N O T I C E
Use only earthed sockets for the connection of this device to the power supply.
If it is not clear whether the sockets are earthed, have this checked by a qualified
electrician.
In addition to supplying power, the power plug also serves to isolate the device quickly
from the mains where necessary.
The entire measurement system has two power plugs (measurement device and control
unit). 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
On removal of the power plug (fixed installation of mains supply lead), a suitable bipolar
circuit breaker must be installed!
N O T I C E
Pull out the power plug before opening the device.
