Note 1. The dimension of the main circuit terminal is a dimension for board
conductor wiring. (See the right diagram) The board conductor
thickness (D dimension) must be below the allowable connection
conductor thickness stated above because of the length of the
terminal screw. In case of wiring with two boards used, the total
value of two boards must be below the value (D dimension) shown in
the table.
Note 2. In each terminal, two wires or two solderless terminals are allowed to
be connected.
Note 3. The cross slot screw with pressure plate of T Series and N Series are same in size but different in
pressure plate dimension, so please avoid the mixed use of such screws. This may break the
insulation barrier or make the wire likely to fall out.
Note 4. When using IEC60529-based finger safe specification, be sure to use an insulation tube-attached
solderless terminal.
Note 5. Tightening the3 terminal screw excessively without wiring may break the screw and consequently
disable the tightening, so please avoid such excessive tightening.
Note 6. Operational circuits are coil terminals of magnetic contactors and control circuit terminals of
Thermal Overload Relays.
Note 7. Please use swaging tool which is recommended by JST.
Note 8. For the auxiliary a fixed contact elements of the S-T21 and T25 types, these elements could drop
off if its terminal screw is tightened with a screwdriver tilted towards the unit body. Do not tilt the
screwdriver towards the unit body when tightening the screw.
