For manufacturer setting. Do not use.
CAUTION
Do not use the empty terminals (NC) of the control circuit. Doing so may lead to damage of the converter unit and the
inverter.
Always connect the terminal RDA of the converter unit and the terminal MRS (X10) of the inverter, and the terminal SE
of the converter unit and the terminal PC (terminal SD in the sink logic) of the inverter. Not doing so may lead to damage
of the converter unit.
2.4.2 Wiring method
Power supply connection
For the control circuit wiring, strip off the sheath of a cable, and use it with a blade terminal. For a single wire, strip off the
sheath of the wire and apply directly. Insert the blade terminal or the single wire into a socket of the terminal.
(1) Strip off the sheath for the below length. If the length of the sheath peeled is too long, a short circuit may occur with
neighbouring wires. If the length is too short, wires might come off.
Wire the stripped cable after twisting it to prevent it from becoming loose. In addition, do not solder it.
(2) Insert wires into a blade terminal, then crimp the terminal.
Insert wires to a blade terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve.
Check the condition of the blade terminal after crimping. Do not use a blade terminal of which the crimping is
inappropriate, or the face is damaged.
