Packaginng, transportation, storage
Description The module with current transformers is packed in a paper box. This documentation is also part of the package. External packaging 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.
Installation
Description The module can be mounted in two ways: either by mounting on the instrument support U rail 35 mm wide ČSN EN 60715, or by screwing three screws to the base (after extending the three fastening clips located at the bottom of the module, max. screw diameter is 4 mm). The dimensions of the module and the spacing of the holes for mounting the module on the screws are shown in Fig. 1. At the place of installation of the device and its immediate natural air circulation must be allowed in the surroundings. More information on installation can be found in the Design Guide CFox, RFox and Foxtrot, order no .: TXV 004 16.
Connection
Connection description The module is connected with screw terminals. The measured voltages are connected to the terminals U, Va W via a suitable fuse element with characteristics according to the environment (eg fuse with a value of 0.5 A), the middle conductor is connected to the common terminal N. The module is powered 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
Warnings / Cautions The current inputs can never be used for direct current measurement! Using and connecting the wrong current transformer can seriously damage the module!

Module operation
Module configuration odul je po připojení pomocného napájecího napětí a sběrnice CIB připraven k činnosti. Neobsahuje žádné ovládací prvky a je obsluhován, nastavován a diagnostikován z programovacího prostředí MOSAIC. HW adresa je uvedena na štítku na předním panelu. Modul musí být obsluhován osobou s předepsanou kvalifikací pro takovou činnost a tato osoba se musí podrobně seznámit se zásadami práce s modulem. Pokud je modul připojen k částem, které jsou pod nebezpečným napětím, je nutné dodržovat všechna nezbytná opatření k ochraně uživatelů a zařízená před úrazem elektrickým proudem. Pracovník provádějící instalaci a/nebo údržbu zařízení musí být vybaven a při práci používat osobní ochranné pomůcky a další bezpečnostní prostředky. Je-li modul používán způsobem, který není specifikován výrobcem, může být ochrana poskytovaná modulem snížena. Další informace lze nalézt v příručce Periferní moduly na sběrnici CIB, obj. č.: TXV 004 13.01.
Commissioning The module is ready for operation after connecting the supply voltage. It does not contain any controls and is operated, set up and diagnosed from the MOSAIC programming environment. The HW 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.

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.
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 an LED on the front panel. When the supply voltage is connected, the diode lights up and its light also indicates the presence of power supply. After communication is established, the module is ready for operation.
Maintenance
Instructions The module does not require any maintenance if the general conditions for installation are observed. The operations that require the module to be assembled or disassembled are always performed with the auxiliary power supply disconnected and the measuring inputs disconnected.

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.
Warranty
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.
