Surge Arresters – Type 2 for PV Systems

Connecting Cable for DEHNcube
• PV connecting cables for easily connecting DEHNcube
YPV SCI 1000 … to the inverter
• Suitable for outdoor use
• 6 mm² for minimum voltage drop
• Cable can be shortened individually to the optimum length
• Unnecessary cable lengths are avoided, thus better protective
effect due to lower transmission loss

Prewired connecting cables for easily connecting the incoming string lines to
DEHNcube and the inverter.

AL DCU Y PV L3X1000: For connecting strings to DEHNcube and the inverter

To ensure easy and quick connection of the DEHNcube YPV SCI 1000 1M
and DEHNcube YPV SCI 1000 2M surge arresters, DEHN offers the pre-as-
sembled connecting cables AL DCU Y PV L3X1000 which can be used to
conveniently connect the string lines to DEHNcube and the inverter.
The AL DCU Y PV connecting cable allows you to connect a string to the
input of an inverter to protect it from surges. This cable features three ends DCU
for connection to the inverter, DEHNcube and the string line. The designa-
tion Y symbolises the three cable ends. DC

possible. The connecting cables have a cross-section of 6 mm² which Application: One string per d.c. input (MPP tracker) of the inverter.
means that transmission loss is reduced to a minimum. Due to their de-
sign, they are suitable for outdoor use in PV systems.
The figure shows an example of how to connect an inverter with
DEHNcube and two string lines (DC+/DC-). In this case, two AL DCU Y PV
L3X1000 connecting cables are required.
The applications shown here can also be used for inverters with two MPP
inputs which are protected by DCU YPV SCI 1000 2M.
