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:
External diameter: 5 mm to 8 mm
Conductor cross-section: 2.5 mm² to 6 mm²
Number of conductors: at least 7
Nominal voltage: at least 600V
Proceed as follows to assemble each DC connector.
1.
Strip 12 mm off the cable insulation.
2.
Route the stripped cable all the way into the DC connector. Ensure that the
stripped cable and the DC connector have the same polarity.
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.
