Notes on Installation

General notes on installation

Sealing caps (socket order no. 32.0716; plug order no. 32.0717) are available to protect unmated connectors from environmental impact (moisture, dirt, dust, etc.).

• 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 specification for minimum bending radius. [Diagram description: A visual representation shows a cable exiting the connector seal. A minimum straight length of 20mm is indicated. A sharp bend or bending too close to the connector is marked with a red 'X' symbol, indicating it is prohibited.]

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 that the connector is directly on the roofing surface.
• Do not allow that the connector is at the lowest point of cabling where water can collect.
• Do not allow that the connector is in standing water.
• Do not allow that 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.
