Setting:
1 Open parameter r12 and stop the
regulation
2 Select electric connection based on
the drawings on page 1
3 Open parameter o61 and set the elec-
tric connection number in it
4 Now select one of the preset settings
from the table
5 Open parameter o62 and set the
number for the array of presettings.
The few selected settings will now be
transferred to the menu.
6 Regulation is now started (r12 was set
to 1 in point 5)
7 Go through the survey of factory set-
tings. Make any necessary changes in
the respective parameters.
8 For network. Set the address in o03
and then transmit it to the gateway/
system unit with setting o04.
