ATTENTION:
The buzzer built-in voltage may amount to 24 V DC. The contact is in an open state of rest
and is separated galvanically. (That is, there is no electronic contact between the MediaClave and external
power supply. This is realised by relays or opto-electronic parts.) The forced opening cover only operates
with a battery and a maximum 24 V DC voltage.
ATTENTION:
Never open the vessel lid when operating the instrument.
ATTENTION:
The forced opening of the safety cover is not galvanically separated and must only be op-
erated with a battery.
