Waterproof cable glands are most suitable for use in environments where water and debris may pass through the cable opening. These cable fittings form a tight seal that can act as a barrier against water and debris and prevent unnecessary damage to the electronic equipment connected to the cable.
When used with cable accessories, these cable glands perform two key functions: connect the cable to the lighting accessory and seal the cable opening to prevent water and particles from entering. When the lamp is to be used outdoors, waterproof cable accessories must be used. Using the wrong cable gland will destroy the IP protection level of the accessory and may cause water and particles to enter the accessory.
When installing the lamp outdoors, the cable gland must be tightened. After installation, the cable glands need to be checked regularly. If these show signs of deterioration, they should be replaced immediately.
If you use single core or multiple cables, avoid using single cable glands. This will only cause water to enter. If you must use more than one cable when installing the luminaire outdoors, choose a junction box. This will eliminate the possibility of water and dust seeping through the cable opening.
