2. INSTALLATION
(4) Bundle fixing
Fix the cable at the closest part to the connector with bundle material in order to prevent SSCNET
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 using adhesive tape for bundling the cable, fire resistant acetate cloth adhesive tape 570F (Teraoka
Seisakusho Co., Ltd) is recommended.

(5) Tension
If tension is added on optical cable, the increase of transmission loss occurs because of external force
which concentrates on the fixing part of optical fiber or the connecting part of optical connector. At worst,
the breakage of optical fiber or damage of optical connector may occur. For cable laying, handle without
putting forced tension. For the tension strength, refer to section 11.1.5.
(6) Lateral pressure
If lateral pressure is added on optical cable, the optical cable itself distorts, internal optical fiber gets
stressed, and then transmission loss will increase. At worst, the breakage of optical cable may occur. As
the same condition also occurs at cable laying, do not tighten up optical cable with a thing such as nylon
band (TY-RAP).
Do not trample it down or tuck it down with the door of control box or others.
(7) Twisting
If optical fiber is twisted, it will become the same stress added condition as when local lateral pressure or
bend is added. Consequently, transmission loss increases, and the breakage of optical fiber may occur at
worst.
(8) Disposal
When incinerating optical cable (cord) used for SSCNET
, hydrogen fluoride gas or hydrogen chloride gas
which is corrosive and harmful may be generated. For disposal of optical fiber, request for specialized
industrial waste disposal services who has incineration facility for disposing hydrogen fluoride gas or
hydrogen chloride gas.
