SIMEAS-T - Transducer without auxiliary power

10 Mounting and operation
WARNING!
When electrical devices are operated, certain parts necessarily conduct dangerous
voltages. Failure to heed the operating notices can therefore lead to serious injury or
property damage.
The device should only be mounted and electrically connected by appropriately
qualified personnel. In particular, all warning notices must be observed.
10.1 Installation
•
The installation location must be as free of vibrations as possible. The permissible
ambient temperature (operating or functional temperature) must be observed
(see technical specifications).
•
Operation outside the functional temperature range can lead to erroneous
measurements and failure of the transducer.
•
Plastic enclosure, overvoltage category III in accordance with DIN EN 61010 Part 1.
•
Screw terminals for maximum 2.5 mm
2
or 4 mm
2
.
•
The transducer must be mounted on a 35 mm DIN rail (in accordance with
DIN EN 50022). The DIN rail must be mounted horizontally.
10.2 Connection
The regulations for the construction of high voltage installations must be observed when
carrying out the electrical installation.
•
If multiple receivers are used, for example recorders, displays, remote terminal
units, computers or controllers, these devices must be connected in series with
the current output of the transducer (ensure correct polarity). For transducers
with voltage output, the receivers are connected in parallel to this.
•
The total load, including the cables, must not exceed the value stated in the
technical specifications.
•
The pin assignment is shown in section
8 Description
.
•
The performed installation must be tested according to EN 61439.
Notes for the fuses to be used:
Appropriate protection must be provided for the measuring circuits during the
installation:
•
Current measuring circuits: the fuse must prevent the values presented in the
table
6
Technical specifications
from being exceeded.
•
Voltage measuring circuits: the fuse must limit the current to 100 mA,
be suitably arranged and be easily accessible to the user.
10.3 Installation material
Measuring circuits: The connection of the measuring circuit must be made with cables
that have demonstrated double isolation for the highest voltage occurring in the
measuring circuit.
