WARNING

Risk of heavy units tipping over while being moved. Can cause property damage, injury and death.

The Liebert eXM TXC and battery cabinets must be properly prepared and secured for lifting.

Improper lifting may cause the cabinets to fall, causing equipment damage, personal injury and death.

Emerson recommends lifting the units with one of the following methods:

• Installing four eyebolts in the factory-fabricated holes, one at each corner of the unit, attaching cables or similar strapping to the eyebolts and lifting with a suitable mechanism.

• Placing suitable straps on the Liebert eXM TXC. The straps must go under the unit to be lifted.
