Grid connection
The grid connection is made using 3 conductors (L1, N, PE).
There is an appropriate cable fi tting on the underside of the
housing for inserting the leads.
We recommend the following conductor cross-sections for
cable lengths up to 20 m:
–
Powador 2002 1.5 mm²
–
Powador 3002 2.5 mm²
–
Powador 4202 4.0 mm²
–
Powador 5002 4.0 mm²
–
Powador 6002 6.0 mm²
Larger cross-sections should be used for longer leads.
In accordance with VDE 0100 part 430, "Protection of cables
and lines against overcurrent", NYM leads with fi xed wiring
should be secured as follows:
Installation type B2 (multi-conductor lead in pipe or duct,
either on or in walls or fl ush-mounted) at an ambient tempera-
ture of +25 °C.
–
1.5 mm² 16 A
–
2.5 mm² 20 A
–
4.0 mm² 25 A
–
6.0 mm² 35 A
NEOZED gL safety fuses should be used.

Be sure to use cables with a suffi ciently large cross-sec-
tion to avoid excessive line impedance between the build-
ing's distribution box and the respective Powador unit.
When the line impedance is high (i.e. long AC-side leads),
the voltage at the line terminals of the inverter will
increase as power is being fed in to the grid. The inverter
measures this voltage. If the voltage at the grid terminals
exceeds the line overvoltage limit, the inverter will switch
off due to line overvoltage. This condition must be taken
into consideration when wiring the AC and dimensioning
the AC lead.
Risk of electric shock at live connections.
Check that the power lead is voltage-free before
inserting it into the unit.

Guide the lead, which has been stripped of its jacket and
insulation, through the cable fi tting.
Connect the lead, which has been stripped of its jacket
and insulation, as shown on the label on the right side of
the PCB terminal.
Check that the leads are properly connected.

Once again, ensure that all connected leads are fi rmly
connected.
Tighten the cable seal of the cable fi tting.
