(3) Control circuit common terminals (SD, 5, SE)
Terminals SD, SE and 5 are common terminals for I/O signals. (All common terminals are isolated from each other.) Do not
earth them. Avoid connecting the terminals SD and 5 and the terminals SE and 5.
Terminal SD is a common terminal for the contact input terminals (STF, STR, RH, RM, RL, RES) and frequency output signal
(FM). The open collector circuit is isolated from the internal control circuit by photocoupler.
Terminal 5 is a common terminal for the frequency setting signals (terminal 2 or 4). It should be protected from external noise
using a shielded or twisted wire.
Terminal SE is a common terminal for the open collector output terminal (RUN, FU). The contact input circuit is isolated from
the internal control circuit by photocoupler.
(4) Wiring instructions
1)It is recommended to use the wires of 0.3mm
2
to 0.75mm
2
gauge for connection to the control circuit terminals.
2)The maximum wiring length should be 30m (200m for terminal FM).
3)Do not short terminals PC and SD. Inverter may be damaged.
4)Use two or more parallel micro-signal contacts or twin contacts to prevent
contact faults when using contact inputs since the control circuit input signals
are micro-currents.
5)Use shielded or twisted wires for connection to the control circuit terminals and
run them away from the main and power circuits (including the 200V relay
sequence circuit).
6)Do not apply a voltage to the contact input terminals (e.g. STF) of the control
circuit.
7)Always apply a voltage to the fault output terminals (A, B, C) via a relay coil, lamp, etc.
3) Insert the wire into a socket.
When using a single wire or a stranded wire without a blade terminal, push an
open/close button all the way down with a flathead screw driver, and insert the wire.
NOTE
When using a stranded wire without a blade 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 to damage of
inverter or injury.
Pull the wire with pushing the open/close button all the
way down firmly with a flathead screwdriver.

NOTE
Pulling out the terminal block forcefully without pushing
the open/close button all the way down may damage the
terminal block.
Use a small flathead screwdriver (Tip thickness: 0.4mm/
tip width: 2.5mm).
If a flathead screwdriver with a narrow tip is used,
terminal block may be damaged.

Place the flathead screwdriver vertical to the open/close
button. In case the blade tip slips, it may cause to dam-
age of inverter or injury.
