(with a cable diameter of less than 11 mm, the strain-relief force is reduced from
100 N to a maximum of 80 N)
With cable diameters greater than 21 mm, the M32 cable gland must be replaced
by an M32 cable gland with a larger clamping area – item number: 42,0407,0780
– strain-relief device M32 x 1.5 KB 18-25.
Cable diameter
of the DC cable
Cable diameter for the strain-relief device: max. 9 mm.
.Cable diameter for the connection to the push-in terminal: max. 6 mm
IMPORTANT!
For double-insulated cables with a cable diameter over 6 mm, the external insu-
lation layer must be removed to connect to the push-in terminal.

NOTE!
The national regulations of the grid
operator or other factors may require
a residual current circuit breaker in
the AC connection lead.
For this situation, a type A residual
current circuit breaker is generally ad-
equate. Nevertheless, false alarms can
be triggered for the type A residual
current circuit breaker in individual
cases and depending on local condi-
tions. For this reason, in accordance
with national legislation, Fronius re-
commends that a residual current cir-
cuit breaker with a tripping current of
at least 100 mA suitable for frequency
converters be used.
IMPORTANT!
As a maximum, the inverter can be
used with an automatic circuit breaker
32 A.
