3.5.1 Wall-mounting
The drive can be mounted in vertical or horizontal position on the wall or any other relatively even
mounting plane or machine frame and fixed with the screws recommended in Table 8.
Recommended screw or bolt size for MM4 is M5, for MM5 M6 and MM6 is M8.
3.5.2 Motor-mounting
The drive can also be mounted on a motor (on top or on any side of the motor). The drive is equipped
with a cooling system independent of the motor. Motor-mounting requires special adapting com-
ponents. Contact your local VACON
®
distributor for additional information.
3.5.3 Segregated modules
In order to ease replacements in case of failure, the power and the control sub-systems are en-
closed in two segregated parts, connected together through pluggable terminals:
• Power-head: heat-sink enclosing all power electronics
• Terminal-box: block containing unit control and power terminals
Firstly, the terminal-box has to be fixed and the cabling has to be done. Secondly, the power-head
has to be plugged and fixed to the terminal-box with dedicated screws (see Table 9). In order to pre-
serve the specified IP protection class, the recommended fastening torque is 2-3 Nm.
