Inspecting the Equipment
Ifanyequipmentreceivedhasbeendamagedduringshipment,keeptheshipping
cartonsandpackingmaterialsforthecarrierorplaceofpurchaseandfileaclaimfor
shippingdamage.Ifyoudiscoverdamageafteracceptance,fileaclaimfor
concealeddamage.

Tofileaclaimforshippingdamageorconcealeddamage:1)Filewiththecarrier
within15daysofreceiptoftheequipment;2)Sendacopyofthedamageclaim
within15daystoyourservicerepresentative.

NOTE Check the battery recharge date on the shipping carton label. If the date has expired and the
batteries were never recharged, do not use the UPS. Contact your service representative.
Unpacking the Cabinet
