 Wire removal
Pull the wire while pushing the open/close button all the way down firmly with a flathead screwdriver.
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.

Driver
• Place the flathead screwdriver vertical to the open/close button. In case the blade tip slips, it may cause an inverter damage
or injury.
 Common terminals of the control circuit (SD, PC, 5, SE)
• Terminals SD (sink logic), PC (source logic), 5, and SE are common terminals (0 V) for I/O signals. (All common terminals
are isolated from each other.) Do not earth (ground) these terminals. Avoid connecting terminal SD (sink logic) with
terminal 5, terminal PC (source logic) with terminal 5, and terminal SE with terminal 5.
• In the sink logic, terminal SD is a common terminal for the contact input terminals (STF (DI0), STR (DI1), RH, RM, RL,
MRS, and RES) and the pulse train output terminal (FM
circuit by photocoupler.
• In the source logic, terminal PC is a common terminal for the contact input terminals (STF (DI0), STR (DI1), RH, RM, RL,
MRS, and RES). The open collector circuit is isolated from the internal control circuit by photocoupler.
• Terminal 5 is a common terminal for the frequency setting terminal (2 or 4) and the analog output terminals (AM
be protected from external noise using a shielded or twisted cable.
• Terminal SE is a common terminal for the open collector output terminals (RUN and FU). The contact input circuit is
isolated from the internal control circuit by photocoupler.
*1 Terminal FM is provided in the FM-type standard model inverter.
*2 Terminal AM is provided in the AM-type standard model inverter.
 Signal inputs by contactless switches
The contact input terminals of the inverter (STF (DI0), STR (DI1), RH, RM, RL, MRS, and RES) can be controlled using a
transistor instead of a contact switch as follows.
