❏ Cables entering the analyzer housing should be kept as short as possible inside the
enclosure.
❏ The cable glands are suitable to fix cables with outer diameters of 7 to 12 mm. Special
adaptors are available for fixing other or multiple cables in one gland.
❏ Mains terminals are designed to connect wires up to a cross section of up to 2,5 mm².
❏ To ensure electromagnetic compatibility it is recommended to use shielded signal cables
only!
Take into account the installation instructions for cable glands (page 5-19)!
ELECTRICAL SHOCK HAZARD!
Installation and connecting mains and signal cables are subject to qualified
personnel only taking into account all applicable standards and legislative
requirements!
Failure to follow may cause warranty invalidation, property damage and/or
personal injury or death! Mains and signal cables need to be connected to
internal srew terminals requiring to work at open housing near life parts!
Installation of this instrument is subject to qualified personnel only, familiar
with the resulting potential risks!
MLT 2 gas analyzers do not provide a mains switch! A mains switch or
circuit breaker 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.
The analyzer provides a protective earth terminal. To prevent electrical shock
hazards the instrument must be connected to a protective earth. Therefore
the instrument has to be connected to mains by using a three wire mains
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 analyzer does not provide a mains switch and is operable when
connected to power.
