The installation of a Compact-Power™ battery requires attention concerning mechanical and electrical safety, ventilation and cooling, inspection and control opportunities. In the planning phase an intensive dialog of the prospective user/customer with our Technical Sales department or our local Sales organization is highly desirable. Furthermore local standards, building codes, code of practice etc. should be consulted so to satisfy local laws and regulations. One of the most recent standards for the operation of stationary battery UPS plants is the European Standard EN 50091:1:1993.
