•For the main circuit terminals, always use insulated electrical wires with a rated voltage of 600 V and a rated
temperature of 80°C or higher.
•Use the crimp-type terminal with an insulating sleeve to connect to the terminals.
•Up to two wires can be connected to one terminal.
•To prevent possible voltage drops, increase the wire size in accordance with the cable length.
•To connect the 100-V or 200-V model to the relay output terminal block, use a wire of 0.75 mm
•To connect seven wires or more to the control circuit terminal block, use a shield line of 0.5 mm
•Strip the signal line by 5 to 6 mm, and connect the exposed wire. (In the case of stranded wires, make sure that
the wires are not unraveled.)
•Make sure that the maximum outside coating diameter of the signal line is 2.0 mm or less (except for the alarm
signal line). (For the mark tube mounted cable and multi-core cable, keep both the mark tube and the sheath-
stripped length 40 mm or more from the connecting end. A thick line may prevent proper closing of the cover of
the terminal block.)
•To meet UL standards, always insert a UL-standard fuse (J type) on the power supply side.
•Use a ground wire with a larger diameter than that of the power cable shown above.
