• This converter has got a block with two switches
with two positions each (Fig. A1, item 1):
• Switch 1 allows to change the « OPERATION »
mode [switch 1->OFF] to « SERVICE » mode
[switch 1->ON] and vice versa. The « OPERA-
TION » position allows the selected mode to run
and hinders the access to parameters input (nor-
mal operating). The « SERVICE » position is used
to enter the parameters of the different opera-
tions.
• Switch 2 is for activating or deactivating the
« Access lock », see chapter 8.5.3.
• The switch 3 is not used.
• The switch 4 is not used.
