(Note 1) When selecting a manual pulse generator, make sure that its case and 0V terminal are insulated.
(Note 2) When connecting cables using a terminal block, etc., never fail to observe the followings.
- The total length of the cables from the connector on C80's side to the terminal area of manual pulse
generators has to be within the maximum cable length (20m).
- Have the cable shield single-point-grounded on C80's side, and cover the cable with the shield up to
near the manual pulse generators. (It is required to relay the shield also.)
- For relay cables, use wire material of cross section equivalent to UL1061-2464 AWG26 x 2P or above.
