NGA 2000 MLT Hardware
TECHNICAL DESCRIPTION
MLT2 (FIELD HOUSING)
Connection of mains and interface signals are to be established via internal
screw terminal blocks. This requires working inside an opened analyzer,
near by potentially live components!
Installation of this analyzer is allowed by qualified personnel only, familiar
with the potential risks of working near live components!
The model MLT 2 (field housing) does not provide a mains switch. A mains
switch or circuit breaker must be provided in the building installation. This
switch has to be installed near by the analyzer, must be easily operator
accessible and has to be designated as disconnector for the analyzer.
Cables for external data processing must be double insulated for mains
voltage. If not available, signal cables inside the analyzer must be installed
with a distance of at least 5 mm to mains cables. Distance has to be ensured
permanently, e.g. by using cable ties!
The analyzer variation MLT 2 intended to be wall mounted and/or outdoor
installed weigh up to 35 kg, depending on included options!
Use two person and/or suitable tools for transportation and lifting these
instruments!
Take care to use anchors and bolts specified to be used for the weight of
the units!
Take care the wall or stand the unit is intended to be installed at is solid
and stable to hold the units!
MLT 2 analyzers provide earth connection terminals. To minimize risk of
electric shock the enclosure must be connected to earth! Therefore
connecting the analyzer is allowed only by using a 3 pole mains cable
providing a separate earthing conductor.
Any interruption of the earthing conductor inside or outside the analyzer as
well as loosening the earthing connection may cause serious injury! Intended
interruption of earthing connections is not permissible!
