Installation notes
CAUTION!
The delivery status of the device at the first startup does not necessarily correspond to the
intended application (for example, Controller 2 inactive).
This may result in undefined plant behavior.
Therefore, where possible during startup, no actuators should be connected and load cur-
rent circuits should be isolated. The plant installer is essentially responsible for the startup
process.
6.1.1
Cables, shielding, and grounding
When selecting the electrical wiring material as well as when installing and connecting the con-
troller electrically, comply with the requirements of DIN VDE 0100 "Low-voltage electrical instal-
lations" and the applicable country-specific regulations (for example, based on IEC 60364).
•
Where possible, route input, output, and supply cables separately and not parallel to one
another.
•
Only use shielded and twisted probe and interface cables and where possible, route them
at a distance from components or lines that are live.
•
For temperature probes, ground the shielding on one side in the control cabinet.
•
Do not perform loopthroughs on the grounding cables, but route the cables individually to a
shared grounding point in the control cabinet; in doing so, ensure that the cables are as
short as possible.
•
Ensure potential equalizer is correctly routed.
6.1.2
Electrical safety
•
The primary fuse protection for the voltage supply should not exceed a value of 20 A (pas-
sive) and should not be less than 2 A.
•
In order to prevent the destruction of the relay or solid state relay outputs in the event of an
external short circuit in the load circuit, the load circuit should be fused to the maximum ad-
missible output current.
•
In addition to a faulty installation, incorrectly set values on the controller could also impair
the correct function of the following process. Therefore, ensure that safety devices indepen-
dent of the controller (for example, overpressure valves or temperature limiters/monitors)
are available and that it is only possible for qualified personnel to define settings. Please
observe the corresponding safety regulations in this context.
•
Since not all existing control paths can be controlled with the setting function, the stability
of the actual value reached should be monitored.
6.1.3
Intended use, misuse
•
The controller is intended for use in the industrial sector.
WARNING!
The controller is not suitable for installation in areas with an explosion hazard
There is the risk of an explosion.
The device must only be used outside of areas with an explosion hazard.
