2.10 Installation and operation

Í Í Í
!
Certain parts of electrical appliances are inevitably under hazardous voltage
during operation. Grievous physical injury or damage can occur if the operating
instructions are not heeded.
The installation and connection of the appliance must only be carried out by
suitably qualifi ed personnel.
In particular, all safety warnings must be observed.
Installation
• The installation point should be as free from vibrations as possible. The
permissible ambient temperature (working or functional temperature) must
be observed (see Technical specifi cations).
• Operation outside the functional temperature range can result in incorrect
measurement and may lead to a failure of the transducer.
• Plastic housing, overvoltage category III according to DIN EN 61010 part 1.
• Screw terminals for max. 2.5 mm ² or 4 mm ² .
• The transducer can be snapped onto a 35 mm top-hat rail (according to DIN
EN 50022).
• The units are certifi ed only for operation in closed housings or cubicles.
Connection
The regulations concerning the electrical installation of power systems must be
complied with.
• If several receiving units, e.g. recorders, indicators, telecontrol systems,
computers or closed-loop controllers are to be used, they should be connected
in series with the current output of the transducer (pay attention to the
polarity!).
• The auxiliary power connection must be protected externally.
• The entire load, including the wiring, must not exceed the maximum value
given in the technical specifi cations.
• The terminal assignment is described in section 2.9.
