1.4 Description of I/O Terminal Specifications

1.4.1 Main circuit

Symbol	Terminal Name	Description
R, S, T *	AC power input	Connect to the commercial power supply.
<L1, L2, L3>
U, V, W	Inverter output	Connect a three-phase squirrel-cage motor.
N<->	DC voltage	DC voltage common terminal. Not isolated from the
	common	power supply and inverter output.
	Power factor	Disconnect the jumper from terminals P<+>-P1 and
P<+>, P1	improving DC	connect the optional power factor improving DC reactor
	reactor connection	(FR-BEL). (The single-phase 100V power input model
		cannot be connected.)
	Earth (Ground)	For grounding the inverter chassis. Must be earthed.

*R, S <L1, N> terminals for single-phase power input.

CAUTION

<>Terminal names in parentheses are those of the EC version.
