5.4 AC Connection
5.4.1 Conditions for the AC connection
Cable Requirements
The grid connection is made using 5 conductors (L1, L2, L3, N, and PE). We recommend
the following requirements for stranded copper conductor.

A
External diameter
12…21 mm
B
Conductor cross-section
2.5…6 mm
2
C
Stripping length of the insulated conductors
Approx. 9 mm
D
Stripping length of the AC cable’s outer sheath
Approx.72 mm
The PE insulated conductor must be 2 mm longer than the L and N conductors
Larger cross-sections should be used for longer leads.
Cable Design
The conductor cross-section should be dimensioned to avoid power loss in cables
exceeding 1% of rated output power.
The maximum cable lengths relative to the conductor cross-section as follows:

Before performing the electrical connection, ensure that the AC circuit-breaker is switched
off and cannot be reactivated.
