Electrical dangers and fire hazard. Use only the supplied power cable
Only qualified experts may perform the tasks described in this section of the
manual, in compliance with all locally applicable safety regulations.
N O T I C E
Use only earthed sockets for the connection of this device to the power supply.
If you are not sure if the sockets are earthed, have this checked by a qualified
electrician.
The power plug serves in addition to the power supply to isolate the device
quickly from the mains where necessary.
The entire measurement system has two power plugs (measurement device
and refrigerator). During the disconnection from the mains it must be made sure
that the correct power plug is pulled (e.g. labeling of the sockets).
This is recommended for long-term disuse and can prevent potential dangers in
the event of a fault.
Therefore make sure that the sockets to which the device is connected are easy
to reach by each user at all times.
N O T I C E
As the refrigerator itself is not provided with a fuse, it may only be connected to a
