※1. Do not mix noise to input cable.
It is recommended to use shield cable,
twisted cable as input cable for effective noise.
※2. If there is possible to affect inductive noise,
it is recommended to use shielded cable at high-frequency power for effective noise.
※3. DI input switch should be for low current and ON resistance should be max. 20Ω (including cable
resistance).
※4. DI input terminals are COM, DI-1 to 3, RUN, AUTO.
※5. For remote display unit option model,
use connection cable as our standard cable.
