemble or modify the PLC.
Doing so may cause failures, malfunctions or fire.
For repair, contact your local Mitsubishi Electric distributor.
• Before connecting or disconnecting any extension cable, turn off power.
Failure to do so may cause unit failure or malfunctions.
• Before attaching or detaching the following devices, turn off power.
Failure to do so may cause device failure or malfunctions.
- Peripheral devices, expansion boards and special adapters
- I/O extension blocks/units and terminal blocks
5. DISPOSAL PRECAUTIONS
• Please contact a company certified in the disposal of electronic waste for environmentally safe recycling and
disposal of your device.
