Note:
If the power is turned
on when the input
terminals 1 to 5 are
kept on, all the data
stored in the inverter
is initialized.
Therefore, never turn
the power on in such
a state.

Terminal RS can use only contact a (normally open). It cannot use contact b (normally closed).
(NOTE 1)
CAUTION
Alarm connection may contain hazardous live voltage even when inverter is disconnected.
In case of removing flont cover for maintenance or inspection, confirm that incoming power
for alarm connection is surely disconnected.
