Mating and Disconnecting

• Always de-energize the PV system before mating and disconnecting the connectors.
• Never disconnect the connectors under load.
• Never connect male or female parts of Stäubli connectors with connectors from other manufacturers.
• Never mate contaminated connectors.

Do NOT Modify or Repair Component

• Do not modify the component after assembly.
• Replace defective components.

Technical Data

Attention:

When connecting the connectors, ensure that the rated data (current carrying capacity and rated voltage) are dependent on the mating connectors used. Refer to the assembly instructions for the specific connectors being used.

Tools and Installation

Tools/Assembly Materials Required

For integration into a PV cable harness system:

• PV-MS-PLS Assembly and unlocking tool (1 set = 2 pcs., Order No. 32.6058)
• Open-end spanner set PV-MS (Order No. 32.6024)

Note: Refer to Operating Instructions MA270 available at www.staubli.com/electrical.

Notes on Installation

General Notes on Installation

• Unmated connectors must be protected from environmental impact (moisture, dirt, dust, etc.) with sealing caps (socket order no. 32.0716; plug order no. 32.0717).
• Do not mate contaminated connectors.
• Connectors must not come into contact with any chemicals.

Cable Routing

Cable management must allow a minimum of 20 mm of cable exiting directly from the cable seal without bending or stress. Refer to cable manufacturers' specifications for minimum bending radius. (Visual representation: A cable exiting a seal with a minimum clearance of 20mm indicated).

Contaminated/Damaged Connectors

• Do not allow connectors to be contaminated by the environment (e.g., soil, water, insects, dust).
• Do not allow the connector surface to be contaminated (e.g., stickers, paint, heat shrink tubing).
• Do not allow the connector to be directly on the roofing surface.
• Do not allow the connector to be at the lowest point of cabling where water can collect.
• Do not allow the connector to be in standing water.
• Do not allow cable ties to be mounted directly on the connector body.

Mechanical Stress

• Check that the connectors are not subjected to permanent mechanical tensile load or vibration.
• Connectors shall not be under strain from cable management.
