However, some of functions other thanthe basic functions such as RUN/STOP, Temperature Setting, etc. may not workproperly and may have a mismatch between the display and the actual behavior.2Wiring connection between the interface and the superlink E board.Interface sideSuperlink E boardNo. Names of recommended signal wires1 Shielded wireTerminalTerminalblock for YY2 Vinyl cabtyre round cordblock forSuper link3 Vinyl cabtyre round cableiterfaceE board XX4 Vinyl insulated wirevinyl sheathed cable for controlWithin 200 m 0.5 mm 2 2 coresWithin 300 m 0.75 mm 2 2 coresWithin 400 m 1.25 mm 2 2 coresWithin 600 m 2.0 mm 2 2 cores3Clamp the connection cables with cable clamps.- 233 -
