convection heating. Make sure that it is installed so that the ambient temperature
is within the specified temperature range, e.g. by avoiding obstruction of the
airflow around the unit. Also check chapter EN 45545-2 mounting notes.
Before mounting, using or removing this unit:
Prevent access to hazardous voltage by disconnecting the unit from all power supply.
WARNING
Do not open connected unit. Hazardous voltage may occur within this unit when
