Power Supply Line - Steca Grid 20000 Installationsanleitung

Also observe the following requirements specified by the local network operator:

Pertinent technical and special rules and regulations

The installation approval must be submitted.
Before connecting the inverer to the AC network, isolate the power connec-
tion, verify that the system is de-energized, and protect the circuit breaker
against reactivation.
CAUTION

Check the line voltage, which may not exceed 265 V (phase against neutral conduc-
tor). If the line voltage is higher than 265 V, contact your local network operator.

Apply the power cable to the supplied connector as illustrated, connect the power cable
to the inverter and fasten the connector.
Note: When using wire end ferrules with isolating collar, make sure you do not
introduce the insulation of the wire end ferrule into the clamping area of the
terminal.

4.8 Power Supply Line

Select the cross-section of the power supply line such that line losses are as low as possible. How-
ever, observe the following points:
 Due to the construction, the recommended feed line for all cross-sections is a fine-strand
line.
 The cable fitting of the standard connector housing supplied allows a 5 x 6 mm² cable to be
connected. The maximum outside diameter of the power supply line may be 18 mm
(e.g. Lapptherm 145.5 x 6 mm²).
 Optionally, you can also order a larger connector housing allowing connection of a
5 x 10 mm² power supply line.
The table below shows the maximum line lengths in relation to the conductor cross-section
with a voltage drop of <= 1%.
