Tab. 2.
Recommended cross sections for power cables.
The recommended cross sections for power cables take
into account the following conditions:
Ambient temperature: 30°C.
AC losses less than 3%, DC losses less than 1%. AC
power cable lengths less than 50m, DC power cable
lengths less than 30m.
The voltages indicated in the table are based on three-
phase 380 V systems (phase-to-phase voltage).
If the usual load is not linear, the cross sections of the
neutral lines must be multiplied by a factor of 1.5 to 1.7.

Tab. 4.
Recommended circuit breakers.
The use of circuit breakers with built-in residual current
detection (RCD) devices is not recommended.
5.3.3.4. Connection of the power cables.
Connect the power cables according to the following instructions:
1.
Make sure that the rectifier and bypass input cables have no
voltage when connecting them. Mark the switches so that
they are not improperly activated.
2.
Open the back door of the cabinet and remove the plastic
cover. The battery, earth and input and output terminals are
shown in Fig. 38.
3.
Connect the earth wire to the PE terminal.
4.
Connect the AC input wires to the input terminals and the
AC output wires to the output terminals.
5.
Connect the battery wires to the battery terminals.
6.
Make sure that there are no errors and replace all protec-
tive covers.
