6.7.2 Assembling the DC connectors
Assemble the DC connectors as described below. Be sure to
observe the correct polarity. The DC connectors are marked with
the symbols "+" and " − ".
Cable requirements:
The cable must be of type PV1-F, UL-ZKLA or USE2 and comply
with the following properties:
External diameter: 5-8mm
⚫
Conductor cross-section: 2.5-6mm²
⚫
Qty single wires: minimum 7
⚫
Nominal voltage:minimum 1000V
1. DC cable requirements as follows:
Danger to life due to high voltages on DC conductors
When exposed to sunlight, the PV array generates
dangerous DC voltage which is present in the DC
conductors. Touching the DC conductors can lead to lethal
electric shocks.
• Cover the PV modules.
• Do not touch the DC conductors.
