3.4External Battery Cabinet Installation

3.4.1Matching Battery Cabinets

Two sizes of optional battery cabinets are available. Refer to Figures 13 and 14. The same model bat- tery cabinet may be installed in parallel in multiple cabinet strings for additional capacity. Battery run time depends on the cabinet model, the number of cabinets and the load on the UPS.

Handling—The battery cabinet has casters to facilitate movement over short distances. The bottoms of the battery cabinets are reinforced to permit movement by forklift over longer distances.

Inspection—Remove all panels and visually inspect the batteries, bus connections, and cabinet for any damage. Exercise caution; voltage is present within the battery cabinet even before installation. If there are signs of damage, do not proceed. Call Liebert Global Services at 1-800-542-2378.

Storage—The batteries can be stored for up to six months without appreciable deterioration. If plan- ning to store a battery cabinet for longer than six months or at temperatures higher than 77°F (25°C), contact Liebert Global Services for recommended precautions.

The following notes, in conjunction with the diagrams (Figure 13 through 12), illustrate the broad principles to be followed when fitting and connecting the majority of battery cabinet installations.

! CAUTION

Any battery system should be installed by qualified personnel.

When installing an external battery cabinet that is NOT a Liebert NX battery cabinet, the customer must provide overcurrent protection. See Table 10 for sizing of protection devices.

NOTE

When using an external battery supply that is not provided with the UPS, please make reference to the battery manufacturer’s installation manual for battery installation and maintenance instructions, available on the manufacturer’s Web site. When replacing batteries, Liebert recommends that the batteries in external cabinets be the same type used internally in the NX. See Table 11 for a list of batteries that are approved for use with this product.

3.4.2Connecting the Batteries

If the NX battery cabinets are installed on a raised floor, the battery power cables and circuit breaker control cables may be routed to the UPS cabinet via the floor of the cabinet (bottom entry).

If the NX battery cabinets are installed adjacent to one another on a solid floor, these cables may be passed between the cabinets through lifting slots in the lower sides of the cabinets.

Intertray connections must be made before the battery cabinet may be used.
