Liebert 49" Battery Cabinet

Liebert 33" Battery Cabinet

The same model battery 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 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 Services for recommended precautions.

! CAUTION

Any battery system should be installed by properly trained and qualified personnel.

When installing an external battery cabinet that is NOT a Liebert NX battery cabinet, the customer must provide overcurrent protection. See Table 8 for sizing of protection devices.

NOTE

When using an external battery supply that is not provided by Liebert, refer to the battery manufacturer’s installation manual for battery installation and maintenance instructions, available on the manufacturer’s Web site.

NOTE

When replacing batteries, Liebert recommends that the all batteries in external cabinets be the same type. See Table 11 for a list of batteries that are approved for use with this product.
