Mechanical integration

4. Mechanical integration
This section describes the mechanical aspects of the IMD. See IMD 100 Datasheet for physical
dimensions.

4.1 Integrating the IMD in a cabinet

4.1.1 Environmental requirements

The IMD must be mounted in a closed cabinet where the requirements for ingress protection of
components do not exceed IP 20.
The IMD heatsink is mounted through a hole in the cabinet and requirements for ingress protection
outside the cabinet do not exceed IP 55 (IP 54 for IMD 122 B).
When designing the pitch system, pay attention to IMD location in the hub, to avoid debris entering the
heatsink (1). Take the hub rotation into account, so that loose objects are not funnelled into the
heatsink.

4.1.2 Temperature considerations

This section describes the considerations concerning temperature and ventilation when designing the
cabinet in which the IMD is placed, and the location of the cabinet.
4.1.2.1 Personal safety considerations
The heat sink (both in and out) can get hot depending on the ambient temperature and the activity of
pitching the blade. If there is a risk of people touching the back of the IMD (the heat sink outside the
cabinet) it is recommended to implement measures to protect personnel such as physical guards,
information, or any other means.
