Replacing the desiccant on the transmitter
DANGER!
Danger of injuries on the UV light source caused by electric shocks, UV radiation
and high temperatures.
When replacing the desiccant, careless handling can lead to electric shocks, eye injuries
caused by UV radiation and burns due to temperatures in excess of 80 °C. It is thus essen-
tial to observe the following safety measures when removing the UV light source:
The service voltage must be interrupted before opening the housing.
The instrument must not be operated when the housing is removed under any circum-
stances.
Before opening, wait until the instrument has cooled down to a manageable tempera-
