1.4 Positioning
The cabinet is structurally designed to handle lifting from the base.
Power terminals, auxiliary terminals blocks and power switches are accessed from the front and top.
Removable panels on the top are secured to the chassis by screws. The door can be opened to give
access to the power connections bars, auxiliary terminal blocks and power isolators. The front door
can be opened 180° for easier service and more flexibility in installation.
1.4.1 Moving the Cabinets
The route to be travelled between the point of arrival and the unit’s installation location must be
planned to make sure that all passages are wide enough for the unit and that floors are capable of
supporting its weight (for instance, check that doorways, lifts, ramps, etc., are adequate and that
there are no impassable corners or changes in the level of corridors).
Ensure that the cabinet weight is within the designated surface weight loading (kg/cm
2
) of any
handling equipment. See Table 2 for weight details.
Ensure that any lifting equipment used to move the battery equipment has sufficient lifting capacity.
Battery system equipment can be handled by a forklift or similar equipment.
Because the weight distribution in the cabinet is not symmetrical, use extreme care during handling
and transporting.
When moving the unit by forklift, care must be taken to protect the panels. Do not exceed a 15° tilt
with the forklift. Bottom structure will support the unit only if the forks are completely beneath the
unit.
Handling the unit with straps is not authorized.
The cabinet with top terminal batteries ships with extra bolts installed on the interior doors. Once the
cabinet is in the final position, these bolts can be removed. See Figure 1

WARNING
Risk of heavy unit falling over. Can cause equipment damage, injury and death.
Exercise extreme care when handling battery cabinets. The battery system cabinets weigh
from 3760 to 8990 lb. (1706 to 4078kg).
Locate center of gravity symbols and determine unit weight before handling each
cabinet. Test lift and balance the cabinets before transporting. Maintain minimum tilt from
vertical at all times.
Slots at the base of the cabinets are intended for forklift use. Base slots will support the unit
only if the forks are completely beneath the unit.
