Boththeconnectionand commissioning of the unit must only be carried
out by skilled personnel. In case of a wrong connection, the unit may be
destroyed-no warranty claims can beaccepted!
Safety regulations
Makeitaruletoalwaysobserve the following points to exclude any risk whatsoever for the operator.
a) In case of any obvious damage and/or functional problems disconnect unit immediately
b) Prior to opening it, disconnect unit and supply voltage source. Make sure that all parts of the unit are protected against direct
touching when mounting the unit and setting its connections.
c) Please always adhere to the standard safety regulations for electric devices, power systems and light-current installations,
and make sure that your national safety regulations (e.g. VDE 0100) are observed.
d) If unit is to be connected to other devices (e.g. via serial interface) the circuitry has to be designed most carefully. Internal
connection in third party units may result in not-permissible voltages.
Skilled personnel
These are persons who are familiar with the installation, mounting, commissioning and the operation of the product and have
acquired a qualification for their job:
nTraining or instructions or qualification to switch on/off, isolate, ground and apply markings to circuits and devices/systems
in accordance with the latest state of the art standards of safety technology.
nTraining or instructions regarding the proper care and use of suitable safety equipment in accordance with the latest state of
the art standards of safety technology.
nFirst aid training.
Warning: When operating electric devices parts of these devices will, as a matter of course, be live.
Unless the warnings are observed severe damage to life and limb or to property may be the
result. Make sure that only skilled personnel is working with this device. Trouble-free
operation of this device can only be guaranteed if it is properly transported and stored.
Carefull installation, mounting, operation and maintenance are vital factors for the safe
operation of this device.
