(2) Prohibition of vinyl tape use
Migrating plasticizer is used for vinyl tape. Keep the MR-J3BUS_M, and MR-J3BUS_M-A cables away
from vinyl tape because the optical characteristic may be affected.

: Phthalate ester plasticizer such as DBP and DOP
may affect optical characteristic of cable.
: Cord and cable are not affected by plasticizer.
(3) Precautions for migrating plasticizer added materials
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_M
and MR-J3BUS_M-A cables.
In addition, MR-J3BUS_M-B cable is not affected by plasticizer.
A chemical substance may affect its optical characteristic. Therefore, previously check that the cable is
not affected by the environment.
(4) Bundle fixing
Fix the cable at the closest part to the connector with bundle material in order to prevent SSCNET III
cable from putting its own weight on CN1A/CN1B connector of servo amplifier. Optical cord should be
given loose slack to avoid from becoming smaller than the minimum bend radius, and it should not be
twisted.
When bundling the cable, fix and hold it in position by using cushioning such as sponge or rubber which
does not contain migratable plasticizers.
If adhesive tape for bundling the cable is used, fire resistant acetate cloth adhesive tape 570F (Teraoka
Seisakusho Co., Ltd) is recommended.
