Fastening the cabinet to the floor and wall or roof
￭ General rules
• The drive must be installed in an upright vertical position.
• Leave 250 mm (9.85”) of free space above the cabinet for maintenance, and to allow
pressure relief operation.
• The cabinet can be installed with its back against a wall (a), or back-to-back with another
unit (b).
•
Leave some space (w) at the side where the cabinet outmost hinges are to allow the
doors to open sufficiently. The doors must open 120° to allow supply or inverter module
replacement.
Note 1: Any height adjustment must be done before fastening the units or shipping splits
together. Height adjustment can be done by using metal shims between the cabinet bottom
and floor.
Note 2: If the cabinet is delivered with lifting bars, remove them. Lifting eyes need not be
removed unless the holes are used for fastening the cabinet. Plug any unused holes using
the existing bolts and sealing rings included. Tighten to 70 N·m (52 lbf·ft).
