InstallatIon and maIntenance
Chassis-mounted variable speed drive
mecHanIcal InstallatIon
To ensure correct operation of the drive, it is essential to
respect dimensions below.
(a): distance between the roof of the cabinet and an obstacle
(e.g. wall, etc). several cabinets can be assembled together
(ensure that the air is extracted correctly).
2.4.3 - Temperature
do not place the drive above a heat source or another drive.
the delta between the internal temperature of the cabinet and
the ambient temperature outside the cabinet must not be
greater than 5°c.
For example, for an ambient temperature of 40°c outside
the cabinet, the internal temperature in the cabinet should
be no more than 45°c. If this is not the case with the
PoWeRdRIVe md2cs’s own ventilation, add ventilation
on the cabinet roof (e.g. for a cabinet 600x600, add further
ventilation of at least 225 m3/hr).
the optional braking resistor must be located outside the
cabinet, but as close as possible.
