exceed 6 mm. No other holes need to be drilled for mounting.
Details regarding the mounting depth and mounting cut-out are provided on
Page 8-2.
Degree of protection
The IP65 degree of protection for the front panel can only be ensured when the
seal on the front plate of the MP270 is fitted correctly.

The unit must be brought to room temperature before it is commissioned. If
condensation forms, do not switch the unit on until it absolutely dry.
To prevent the MP270 from overheating during operation,
– the angle of inclination from vertical installation may not exceed a maximum
of 35 .
– do not expose the operating unit to direct sunlight
– ensure that the ventilation slits in the housing remain free after installation.
When the cabinet is opened, certain parts of the system that may conduct
hazardous voltage are exposed.
