In the system, the laser beam light runs through the optical cable.
The exposure of the laser beam on worker’s eye may cause serious injury so that it
should be handled with care.
Remove the cap of the optical connector before connecting.
- Before connecting the optical cable, check if the ferrule of the connector is soiled.
Be careful to keep the cutting section away from dust or foreign material.
If the cable is soiled with foreign material, do not blow to remove them.
- Make sure to clean the connector in accordance with the cleaning directions in
Annex.
- Do not touch the ferrule at the end of optical cable because it is easy to be
damaged.
Because L1 port is not used in Cascade end-oriented, assemble the cap at the L1
port to prevent foreign substances and do not remove the cap discretionally.
