1. During the installation and maintenance of the waterproof junction box body, the sealing ring at the lid of the plastic junction box must be compressed to prevent water entering or affecting the explosion-proof performance.
2. Check the waterproof junction box regularly. Check whether the bolts of the waterproof junction box are loose. If so, please ask a professional to repair them.
3. For waterproof junction boxes with cable glands, the sealing gaskets at the cable glands should be inspected frequently. It is better to order spare parts from the manufacturer. Once the product is aged or damaged, it could be replaced in time.
