CU-EMA+
DANGER
Electric voltage
Risk of electric shock
a) Always disconnect the unit from the mains before work-
ing on it. After shutting off the power, allow a discharge
time of at least 5 seconds.
b) Secure the device from accidental restarting.
c) The unit may only be opened by trained, competent per-
sonnel.
d) Ensure the correct voltages supply.
DANGER
Potential equalisation
Connect the system's potential equalisation to the potential
equalisation on site. Stray electric currents may not flow
through this connection.
WARNING
Hazardous electrical voltage
The device must be installed by trained staff only.
WARNING
Electric voltage
Insulation test will damage the device
Do not test the electric strength if the entire unit is under
high voltage!
CAUTION
Wrong mains voltage
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.
CAUTION
Supply cable
The power adapter must be suitable for the maximum power
used by the device.
It must be heat-resistant and must not come into contact
with hot surfaces. The power supply must meet IEC 60227 or
IEC 60245. Or be approved by another recognised testing
body.
NOTICE
Please note:
The structure and quality of the electrical installation can
have a considerable impact on the reliability and perform-
ance of the devices. We therefore strongly recommend the
personnel responsible for the electrical installation familiar-
ise themselves with the included circuit diagrams and in-
structions before planning the installation. Please observe the
local laws. The device must be connected by a trained profes-
sional. Please also note the operation instructions for the in-
dividual devices.

4.4 Gas Connections

Please refer to the assembly plan in chapter Dimensions (mm)
for the number and positions of gas connections
The heated sample gas line must have a downward slant to-
ward the gas inlet.
After connecting the sample gas line it must be braced and se-
cured with the clamp. Longer sample gas lines may require
additional clamps along the device path.
