CAUTION
Do not see directly the light generated from SSCNET connector of servo amplifier or
QD75MH. When the light gets into eye, may feel something is wrong for eye.
(The light source of SSCNET corresponds to class1 defined in JISC6802 or IEC60825-1.)
If SSCNET cable is added a power such as a major shock, lateral pressure, haul, sudden
bending or twist, its inside distorts or breaks, and optical transmission will not be available.
SSCNET cable should be given loose slack to avoid from becoming smaller than the
minimum bend radius, and it should not be twisted.
Make sure to use SSCNET cable within the range of operating temperature described in this
manual. The optical cable and code part melts down if being left near the fire or high
temperature.
Therefore, do not make it touched the part which becomes high temperature, such as radiator
or regenerative brake option of servo amplifier, or servomotor.
Make sure to lay SSCNET cable with greater radius than the minimum bend radius.
(Refer to the Section 4.2.1 Precautions for SSCNET cable wiring.)
Fix the optical cable at the closest part to the connector with bundle material in order to prevent
SSCNET cable from putting its own weight on SSCNET connector.
Never use vinyl tape for optical cord. Plasticizing material in vinyl tape goes into optical fiber
and lowers the optical characteristic. At worst, it may cause wire breakage. If using adhesive
tape for the optical cable laying, the fire resistant acetate cloth adhesive tape 570F (Teraoka
Seisakusho Co., Ltd) is recommended.
If laying with other wires, do not make the optical cable touched wires or cables made from soft
polyvinyl chloride (PVC), polyethylene resin (PE), teflon (Fluorocarbon resin) or nylon which
contains plasticizing material.
If the adhesion of solvent and oil to the code part of SSCNET cable may lower the optical
characteristic and machine characteristic. If it is used such an environment, be sure to do the
protection measures to the optical cord.
When storing, put a cap on the connector part for preventing the connector edge of SSCNET
from getting dirt, dust and so on.
SSCNET connector is put a cap to protect light device inside connector from dust.
For this reason, do not remove a cap until just before mounting SSCNET cable.
Then, when removing SSCNET cable, make sure to put a cap.
Keep the cap for SSCNET connector and the tube for protecting light code end of SSCNET
cable in a plastic bag with a zipper of SSCNET cable to prevent them from becoming dirty.
When changing the servo amplifier or QD75MH, make sure to put cap on SSCNET
connector. When asking repair of servo amplifier for some troubles, make sure to put a cap on
SSCNET connector.
When the connector is not put a cap, the light device may be damaged at the transit.
In this case, exchange and repair of light device is required.
