►
UV radiation
DANGER
Damage to eyes and skin by UV radiation
The in-situ gas measuring device GM32 emits UV radiation when the SR-unit or reflector
unit is opened during operation. Exposure of the unprotected skin and eyes to radiation
is dangerous to health.
Disconnect the power supply of the device before opening the device.
►
Wear suitable protective goggles and protective gloves when work on the open
►
device with the power supply connected is performed.
Risk of explosion
DANGER
Risk of explosion through residual voltages and hot surfaces in the device
When the device is switched off, residual voltages and hot surfaces represent an
increased risk of explosion when the device is open.
Wait 20 minutes after switching off the main power supply before opening the
►
enclosure.
DANGER
Hazard for health through contact with inert protective gas
Inert protective gas can emerge uncontrolled when the device is opened directly after
switching off. Direct contact with inert protective gas is a high health risk, including risk
of suffocation.
Interrupt the inert gas feed before opening the device so that only the volume of
►
inert gas in the device can escape.
Ensure good ventilation and air exchange.
►
Never open the device when the room is too small.
