• Do not mix noise to input cable. It is recommended to use shield cable, twisted cable as input cable for e󰀨ective noise.

• If there is possible to a󰀨ect inductive noise, it is recommended to use shielded cable at high-frequency power for e󰀨ective noise.

• DI input switch should be for low current and ON resistance should be max. 20Ω (including cable resistance).

• DI input terminals are COM, DI-1 to 3, RUN, AUTO.

• For remote display unit option model, use connection cable as our standard cable.

• When connecting ⑥, ⑪ , it operates as MANUAL. When connecting, ⑥, ⑦, ⑪, it operates AUTO.
