Warning

The device must never be opened by the user at any place other than the lamp shaft. Life-threatening
electric currents are used or generated in the device; in particular, the device must never be used with
the housing open. The device must never be used when there are audibly loose parts inside the device.
The device must never be operated in moist environment (e.g. during precipitation) nor must
the control device or the operating pendant be submerged in water – there is a risk to life due
to electric currents!
Before start-up, the device must be acclimatized according to the ambient temperature.
This is valid in particular for cooled devices, wherein condensate accumulation during warm-up
can lead to destruction and damage due to electric spark over.
Never operate the device under conditions which do not comply with the operating conditions
or storage conditions described in the instructions manual!
The device must be checked annually by the manufacturer or an authorized third party for compliance
with the electrical safety instructions obligatory at the usage site and conformance with the as-deli-
vered condition of the device. The device must not be connected to the electric supply mains or other-
wise operated after the ascertainment of a defect or any deviation from the as-delivered condition.
This is valid, in particular, if the device has tumbled or fallen down or was exposed to a liquid.
The device must never be operated in operating environments which are vulnerable to explosion
or fire risk. The device is not equipped with safety devices or acceptance for operation in environ-
ments vulnerable to explosion or fire risk. An impermissible employment in environments suscep-
tible to explosion or fire leads unavoidably to a device-induced life-threatening explosion and to a fire
in the plant. The operator is obliged to check the plant for substances vulnerable to explosion or fire
before every new start-up of the device.
:: Warning
Never allow the device to be operated without supervision.
For safety reasons, it is necessary to switch-off the machine during pauses.
Never operate the device in radioactively contaminated environment!
Never expose the probe to ionizing radiation of any type!
The device must be transported exclusively in the transport case conceived for it by the
manufacturer. The device and the corresponding accessories must be packed in the transport
case only according to the instructions at hand.
For increasing your own safety against electric shocks with risk of injury or loss of life, the device
must always be connected and operated via a residual current circuit breaker system or an isolating
transformer. This can in any case be a compulsory condition depending upon the operating environ-
ment. For this, consult your responsible safety in-charge or the accident protection measures in
force in your respective country.
The use of too long power extension cords is life-threatening and forbidden (max. 25 m in case of
a supply line made of copper 3 x 1.5 mm2). Hereby, a life-threatening loss of the protective function
of the upstream safety element is possible. At the same time, voltage differences of the earth po-
tential as compared to the displaced reference point of electric output (bridged by a too long exten-
sion cord) could cause dangerous electric currents on contact with the device housing or
impermissibly high equalizing currents at the probe. In case of uncertainties, consult your on-site
electrical expert.
