Safety Guidelines for Using BAKS Cable Routes

1. BAKS cable routes and their components are intended for routing and supporting power, telecom, pneumatic, water, and other cables. To ensure safe use, observe the following rules:
Cable trays must be properly designed and selected by qualified personnel experienced in electrical installations and, where applicable, licensed to design, paying special attention to product purpose, dimensions, allowable load, material, corrosive environment, etc.
Improper design or selection may pose a health and safety risk, cause malfunction, or damage the product.
2. Cable routes must be properly installed and grounded by qualified personnel experienced in electrical work. Improper installation or grounding may pose a health and safety risk, cause malfunction, or damage the product.
3. Cable routes must be inspected, serviced, and cleaned at intervals not exceeding 12 months by qualified personnel.
Failure to perform regular maintenance may pose a health and safety risk, cause malfunction, or damage the product.
4. Cable routes must not be used as walkways, climbing paths, or for hanging/transporting objects. Such use may cause collapse, endanger health and safety, and/or damage the product.
5. Cable routes must not be used for storing, installing, or suspending additional items or installations contrary to their intended purpose, e.g., during construction, installation, service, or renovation works. Such use and/or additional loading of the cable route may result in collapse, pose a risk to health and life, and/or lead to damage.
