Please Note: For your protection, this product manual should be read and
thoroughly understood before unpacking, installing, using, or servicing the
described equipment.
UNIPOWER, LLC presents all equipment to the delivering carrier securely packed and
ready for transport. Upon acceptance of the equipment from us, the delivering carrier
assumes responsibility for its safe delivery to you. Once you receive the equipment, it is
your responsibility to document any damage to the equipment that was sustained during
transport to you and to file your claim with the carrier promptly and accurately.
PACKAGE INSPECTION
Before unpacking the shipment, examine the shipping container for any visible damage: punctures, dents, and any
other signs of possible internal damage.
Describe any damage or shortage on the receiving documents and have the carrier’s representative sign his/her
full name.
If the receiving freight bill notes that a Tip-N-Tell is attached to your freight, locate the indicator and note the
color of the arrow. If the Tip-N-Tell arrow has turned even partially blue, this means the freight has been tipped in
transport. Make sure the carrier notes this on your receipt before you sign for the freight.
EQUIPMENT INSPECTION
Promptly upon receipt of shipment, open the container and inspect the contents for damage; see the unpacking
section that follows. If it is necessary to move or otherwise handle the shipment, refer to the Handling section for
instructions and warnings.
Unpack the shipment carefully to avoid scratching or otherwise marring the exterior finish. Be careful not to
discard any included equipment, parts, or manuals. If damage is detected, call the delivering carrier to determine
appropriate action. The carrier may require an inspection.

damages may void warranty service for any physical damages later reported for repair.
UNPACKING
A charger is shipped attached to a wood skid. This facilitates handling with a lift truck by inserting the forks
under the bottom of the skid. A smaller unit is covered by a carton and banded to a skid. A larger unit is bolted
to a skid and covered by a shipping carton that is banded to the skid.
Export packaging consists of a crate, a moisture-resistant cover for the charger, and a drying agent. The charger is
bolted to the crate.
To unpack:
CAUTION
Do not stand in front of steel bands since they may
whip out when cut.
ATTENTION
Ne pas se tenir devant les bandes d'acier, lorsque
coupées.
1. Cut the bands and remove carton from the skid.
2. Either remove the unit from the carton or unbolt the unit from the skid.
3. Check the shipping carton, before discarding, for the packing slip and other material, which may be
contained in it.
4. Carefully inspect the charger for shipping damage (i.e. loosened connections or mountings, dislodged
circuit boards). If damage is detected, notify UNIPOWER, LLC; contact information is provided in
Section 1.5 Product Support.
STORAGE
If the charger is not to be used immediately, store it (fully packed, if possible) in a clean, dry location protected
from physical damage, condensation, and overhead drip.
