IMPORTANT
INFORMATION
See the "Technical Data" chapter
for the dimensioning of the re-
quired AC line circuit breaker and
the cable cross-section and cable
type to be used. Ch. 9.1
If using an AC cable with an outer
diameter of 15-23 mm, the reducing
ring provided should be used.
Both single-wire (type NYY-J) and
multi-wire (type NYM-J) cables
without core end sleeves can be
used with the AC terminal.
When using cables with fine wires
(type H05../H07RN-F), core end
sleeves should be used. Ensure
that there is a contact surface of
18 mm.
IMPORTANT
INFORMATION
Existing cables and their routing
within the inverter must not be
changed. This can otherwise result
in malfunctions in the inverter.
