1 The open end spanner is used to disconnect the DC cables from the
DC inputs.
Typically yellow/green copper cable with minimum wire size 6 mm
has to be used. Always consider local regulation regarding the cable
requirements.
Depending on which connectors you want to use (RS485, dry con-
tacts, digital inputs), you need the appropriate cables with wire size
1 mm .

magnetic screw driver, so that the screws cannot accidentally fall into
the inverter.
1 A grounding fuse with 1 A is needed. The fuse holder is delivered with
the inverter.
- Check local regulations whether you have to attach special safety
labels to the inverter.
