ELECTRICAL SHOCK HAZARD
Only qualied personnel, observing all applicable technical and legal
requirements, may install these devices and connect power and signal
cables.
Failure to comply may render the guarantee void and cause exposure to
risk of damage, injury or death.
The devices may only be installed by personnel who are aware of the
possible risks. Working on units with screw-type terminals for electrical
connections may require exposure to energized components.
Wall-mounted X-STREAM analyzers are not tted with power switches and
are operational as soon as they are connected to a power supply.
For these analyzers a switch or circuit breaker (IEC 60947-1/-3) must be
installed on the premises. The switch or breaker must be located near the
analyzer, easily accessible and labelled as a power supply cut-off for the
analyzer.
Units with screw-type terminals must be de-energized by unplugging it or
operating the separate cut-off switch or circuit breaker when working on
the power connections.
To avoid the risk of electrocution, all units must be earthed. For this reason,
the power cable with a protective earth wire must be used.
Any break in the earth wire inside or outside the unit may cause exposure
to the risk of electrocution and is therefore prohibited.
