1.4 Positioning
The cabinet is structurally designed to handle lifting from the base.
Access to the power terminals, auxiliary terminals blocks and power switches is 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 at 180° for better service and more flexibility in installations.
1.4.1 Moving the Cabinets
The route to be travelled between the point of arrival and the unit’s position 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 han-
dling equipment. See Table 4 for weight details.
Ensure any lifting equipment used in moving the battery equipment has sufficient lifting capacity.
Battery system equipment can be handled by means of a forklift or similar equipment.
Because the weight distribution in the cabinet is uneven, 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 degrees
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 battery ships with extra bolts installed on the interior doors. Once the cabinet is in the final posi-
tion, these bolts can be removed. See Figure 1
!
WARNING
Risk of heavy unit falling over. Can cause equipment damage, injury or death.
Exercise extreme care when handling battery cabinets to avoid equipment damage or injury
to personnel. The battery system cabinets weigh from 3760 to 5750 lb. (1706 to 2608).
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.
