Section 3 Installation
D A N G E R
Only qualified experts may conduct the tasks described in this section.
D A N G E R
Select a suitable attachment point for the instrument.
Plan out the mechanical mount·before positioning poles or drilling holes. Make sure the mount
has a sufficient bearing capacity. The dowels must be selected and authorized according to the
condition of the wall.
The manufacturer shall accept no liability if the instrument is installed incorrectly.
Plan how to lay cables and tubes and their path in advance. Lay the tubes, data cables and
power cables without any bends and so they do not pose a tripping risk.
Do not connect the electrical supply to the mains·until the instrument is completely wired and
protected against short circuits.
Sufficiently protect the electrical power supply against short circuits.
For the external power supply, always connect a residual-current circuit breaker·(trip current
max.: 30 mA) between the mains and the system.
If the instrument is to be installed outdoors, connect a surge arrester between the mains and the
system.
Products intended by the manufacturer for outdoor use offer a higher level of protection against
the penetration of liquids and dust. If these products are connected to a mains outlet with a cable
and plug·rather than a permanently connected cable, the plug and outlet are much more
susceptible to liquid and dust penetration. The operator must sufficiently protect the plug and
outlet against liquid and dust penetration in accordance with local safety regulations. If the
instrument is to be used outdoors, it must be connected to a suitable outlet with a protection type
of at least IP44 (splash protection).
WA R N I N G
Electrical and fire hazards. Only use the mains cable supplied. Only qualified experts may
perform the tasks described in this section of the manual, while adhering to all locally valid safety
regulations.
N O T I C E
Protect the instrument from extreme temperatures from heaters, direct sunlight and other heat
sources.
C A U T I O N
Beware of the weight (open loop control unit: approximately 12 kg; sampling probe up to
approximately 22 kg) of the instrument and the probe. Do not attempt to carry the instrument and
probe without assistance. Use only suitable lifting devices for the transport.
