Safety Instructions

Importance of the Assembly Instructions

Not following the assembly and safety instructions could result in life-threatening injuries due to electric shock, electric arcs, fire, or failure of the system.

• Follow the entire assembly instructions.
• Use and install the product only according to this assembly instructions and the technical data.
• Safely store the assembly instructions and pass them on to subsequent users.

Requirements for Personnel

Only an electrician or electrically instructed person may assemble, install, and commission the system.

• An electrician is a person with appropriate professional training, knowledge, and experience to identify and avoid the dangers that may originate from electricity. An electrician is able to choose and use suitable personal protective equipment.
• An electrically instructed person is a person who is instructed or supervised by an electrician and can identify and avoid the dangers that may originate from electricity.

Intended Use

The connector electrically connects components within the DC circuits of a photovoltaic array. The product's primary function is the parallel electrical connection of two photovoltaic strings.

Prerequisites for Installation and Assembly

• NEVER use an obviously damaged product.
• ONLY tools and procedures approved by Stäubli shall be used.

Safe Assembly and Mounting

⚠️ Live parts can remain energized after isolation or disconnection.

• ONLY install the product when the photovoltaic array or string is de-energized.

Mating and Disconnecting

• ALWAYS de-energize the photovoltaic system before mating and disconnecting the connectors.
• NEVER disconnect the connectors under load.
• NEVER connect male or female parts of Stäubli connectors with connectors of other manufacturers.

Do NOT Modify NOR Repair Component

• Do NOT modify component after assembly.
• Replace defective components.

Technical Data

? Attention: When connecting the connectors, it must be ensured that the rated data (current carrying capacity and rated voltage) of the product are dependent on the mating connectors used. Observe the information in the assembly instructions for the connectors used.

Tools/Assembly Materials Required

For integration into a PV cable harness system:

? Note: Operating instructions MA270, available at www.staubli.com/electrical.

Installation Procedure

⚠️ Important - ELECTRIC SHOCK HAZARD!

Do not disconnect the product under load nor connect it in an electrical circuit that is under load.

Step: Using the appropriate disconnect tool, separate the mated connector.

Diagram Description: Two diagrams (ill. 4-5) show the process of separating a mated connector using a disconnect tool.

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 that exits directly from the cable seal without bending or stress. Refer to cable manufacturers' specifications for minimum bending radius.

Diagram Description: A diagram shows a cable exiting a connector seal with a minimum length of 20 mm indicated. A symbol suggests the importance of bending radius.

Contaminated/Damaged Connectors

• Do not allow connectors to be contaminated by the environment (e.g., soil, water, insects, dust).
• Do not allow the connector to be contaminated on its surface (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 a permanent mechanical tensile load or vibration.
• Connectors shall not be under strain from cable management.
