For details about the main and control circuit terminals, refer to Chapter 2, Section 2.3.5 and Section
2.3.6 (Table 2.9), respectively.
8.4.2 Running the inverter with keypad
Ground-fault circuit interrupter
(Note 1) When connecting an optional DCR, remove the jumper bar from the terminals [P1] and [P (+)].
(Note 2) Install a recommended MCCB or RCD/GFCI (with overcurrent protection) in the primary circuit of the
inverter to protect wiring. At this time, ensure that the circuit breaker capacity is equivalent to or lower than
the recommended capacity.
(Note 3) Install an MC for each inverter to separate the inverter from the power supply, apart from the MCCB or
RCD/GFCI, when necessary.
Connect a surge killer in parallel when installing a coil such as the MC or solenoid near the inverter.
(Note 4) THR function can be used by assigning code "9" (external alarm) to any of the terminals [X1] to [X5], [FWD]
and [REV] (function code; E01 to E05, E98, or E99).
