Electrical Connections

Installation and connecting power and signal cables are subject to qualified
personnel only taking into account all applicable standards and legislative
requirements! Especially the standard EN 60079-14 „Electrical Installations
in Hazardous Areas" and all related standards have to be observed.
Failure to follow may cause warranty invalidation, property damage and/or
personal injury or death!
Installation of these instruments is subject to qualified personnel only,
familiar with the resulting potential risks! Instruments providing screw
terminals for electrical connections may require working near live part!
Analyzers described in this manual do not provide a power switch!
A power switch or circuit breaker (complying with IEC 60947-1/-3) has to be
provided in the building installation. This switch has to be installed near
by analyzer, must be easily operator accessible and has to be assigned as
disconnector for the analyzer.
Disconnect instruments with screw terminals from power when working at
power terminals (pull power plug or operate power switch/ circuit breaker
in building installation)!
The analyzers provide a protective earth terminal. To prevent electrical
shock hazards the instruments must be connected to a protective earth.
Therefore the instruments must be connected to power by using a three
wire power cable with earth conductor!
Any interruption of the earth connector inside or outside the instrument
or disconnecting the earth terminal may cause potential electrical shock
hazzard!
The analyzers do not provide a power switch and are operable when connec-
ted to power.
