(4) Twisting
If the SSCNET cable 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 SSCNET
cable may
occur at worst.
(5) Disposal
When incinerating optical cable (cord) used for SSCNET cable, hydrogen
fluoride gas or hydrogen chloride gas which is corrosive and harmful may
be generated. For disposal of SSCNET
cable, request for specialized
industrial waste disposal services who has incineration facility for disposing
hydrogen fluoride gas or hydrogen chloride gas.
(6) Wiring process of SSCNET cable
Put the SSCNET cable in the duct or fix the cable at the closest part to
the QD77MS with bundle material in order to prevent SSCNET
cable
from putting its own weight on SSCNET
connector. Leave the following
space for wiring.
• Putting in the duct
70mm
(2.76inch)
or more
5mm(0.20inch)
or more
Panel
98mm
(3.86inch)
30mm
(1.18inch)
or more
(Note-1)
80mm
(3.15inch)
or more
5mm(0.20inch)
or more
(Note-2)
Top of panel or wiring duct
QD77MS
Base unit

(Note-1): For wiring duct with 50[mm] (1.97 inch) or less height.
40[mm] (1.58 inch) or more for other cases.
(Note-2): 20mm (0.79inch) or more when the adjacent module is not removed and the extension cable is connected.
