For example, a battery cabinet contains 16 pcs of 12V battery, and all of them connect in series, the nominal voltage of this battery cabinet is 192Vdc. It would match the UPS which should connect 16 pcs of battery, battery voltage 192Vdc or charging voltage 218.4.
Weak current engineering refers to the design, installation and maintenance of a series of low-voltage and low-current systems inside buildings.
Wiring is the circulatory system of your PLC Cabinet, connecting all the vital components. Poor wiring can lead to inefficiencies, malfunctions, or even hazards. Therefore, understanding the fundamentals is key. Choosing the right type of wire is essential for your PLC system’s safe and efficient operation.
Several factors need to be considered when designing a battery room floor. For VRLA batteries the simplest of protection is normally acceptable but rooms housing vented battery types need to be impermeable for battery acid or alkaline for nickel cadmium types.
If you’re constrained by floor space or need to situate your PLC in a specific, elevated location, wall-mounted cabinets are an excellent choice. These are often used in smaller setups or as secondary units in more extensive systems. They’re convenient but typically offer less room for expansion than other types.
Battery acid and lead compounds and the risk of explosion due to the build up of explosive gasses should be discussed. The hazards with nickel cadmium batteries, which contain highly corrosive potassium hydroxide and give off hydrogen, should be discussed. No persons should be allowed to enter a battery room without the correct clothing.
