+1 Connection ter1 and +2:
DC reactor connection terminals
+1 and –:
DC power supply input terminals
Connect the DC reactor for suppressing harmonics to terminals
+1 and +2.
When driving the Inverter with DC power, input the DC power to
ter1 and –.
(Te1 is a positive terminal.)

Ground terminal Be sure to ground the terminal under the following conditions.
CIMR-J7AZ2
_
: Ground at a resistance of 100
Ω
or less.
CIMR-J7AZB
_
: Ground at a resistance of 100
Ω
or less.
CIMR-J7AZ4
_
: Ground at a resistance of 10
Ω
or less, and connect
to the power supply’s neutral phase to conform to EC Directives.
Note Be sure to connect the ground terminal directly to the
motor frame ground.
