NOTICE
Using the correct combination of line diameter and insulat-
ing sleeve significantly affects the IP level of the entire sys-
tem.
4.6 Connecting the Gas Line
The sample gas line must be carefully and properly connected
using a suitable fitting.
This table provides an overview of the sample gas probe con-
nections:

Varies by version.
Please note the following items when connecting the sample
gas line (NPT 1/4") on heated probes to prevent thermal
bridges:
• Choose the shortest possible screw connection.
• Shorten the connection pipe for the sample gas line as
much as possible.
Long sample gas lines may require support clamps along the
way to the analysis system!
WARNING
Gas emanation
Sample gas can be harmful to the health!
Check the lines for leaks.

4.7 Connecting the calibrating gas line (optional)
Connecting the calibrating gas line requires a Ø6 mm or Ø1/4"
pipe fitting.
If the calibrating gas connection was ordered with check
valve, a Ø6 mm or Ø1/4" pipe can be connected directly to the
check valve.
4.8 Electrical connections
The operator must install an external separator for the device
which is clearly assigned to this device.
This separator
pipe clamp
insulation band
worm drive hose clip
heated sample gas line
The RCD (tripping current 30 mA) must shut off the load
within the required amount of time. It must be suitable for
the maximum load.
An additional, or integrated in the separator, overcurrent
device is required. All feeders except the ELCB must have over-
current devices, e.g. circuit breakers or fuses. This should be
next to each other, have the same rating, and not be integ-
rated in the neutral wire of multi-phase equipment.
For the applicable separator data, please note the values spe-
cified under chapter Technical Data.
The probe itself has self-regulating heating elements and can
therefore be connected to a 100 V – 230 VAC power supply.
Probe
The probe comes with a connection housing which contains

the terminal strip for connecting the mains supply for the
heater and a potential-free temperature switch. Connect per
DN65/PN6/DN3"-150
Connection Diagram [} 000].
G3/4
NPT 1/4
All connection lines must be fed into the system through the
cable glands. Include strain relief for the connection cables.
Tube Ø6 mm
The supply line cross-sections must be suitable for the rated
Tube Ø1/4
current and meet local regulations.
Please refer to the Technical Drawing for the clamping ranges.
Hazardous electrical voltage
The device must be installed by trained staff only.
Supply cable
The power adapter must be suitable for the maximum power
input of the device. It must be heat-resistant and must not
come into contact with hot surfaces. The power adapter must
meet IEC60227 or IEC60245. Or be approved by another recog-
nised testing body.
Wrong mains voltage
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.
• must be located near the device,
• must be easy for the operator to reach,
• must comply with IEC 60947-1 and IEC 60947-3,
• must separate all live conductors and the status output,
and
• must not be attached to the power feed.
