Mitsubishi FX3U-20SSC-H User Manual page 5

• Put the SSCNET III cable in the duct or fix the cable at the closest part to the 20SSC-H with bundle material in order
to prevent SSCNET III cable from putting its own weight on SSCNET III connector. When laying cable, the optical
cord should be given loose slack to avoid from becoming smaller than the minimum bend radius, and it should not
be twisted.
Also, fix and hold it in position with using cushioning such as sponge or rubber which does not contain plasticizing
material.
When using adhesive tape to bundle, use flame-resistant acetate cloth adhesive tape (e.g. 570F by Teraoka
Seisakusho Co., Ltd.).
• Migrating plasticizer is used for vinyl tape. Keep the MR-J3BUS
tape because the optical characteristic may be affected.
Generally, soft polyvinyl chloride (PVC), polyethylene resin (PE) and fluorine resin contain non-migrating plasticizer
and they do not affect the optical characteristic of SSCNET III cable. However, some wire sheaths and cable ties,
which contain migrating plasticizer (phthalate ester), may affect MR-J3BUS
In addition, MR-J3BUS M-B cable is not affected by plasticizer.
• Exposing the SSCNET III cable to solvent/oil may deteriorate the optical fiber and alter its mechanical
characteristics. When using the SSCNET III cable near solvent/oil, take protective measures to shield the SSCNET
III cable.
• When storing the SSCNET III cable, attach the protective cap to the 20SSC-H connector port for dust protection
• Do not remove the protective cap from the 20SSC-H connector port until just before connecting the SSCNET III
cable. Attach the protective cap to the 20SSC-H connector port after removing the SSCNET III cable to protect the
internal optical device from exposure to dust.
• Keep the protective cap and protective tubing clean, and always store them in the provided plastic bag when
removing them from the hardware devices.
• When replacing the 20SSC-H, or when sending the product to a local distributor for repair, make sure to attach the
protective cap to the 20SSC-H connector port. Failure to do so may damage the internal optical device and require
optical device replacement.
4. STARTUP AND MAINTENANCE PRECAUTIONS
• Do not touch any terminal while the PLC's power is on.
Doing so may cause electric shock or malfunctions.
• Before cleaning or retightening terminals, cut off all phases of the power supply externally.
Failure to do so may cause electric shock.
• Before modifying or disrupting the program in operation or running the PLC, carefully read through this manual and
the associated manuals and ensure the safety of the operation.
An operation error may damage the machinery or cause accidents.
• Before operating the Zero-return/JOG or testing of the positioning data, carefully read through this manual and the
associated manuals and ensure the safety of the operation.
An operation error may damage the machinery or cause accidents.
• Do not disassemble or modify the PLC.
Doing so may cause fire, equipment failures, or malfunctions.
For repair, contact your local Mitsubishi Electric representative.
• Turn off the power to the PLC before connecting or disconnecting any extension cable.
Failure to do so may cause equipment failures or malfunctions.
• Turn off the power to the PLC before attaching or detaching the following devices.
Failure to do so may cause equipment failures or malfunctions.
- Peripheral devices, expansion boards, and special adapters
- Extension units/blocks and FX Series terminal blocks.
5. DISPOSAL PRECAUTIONS
• Please contact a certified electronic waste disposal company for the environmentally safe recycling and disposal of
your device.
