(1) Wire specifications and how to perform wiring
• Connect input lines from the outside to the terminals T
1
and T2 on the terminal block (6P) for remote controller to
achieve remote control.
•See “11. FIELD SETTING” for details on operation.
(2) Actuation
• The following table explains FORCED OFF and ON/OFF
