Placement of the Drive in the Installation
6.7.6
Before mounting the drive, prepare the mounting location with appropriate fasteners so the drive can be positioned safely. Make sure
that there is enough space to handle the drive safely during installation.
Lower screws or bolts can be mounted before installation. Position the drive on the lower bolts, and mount the upper screws or bolts.
The broken torque for screw holes on the mounting surface must be no less than 1.5 Nm (13.3 in-lb).
Cooling
6.7.7
For proper cooling for the drives, ensure that there is sufficient clearance above and below the drive. See
required cooling clearances.
For all installations, the temperature of the installation site must be kept within the specified operating temperature range by ventilation
or cooling. The quality of the cooling air must comply with the environmental conditions as defined in the technical specifications (dust,
airborne particles, chemical substances).
