Control circuit specifications
3) Insert the wire into a socket.
When using a stranded wire without a bar terminal, push a open/close button all the way down with a flathead screw
driver, and insert the wire.
Note
When using a stranded wire without a bar 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.
Wire removal
Pull the wire with pushing the open/close button all the way down firmly with a flathead screwdriver.
Note
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 damage of
inverter or injury.
(3) Control circuit common terminals (PC, 5, SE)
Terminals PC, 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 terminal PC and 5 and the terminal SE and 5.
Terminal PC is a common terminal for the contact input terminals (STF, STR, RH, RM, RL). The open collector circuit is
isolated from the internal control circuit by photocoupler
Terminal 5 is a common terminal for the frequency setting signals (terminals 2 or 4) and analog signal output (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 terminal (RUN). The contact input circuit is isolated from the
internal control circuit by photocoupler
