Kabel DELOCK 90971 zonnepaneelaccessoire, 3 m, 4 mm² aderdoorsnede, DL4 stekker–bus, 1000 V DC, rood/zwart

DELOCK 90971 is a 3 m solar panel accessory cable designed for DC power transmission in photovoltaic systems. The cable features two 4 mm² cores (red/black) with DL4 male and female connectors and is rated for up to 1000 V DC. With a nominal cable diameter of approximately 5 mm and IP67 protection on the connectors, this cable is suitable for outdoor installation between panels, junction boxes and inverters where DL4-compatible connections are required.

Advantages

The DL4 plugs and sockets use a snap-in locking mechanism that reduces the risk of accidental disconnection while allowing release with the appropriate tool. IP67 protection provides resistance against dust and temporary immersion in water, and the operating temperature range from -40 °C to 90 °C supports reliable performance in a wide variety of climates. The cable is compatible with common solar connector systems such as MC4, TS4 and QC4, facilitating integration in existing installations.

How to use

Ensure that connectors on the system are DL4-compatible before installation. Route the cable between the intended connection points, avoiding sharp edges and areas of high mechanical stress. Insert the DL4 male plug into the DL4 female socket until the snap-in lock engages; verify the secure connection visually and mechanically. Use the appropriate tool specified for DL4 connectors when disengaging the snap-in lock. Observe correct polarity by connecting red to positive and black to negative terminals.

Recommendations

For safe installation, de-energize circuits before connecting or disconnecting the cable. Use strain relief and appropriate cable glands where the cable enters enclosures. Regularly inspect connectors for signs of wear, contamination or damage and replace the cable if insulation or connector integrity is compromised. Match cable length and cross section to system current requirements and follow national electrical codes and manufacturer guidelines when integrating into a PV system.
