5. The positive connection cables of the PV modules must be
fitted with the positive DC connectors. The negative
connection cables of the PV modules must be provided with
the negative DC connectors.
5.5.2 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:
1. External diameter: 5-8mm
2. Conductor cross-section: 2.5-6mm²
3. Qty single wires: minimum 7
4. Nominal voltage: minimum 1100V
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.
