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!
CAT 200 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 junction box must be protected by fuse supply (10 A fuse) which has a
breaking capacity adjusted to the short circuit of the equipment.
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.
5.4.5.2 Electrical Connections
To ensure protection against water and dust use cable glands with minimum
IP 65 classification!
The junction box provides at its left side one threat M20x1.5 and at its right
side up to three threats M16x1.5 for installing cable glands.
The left gland is the mains power cord entry, the right side glands for signal
cables.
Not used threats must be sealed by approved sealing plugs (factory delivery
condition).
