Connect the DC reactor for suppressing harmonics to terminals +1
and +2.
When driving the Inverter with DC power, input the DC power to
terminals +1 and –.
(Terminal +1 is a positive terminal.) (Terminal +1 is a positive terminal )
Be sure to ground the terminal under the following conditions.
3G3JV-A2j: Ground at a resistance of 100 Ω or less.
3G3JV-ABj: Ground at a resistance of 100 Ω or less.
3G3JV-A4j: Ground at a resistance of 10 Ω or less, and connect
to the power supply's neutral phase to conform to EC Directives.

Note NPN is the default setting
for these terminals. Wire
th them by providing a b idi
common ground. No
external power supply is external power supply is
required. To provide an
external power supply and
wire the terminals through
a common positive line,
however, set the SW7 to
PNP and make sure that PNP and make sure that
the power supply is at
24 V DC ±10%.
