Wiring Of Control Circuit - Mitsubishi Electric FR-E700 Instruction Manual

2.3.3

Wiring of control circuit

(1) Standard control circuit terminal layout
Terminal screw size
M3: (Terminal A, B, C)
M2: (Other than the above)
(2) Wiring method
1) Strip off the sheath of the wire of the control circuit to wire.
Strip off the sheath about the size below. If the length of the sheath peeled is too long, a short circuit may occur among
neighboring wires. If the length is too short, wires might come off.

2) Loosen the terminal screw and insert the wire into the terminal.
3) Tighten the screw to the specified torque.
Undertightening can cause wire disconnection or malfunction. Overtightening can cause a short circuit or malfunction due
to damage to the screw or unit.
Tightening torque: 0.5N·m to 0.6N·m (terminal A, B, C)
0.22N·m to 0.25N·m (other than the above)
* Screwdriver: Small flathead screwdriver (Tip thickness: 0.4mm/tip width: 2.5mm)
(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, MRS, RES). 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 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

Wire the stripped wire after twisting it to prevent it from
becoming loose. In addition, do not solder it.
Use a bar terminal as necessary.
