*1 This terminal operates as terminal FM for the type FM inverter. For the type CA inverter, the terminal operates as terminal CA.
*2 The X10 signal is assigned to terminal MRS in the initial setting.
*3 No function is assigned in the initial setting.
 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
neighboring wires. If the length is too short, wires might come off.
Wire the stripped cable after twisting it to prevent it from becoming loose. Do not solder it.
2.
Crimp the blade 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.
Blade terminals commercially available (as of January 2017)
