Section 3 Installation
DANGER
Only qualified experts should conduct the tasks described in this section.
DANGER
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 if the equipment has not been
wired and fused correctly.
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 equipment is to be installed outdoors, switch the overload protection
between mains and 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).
