The PM is designed to be mounted in a number of orientations. To maintain sealing
to IP54, certain rules must be observed for the different mounting scenarios, as
follows :

0RXQWLQJ5XOHV

1.

The vent hole area must be protected against direct splashing.

2.

The mounting arrangement must prevent water accumulation under the vent
hole area.
