The outer packaging with current transformers is carried out according to the scope of the order and the method of transport in a transport package provided with labels and other data necessary for transport. The product must not be exposed to direct weather conditions during transport and storage. The product may only be stored in clean rooms free of conductive dust, aggressive gases and vapors. The most suitable storage temperature is 20 ° C.
Assembly description Das Modul kann auf zwei Arten montiert werden: entweder durch Montage auf der 35 mm breiten U-Schiene des Instrumententrägers ČSN EN 60715 oder durch Verschrauben von zwei Schrauben an der Basis (nach dem Ausfahren der Befestigungsklammern an der Unterseite des Moduls beträgt der maximale Schraubendurchmesser 4 mm). Die Abmessungen des Moduls und der Abstand der Löcher für die Montage des Moduls an den Schrauben sind in Abb. 1 dargestellt. Am Ort der Installation des Geräts und seiner unmittelbaren Umgebung muss eine natürliche Luftzirkulation zugelassen werden. Weitere Informationen zur Installation finden Sie im CFox-, RFox- und Foxtrot-Konstruktionshandbuch, Bestellnummer: TXV 004 16.
Connection description The module is connected with screw terminals. The measured voltages connect a suitable fuse element with characteristics according to the environment (eg fuse with a value of 0.5 A) to the terminals U, Va W, the middle conductor is connected to the common terminal N. Power supply of the module is realized via terminals U and N, therefore it is necessary that the terminal N is always connected to a suitable potential (in a delta connection or in an Aaron connection). The voltage measuring inputs are connected to the internal circuits via a high impedance. To connect the current inputs, it is necessary to use measuring current transformers with a secondary winding with a nominal value of 333 mVs corresponding to the measurement category / insulation voltage or to install the transformers on an insulated primary conductor with a corresponding insulation voltage. The secondary windings of the transformers are connected to terminals S1 and S2 of the current inputs I1, I2 and I3. All terminals S2 are galvanically connected to the same potential inside the module. If it is necessary to ground the secondary side of the measuring transformers, it is therefore necessary to connect terminals S2. The recommended conductor type for connecting the measured voltage and current is H07V – U (CY) cross section 0.5 mm2–2.5mm2. The CIB bus is connected to the CIB + and CIB– terminals. The number of modules on the CIB bus is limited by the maximum permitted bus current. The correct connection of the module, including the correct connection of current transformers, is illustrated in Fig. 2.

Module operation
Commissioning The module is ready for operation after connecting the supply voltage and the CIB bus. It does not contain any controls and is operated, set up and diagnosed from the MOSAIC programming environment. The address is indicated on the label on the front panel. When initializing the module, the correct value of the primary current INOM of the respective current transformers (current range) must be entered.

Note: CIB master CF-1140 / CF-1141 with FW version 2.0 and higher is required for correct module operation!

Attention: When working with the module, it is necessary to observe all necessary measures to protect people and property from injury and damage by electric shock!

The module must be operated by a person with the prescribed qualification for such an activity and this person must be thoroughly acquainted with the principles of working with the module. If the module is connected to parts that are under dangerous voltage, all necessary measures must be taken to protect users and equipment from electric shock. Workers installing and / or maintaining the equipment must be equipped with and use personal protective equipment and other safety equipment at work. If the module is used in a manner not specified by the manufacturer, the protection provided by the module may be reduced.

Further information can be found in the manual Peripheral modules on the CIB bus, order no .: TXV 004 13.01.
Module diagnostics The basic diagnostics are performed internally and the measurement results are available in the relevant registers of the Mosaic environment. The status of the module is indicated by the green RUN LED located on the front panel below the terminals for connecting the CIB bus. After connecting the CIB bus, the green RUN diode lights up and its light indicates the presence of the supply voltage on the CIB interface. After communication between the module and the central unit, the RUN LED flashes. This prepares the module for operation.
Description The module does not require any maintenance under general installation conditions. The operations in which a part of the module has to be dismantled must always be carried out with the supply voltage disconnected.
Notice Because the module contains semiconductor components, it is necessary to follow the principles for working with electrostatic sensitive components when handling the removed cover. It is not allowed to directly touch the printed circuit boards without protective measures !!!
Generally Warranty and complaint conditions are governed by the Terms and Conditions of Teco a.s.
Notice You must meet all the conditions of this documentation before turning on the system. The system must not be put into service unless it has been verified and confirmed that the machinery meets the requirements of Directive 89/392 / EEC, in so far as it applies to it. Documentation subject to change.
