[Precautions for Power Supply Wiring]
• Connect round crimp-style terminals provided with insulation
sleeves to the terminal block for power supply.
Be sure to follow the instructions provided below if the spec-
ified terminals cannot be used.
Otherwise, abnormal heat may be generated as a result
of the loosening of the wires.
• If stranded wires are used, do not solder the front end of the
wires.
• Connect proper wires securely and fix the wires so that exter-
nal force will not be imposed on the terminals.
• Use an appropriate screwdriver to tighten the terminal
screws. The screw heads may be damaged if the screwdriver
is too small and the terminal screws will not be tightened
properly.
• Do not tighten the terminal screws excessively, or otherwise
the screw heads may be damaged.
• Refer to the table below for the required tightening torque val-
ues of the terminal screws.
