4.2 Mounting, drives sizes J to M
• The REFUdrive 500 drives, sizes J to M are module and are designed
for installation in cabinets.
• The drive units have mechanical grid dimensions of 22.5 mm. Several
drive units can be mounted next to one another without any intermedi-
ate space when using mounting rails with threaded holes with the di-
mension grid (also refer to the mounting example).
• The drives must be mounted vertically onto a flat surface.
• A minimum clearance of 100 mm above and below the drives must be
maintained to ensure an unrestricted cooling airflow.
• When mounted in cabinets, the cooling airflow requirement of the in-
stalled drives must be calculated and the cabinet ventilation appropri-
ately dimensioned.
• The mounting bolts are specified in the drilling templates of the dimen-
sion drawings.
