(3) Insert the wires into a socket.
NOTE
• When using stranded wires without a crimp terminal, twist enough to avoid short circuit with a nearby terminals or wires.
• Place the flathead screwdriver vertical to the open/close button. In case the blade tip slips, it may cause an inverter damage
or injury.
• Wire removal
Pull the wire while pushing the open/close button all
the way down firmly with a flathead screwdriver.
Common terminals of the control circuit (SD, PC, 5, SE)
• Terminals SD (sink logic), PC (source logic), 5, and SE are common terminals (0V) for I/O signals. (All common terminals
are isolated from each other.) Do not earth (ground) these terminals. Avoid connecting the terminal SD (sink logic) with 5,
the terminal PC (source logic) with 5, and the terminal SE with 5.
• In the sink logic, terminal SD is a common terminal for the contact input terminals (STF, STR, STP (STOP), RH, RM, RL,
JOG, RT, MRS, RES, AU, CS) and the pulse train output terminal (FM). The open collector circuit is isolated from the
internal control circuit by photocoupler.
• In the source logic, terminal PC is a common terminal for the contact input terminals (STF, STR, STP (STOP), RH, RM, RL,
JOG, RT, MRS, RES, AU, CS). The open collector circuit is isolated from the internal control circuit by photocoupler.
• Terminal 5 is a common terminal for the frequency setting terminals (2, 1 or 4) and the analog output terminals (AM). It
should be protected from external noise using a shielded or twisted cable.
• Terminal SE is a common terminal for the open collector output terminals (RUN, SU, OL, IPF, FU). The contact input circuit
is isolated from the internal control circuit by photocoupler.

INSTALLATION AND WIRING
Crimp terminal part No.
When using a single wire or stranded wires without a crimp terminal, push the
open/close button all the way down with a flathead screwdriver, and insert the
wire.
Open/close button
Flathead screwdriver
Insulation cap part No.
VC 0.75
NOTE
• Pulling out the wire forcefully without pushing the open/close
button all the way down may damage the terminal block.
• Use a small flathead screwdriver (tip thickness: 0.4 mm/tip
width: 2.5 mm).
If a flathead screwdriver with a narrow tip is used, terminal
block may be damaged.
