(Note-1): 20mm (0.79inch) or more when the adjacent module is not removed and the extension cable is connected.
(Note-2): Q173DSCPU/Q172DSCPU use
(c) Lateral pressure
If lateral pressure is added on the SSCNET cable, the cable itself distorts,
internal optical fiber gets stressed, and then transmission loss will increase.
At worst, the breakage of SSCNET cable may occur. As the same
condition also occurs at cable laying, do not tighten up SSCNET cable
with a thing such as nylon band (TY-RAP).
Do not trample it down or tuck it down with the door of control panel or
others.
(d) Twisting
If 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.
(e) 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.
(f) Wiring process of SSCNET
Put the SSCNET cable in the duct or fix the cable at the closest part to
the Motion CPU module with bundle material in order to prevent SSCNET
cable from putting its own weight on SSCNET connector.
Leave the following space for wiring.
