Control circuit terminal
 Wiring precautions
• It is recommended to use a cable of 0.3 to 0.75 mm
• The wiring length should be 30 m (200 m for terminal FM) at the maximum.
• 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.
• To suppress EMI, use shielded or twisted cables for the control circuit terminals and run them away from the main and
power circuits (including the 200 V relay sequence circuit). For the cables connected to the control circuit terminals,
connect their shields to the common terminal of the connected control circuit terminal. When connecting an external
power supply to terminal PC, however, connect the shield of the power supply cable to the negative side of the external power supply. Do not directly earth
(ground) the shield to the enclosure, etc.
• Always apply a voltage to the fault output terminals (A1, B1, C1, A2, B2, C2) via a relay coil, lamp, etc.
• Do not connect any terminal SD on the inverter and the 0 V terminal of the external power supply (when the sink logic is selected).
 Wiring method
• Crimp terminals commercially available (as of April 2019)

Description
The setting dial of the Mitsubishi Electric inverters. Turn the setting dial to change
the setting of frequency or parameter, etc.
Press the setting dial to perform the following operations:
• To display a set frequency in the monitoring mode (The monitor item shown on the
display can be changed by using Pr.992.)
• To display the present setting during calibration
• To display a fault history number in the fault history mode
Switches the operation panel to a different mode.
The easy setting of the inverter operation mode is enabled by pressing this key
simultaneously with [PU/EXT] key.
Every key on the operation panel becomes inoperable by holding this key for 2
seconds. The key inoperable function is invalid when Pr.161="0 (initial setting)".
(Refer to the FR-A800 Instruction Manual (Detailed).)
Confirms each selection.
When this key is pressed during inverter operation, the monitor item changes.
(The monitor item can be changed according to the settings of Pr.52, Pr.774 to
Pr.776.)
Goes back to the previous display.
Holding this key for a longer time changes the display back to the monitor mode.
Switches between the PU operation mode, the PUJOG operation mode, and the
External operation mode.
The easy setting of the inverter operation mode is enabled by pressing this key
simultaneously with [MODE] key.
Also cancels the PU stop warning.
