If mounting washers are used, they must be 30mm or greater in diameter for
stability.

If the PM is mounted with its connectors upward, the connector should be
shielded from water ingress and the cabling restrained such that water may
not run down the cables into the connector systems.

The selected position and orientation should give the module maximum
mechanical and environmental protection. Avoid positions in which the
module or its wiring can be knocked or physically damaged or which are
exposed to splashing or other forms of abuse.
The length of high current cabling should be minimised. A position close to
the batteries and motors is favoured.
An orientation and position in which the fins are vertical and airflow through
the fins is unimpeded is preferred.
An orientation in which the PM Status LED is visible may be helpful.
Mounting the PM on a metal surface may assist heat conduction and give
better performance.
When all wiring is completed, it must be securely fastened to the wheelchair
frame to ensure that in normal conditions there is no strain to the connectors.
Once the position has been selected
fix the unit securely using two M5
socket cap screws with suitable
locking washers. Dimensions for hole
centres are as shown.
To fulfill ISO requirements, the left and right motor connections must be
short enough so that they can not be swapped by the wheelchair user.
