Terminal Description
* DC power supply input terminal is not available on CE/UL standards.
Type Terminal Name Function (Signal Level)
Main Circuit
R/L1,
S/L2,
T/L3
AC power supply input
Use main circuit power input (for single-phase inverter,
R/L1, S/L2).
Even thought T/L3 is available, do not use the terminal
for other purposes such as relay terminal.

Inverter output Inverter output
+2, +1 DC reactor connection
When connecting optional DC reactor, remove the main
circuit short-circuit bar between +2 and +1.
+1, (–) DC power supply input
DC power supply input (+1: positive, –: negative)
