2.4 Installation - Electrical
EXPLOSION AND ELECTRICAL SHOCK HAZARD
Failure to follow the instructions provided below may cause warranty
invalidation, property damage and personal injury or death!
Installation and connecting power and signal cables are subject to qualied
personnel only taking into account all applicable standards and legislative
requirements!
Take care of the relevant installation standards, as there are (but not limited
to) e.g. EN 60079-14 (Europe), National Electrical Code (NEC-NFPA 70; USA),
Canadian Electrical Code (CEC; Canada), IEC 60079-14 (International) and
others, and all corresponding standards.
Installation of these instruments is subject to qualied personnel only,
familiar with the resulting potential risks! Instruments providing screw
terminals for electrical connections may require working near live part!
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 (operate power switch / circuit breaker in building
installation)!
Connecting and disconnecting ameproof X-STREAM analyzers is permitted
only, if the instrument and all associated power & signal lines are de-
energized!
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.
