REMARKS

•To ensure safety, connect the power input to the inverter via a magnetic contactor and earth leakage circuit breaker or no-fuse breaker, and use the magnetic contactor to switch power on-off.

•The output is three-phase 200V.

1.1.2Explanation of main circuit terminals

(1) Main circuit

Terminal	Terminal Name	Description
Symbol
R/L1, S/L2,	AC power input	Connect to the commercial power supply.
T/L3 (*1)
U, V, W	Inverter output	Connect a three-phase squirrel-cage motor.
PR (*2)		Do not use PR terminal.
	Brake unit	Connect the brake unit (BU), power regeneration
P/+, N/−		common converter (FR-CV) or high power factor
	connection	converter (FR-HC). (The N/- terminal is not provided for
		the FR-S520E-0.1K to 0.75K-NA.)
	Power factor	Remove the jumper across terminals P - P1 and connect
		the optional power factor improving DC reactor (FR-
P/+, P1	improving DC
	reactor	BEL(-H)).
		(The single-phase 100V power input model cannot be
	connection
		connected.)
	Ground	For grounding the inverter chassis. Must be grounded.

*1. When using single-phase power input, terminals are R/L1 and S/L2.

*2. The PR terminal is provided for the FR-S520E-0.4K to 3.7K-NA.
