Inverter internal circuits
+SU
Input
DC power input terminal for operating the
control circuit. Connect a control power backup
device (optional) between +SU and CC.
Voltage:24Vdc±10%
Use a power supply
with a current rating
of 1.05A or more.
(In case of not install
options, current rating
is 300mA )
FLA
FLB
FLC
Output
Relay contact output. Contact rating
Used to detect the activation of the inverter's
protective function. Contact across FLA-FLC is
closed and FLB-FLC is opened during
protection function operation.
