3.9 Rack Anchoring Stage
Install the rack frame on a flat, level surface.

To attach the rack and perform the related works
CAUTION

Use a proper transportation method considering the weight of the rack frame.

Ensure that the safety of the working place is maintained.

When using a forklift, lift the rack frame from the front.

When a forklift cannot be used, use a mechanical lift or move it by hand with three or more
people.

Use lock washers to prevent bolts from loosening.

Use an inclinometer or carpenter’s level to ensure that the rack frame is plumb.
NOTICE

Failure to anchor the rack frame on a flat and level surface may distort the rack frame after
installing the racks side-by-side.

Frame distortion may make the rack doors difficult or impossible to open.
NOTICE

In seismically active areas, the front panel and the rear panel of the rack frame must be
installed.
In order to anchor the racks in all four points, racks are recommended to be placed according to the workable
distances listed in the table below. In seismically active areas, all four anchor points of the rack must be installed.
To reduce the product footprint, the racks can be installed side-by-side and rear-to-rear against a wall or next to
another rack. In this case, only two anchor points on the front side of each rack can be installed. Proper cooling and
ventilation of the installed area is recommended for racks installed with no side and rear clearance. Front side of
the rack must be cleared for installation, maintenance, service access, and ventilation and cooling.
Clearance from the top of the rack frame is not required and the top of the rack frame can be covered to prevent
any foreign objects from falling into the battery rack frame.
