CAUTION
Please connect the SSCNET cable with the above-mentioned connector. When the connection is
mistaken, the communication between QD75MH and the servo amplifier cannot be done.
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.
