Page 11: Clearances
1.4.2 Clearances Liebert NXL has no ventilation grilles at either side or at the rear of the battery system equipment. Clearance around the front of the equipment should be sufficient to enable free passage of personnel with the doors fully opened. It is important to leave a distance of 24" (610mm) between the top of the cabinet and the ceiling of the room in which it is installed to permit adequate circulation of air coming out of the unit and for service access. -
Page 12: Battery Installation
NSTALLATION Safety Special care should be taken when working with the batteries associated with the Liebert NXL Battery System equipment. When all the cells are connected together, the battery terminal voltage will exceed 400V and is potentially lethal. A primary safety consideration is to install the battery equipment in an isolated area, accessible only to properly trained and qualified maintenance personnel. -
