9.1.3.1
CE-Compliant Structure of the Control Cabinet
In accordance with the EU Council Directive 89/336/EEC, converted in the EMC law for the
Federal Republic of Germany, from 1st January 1996, all electrical equipment within the
European Union must be labeled with the CE conformity marking for electromagnetic
compatibility (EMC).
All modules included in the HIQuad X system bear the CE marking.
To prevent EMC issues when installing controllers in control cabinets and support frames, the
following measures must be implemented:
The H 7034 filter must be installed close to the 24 V supply to suppress interferences directly
at the supply point.
Ensure proper and interference-free electrical installation in the vicinity of the controllers,
e.g., do not lay power lines together with field lines or 24 VDC supply lines. For further
information, see Chapter 9.1.3.2.
Observe the instructions provided in this manual related to grounding, shielding and cable
routing to sensors and actuators.
9.1.3.2
Surges on Digital Inputs
Due to the short cycle time of the HIQuad X systems, a surge pulse as described in
EN 61000-4-5 can be read in to the digital inputs as a short-term high level.
To prevent malfunctions, take one of the following measures for the application:
Install shielded input wires to prevent surges within the system.
Noise blanking in the user program: a signal must be present for at least two cycles before it
is evaluated.
Caution: This measure increases the system response time!
i
The measures specified above are not necessary if the plant design precludes surges within
the system.
In particular, the design must include protective measures with respect to overvoltage,
lightning, grounding and plant wiring in accordance with the relevant standards and the
manufacturer's specifications.
