Setting:
1 Open parameter r12 and stop the
regulation
2 Select electric connection based on
the drawings on page 2
3 Open parameter o61 and set the elec-
tric connection number in it
4 Open parameter r12 and start the
regulation
5 Go through the survey of factory set-
tings. Make any necessary changes in
the respective parameters.
