Assembling the DC Connectors
Qualified person
For connection to the inverter, all PV module connection cables must be fitted with the DC connectors provided. Assemble the DC connectors as described in the following (refer to the manufacturer manual for further information on assembling the DC connectors). Be sure to observe the correct polarity.
DANGER
Danger to life due to electric shock when live components or DC cables are touched
When exposed to light, the PV modules generate high DC voltage which is present in the DC cables. Touching live DC cables results in death or lethal injuries due to electric shock.
- Do not touch non-insulated parts or cables.
- Disconnect the product from voltage sources and ensure it cannot be reconnected before working on the device.
- Do not disconnect the DC connectors under load.
- Wear suitable personal protective equipment for all work on the product.
Additionally required material (not included in the scope of delivery):
Stripping tool
Crimping tool suitable for crimping the cold-formed contact ferrules (observe manufacturer information).
Tool for tightening the swivel nut (observe manufacturer information).
Where applicable, tool for checking whether the conductors with contact ferrules plug far enough into the DC connector (observe manufacturer information).
Procedure:
- Strip off the conductor insulation by 7 mm ±0.5 mm (0.28 in ±0.02 in).
- Thread the cold-formed contact ferrule onto the stripped conductor and crimp using a crimping tool suitable for the cold-formed contact ferrule.
- Guide the conductor with the cold-formed contact ferrule into the connector until the cold-formed contact ferrule snaps audibly into place in the DC connector.
- Ensure that the conductor with the cold-formed contact ferrule is plugged far enough into the DC connector and has snapped into place.
- Tighten the DC connector swivel nut (torque: 3.5 Nm to 4 Nm (31 in-lb to 35 in-lb)).
