Smart-Sample-Tube

4.5 Electrical connections

The device is equipped with a CEE-7/7 Schuko plug and may
only be connected to the corresponding sockets. Never modify
the plug in any way. Never use adapter plugs with earthed
electrical devices.
The operator must ensure the separator of the prevailing
building installation is working properly. This must cut out
the load within the prescribed amount of time, cut all live con-
ductors of the supply connection and be suitable for the
highest load conditions. Furthermore, the electric circuit being
used must be equipped with a circuit breaker (line circuit
breaker) (max. release current 16 A).
In the case of mobile applications where the safeguards of
sockets are unknown, a PRCD (Portable Residual Current oper-
ated Device) is also recommended.
WARNING
Dangerous voltage due to equipment damage
Never use devices with damaged connection line - doing so
increases the risk of electric shock.
CAUTION
Wrong mains voltage
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.
CAUTION
Equipment damage
Supply cable damage
a) Never misuse the cable to carry or hang the device or to
disconnect the plug from the socket.
b) Route the cable carefully to prevent it from coming into
contact with hot surfaces and sharp edges.
c) Do not kink the connection cable, always loosely wrap in
a large loop.
5 Operation and Control
NOTICE
The device must not be operated beyond its specifications.
CAUTION
Hot surface
Risk of burns
Depending on the operating parameters, surface temperat-
ures of exposed parts may reach up to 200 °C (392 °F) during
operation.
Depending on the installation conditions on site, these areas
may require a warning sign.
Allow the unit to cool down before performing maintenance.

5.1 Before Start-Up

Before starting the device, verify:
• the supply cable is not dam-
aged and routed carefully (no
hot surfaces or sharp edges).
• Precautions have been taken.
• the earth is proper and func-
tional.
• the gas inlet and outlet on the
gas probe are not blocked (e.g.
due to factory dust plug).
• ambient parameters are met.
• Probe parts are resistant to
media to be conveyed and in
the surrounding area.
• the heated sample gas line to
transport gas is installed cor-
rectly.
• the plug in the assembly open-
ing is properly installed in the
housing.
• the calibrating gas line is cor-
rectly installed or, if necessary,
sealed with a plug.
• the performance specifications
in the type plate are met.
• the monitoring equipment is
connected and set as specified.
• the properly is properly in-
stalled at the sampling point.
• measures have been taken to
ensure the connection
between the connection piece
and sample tube is tight.
Suitable measures must be taken when installing the probe at
the sampling point, as hand-held operation is not permissible
due to the high surface temperatures. We recommend hand-
ing it with a mounting bracket and chain (see figures; sold
separately).
