Storage advice: Be ready for further service!
It is crucial to instruct the operator in dealing with the operational states of their unit. Because it is the operator that is responsible for the proper operation of the installation. A thorough instruction early-on can prevent the need for quite a few service calls later. For instance, the end customer needs to know how to reactivate his unit from standby mode.
And this instruction needs to be documented. In the case of lead battery systems, data such as each cell’s level of charge at the point of start-up has to be recorded.
Protection against overvoltage
Just like any other electrical equipment, storage units have to be protected from overvoltage. The relevant fuses are usually included. To meet the insurers guidelines fitting a combined lightning and surge arrester is recommended, even though lightning or surge protection is not mandatory for smaller residential buildings.
The arrester protects the buildings installations and thus also the storage unit. In public or commercial buildings, lightning protection is mandatory, and other rules and requirements also apply to the protection of electrical systems from overvoltage. (HS)
