Section 3 Installation
D A N G E R
Only qualified experts should conduct the tasks described in this section.
D A N G E R
Select an appropriate installation location 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 dangers and fire hazard. Use only the supplied power cable.

Note the weight (control unit approx. 22 kg, module carrier with 5 m suction tube approx.

lifting devices for the transport.
