Special safety precautions are required for procedures involving handling, installation and maintenance of the UPS system. Only properly trained and qualified personnel wearing appropriate personal protective equipment should be involved in installing the Liebert NXL Battery system or preparing the system for installation.

WARNING Risk of heavy unit falling over. Can cause equipment damage, injury or death. Exercise extreme care when handling battery cabinets to avoid equipment damage or injury to personnel. The battery system cabinets weigh from 3760 to 5750 lb. (1706 to 2608kg). Locate center of gravity symbols and determine unit weight before handling each cabinet.
This following section describes the requirements that must be taken into account when planning the positioning and cabling of the Liebert NXL battery equipment. This chapter is a guide to general procedures and practices that should be observed by the installing engineer.
Mechanical Installation Positioning The cabinet is structurally designed to handle lifting from the base. Access to the power terminals, auxiliary terminals blocks and power switches is from the front and top. Removable panels on the top are secured to the chassis by screws. The door can be opened to give access to the power connections bars, auxiliary terminal blocks and power isolators.
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.
NSTALLATION Safety Special care should be taken when working with the batteries associated with the Liebert NXL Bat- tery 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 equip- ment in an isolated area, accessible only to properly trained and qualified maintenance personnel.

2.4.3 Attached/Detached System For battery cabinets that are connecting to a Liebert NXL UPS, Liebert NXL MBD cabinet or Liebert NXL Junction cabinet (see Figures 2 through 6), cables will run from the positive and negative bus- bars of the adjacent battery cabinet to the positive and negative DC connections of UPS, MBD or Junction cabinet.
Table 15 for current ratings and recommended cable sizes. Control Connection Each Liebert NXL Battery Cabinet and Liebert NXL Module Battery Disconnect (MBD) contains a Battery Interface Board (BIB). See 3.0 - Installation Drawings. All cabinets in a system must have their Battery Interface boards connected in series.

External Battery Room Temperature Sensor—Optional For systems that do not use Liebert NXL battery cabinets, but have an MBD connected to a battery string, an optional temperature sensor can be installed to monitor the ambient room temperature. This sensor is connected to the BIB in the MBD cabinet (see Figure 11). This sensor will allow the Liebert NXL UPS to perform temperature compensation charging.
