Installation
Mounting
When mounting the PDM take into account that the PDM may get very hot
during operation.
Ensure the PDM is mounted in a well ventilated area and not against a hot
surface. For case dimensions see Mounting Dimensions.
The internal temperature is highly dependent on ambient temperature and
also on the total load current
—a higher current will cause a higher
temperature.
Tip: The internal temperature can be checked in PDM Manager (see
Operation) or transmitted via CAN to be logged. Allow for sufficient time
for the temperature to stabilise. This may take 30 minutes or more.
If the internal temperature of the PDM exceeds the specified maximum values
(see Specifications), cooling may be achieved by one or more of the following:

relocating the PDM to a cooler mounting position

increasing air circulation around the PDM case

ducting cool air over the PDM case

fitting a heatsink to the back surface of the PDM case
