Note 1: Use double-isolation cables for the contact output line (AC).
Double-isolate either contact output line (AC) or (DC) if they are mixed.
Note 2: Use MKKDSN series terminals (manufactured by Phoenix Contact Ltd.) for the protection system, and
FKC series terminals (manufactured by Phoenix Contact Ltd.) for the electric circuit except for the power
or Ethernet line. For these wiring connections, use AI series crimp-on terminals manufactured by the
same company. Four types of crimp-on terminals are used according to the wire diameters (see Table
2.5).
