Safety information
2.1
Main operating information
Noxious 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 reflec‐
tor unit is opened during operation. Exposure of the unprotected skin and eyes to radia‐
tion is dangerous to health.
b
Disconnect the power supply of the device before opening the device.
b
Wear suitable protective goggles and protective gloves when work on the open
device with the power supply connected is performed.
Noxious gas
WARNING
Risk to health through contact with toxic gases
The modules and equipment contain enclosed, potentially dangerous gases that can
escape should a defect or leak occur. Should a leak occur, the concentrations within
the enclosed equipment can rise up to 40 ppm.
■
NO: 2 ml maximum total volume
b
Only open the device when good ventilation is available, especially when a leak of
one of the device components is suspected.
DANGER
Hazard by gas escaping when the SR-unit is swiveled out
Overpressure in the gas duct can cause hot and/or noxious gases to escape when the
SR-unit is swiveled out.
b
Swivel the SR-unit out only when you have taken suitable safety measures.
b
Set the lever on the purge air fixture to the “Close” position".
Electrical safety through power isolating switches properly installed
WARNING
Endangerment of electrical safety during installation and maintenance work when the
power supply is not switched off
b
Before starting the work on the device, ensure the power supply can be switched
off using a power isolating switch/circuit breaker in accordance with DIN EN
61010.
b
Make sure the power isolating switch is easily accessible.
b
An additional disconnecting device is mandatory when the power isolating switch
cannot be accessed or only with difficulty after installation of the device connec‐
tion.
b
The power supply may only be activated again after the end of the work or for test
purposes by personnel carrying out the work under consideration of valid safety
regulations.
