The following table shows the data relevant for mounting. Table 1: Relevant data for mounting Design Weight Standard version: … kg depending on equipment Wide version: … kg depending on equipment Installation type HMI: semiflush on the LV door Central unit: in the LV compartment Dimensions 185 x 244.8 x 261.5 mm (W x H x D) Standard version 229 x 244.8 x 261.5 mm (W x H x D) Wide version Panel cutout 206 x 121 mm (W x H) 4.2.1 Set-up Area and Required Environmental Conditions Please note the following information regarding the set-up area: Allow sufficient space for access to the. The connections must be easily accessible. Access to the Central Unit in the LV compartment must be easy for the following reasons: to replace the unit, to expand the unit, to replace specific electronic equipment boards and to replace specific modules if necessary. Because the unit is sensitive to non-permitted severe environmental conditions, please observe the following: The set-up area must be free of excessive air contamination (dust, aggressive substances…). The natural air circulation around the unit must be free. The set-up area must maintain the specified environmental conditions REF 542plus s

To test the phase sequence, set every phase separately to the rated value and then check the value on the LC display screen. At the end reset the phase to zero. Generate one symmetrical system each for current and voltage with the rated values. Check the calculated values. A three-phase current and voltage tester is recommended to test the power. By changing the phase angle between the current and the voltage system the calculation of reactive and effective values and of cos ϕ can be checked. 5.7 Testing the protective functions To ensure that no damage has been caused by transport or setup and installation of the protection equipment and systems, secondary tests are run on the REF542plus protection and control unit with the configured protective functions. Warning! Always observe the applicable safety regulations when conducting the secondary test with an appropriate test set. Caution When testing ensure that the limit values of the measuring inputs and the auxiliary voltage supply are not exceeded. Secondary function tests are recommended during commissioning of the protective functions. The activated and configured automatic auto reclosure and also other functions of the complete system and the power circuit-breaker should be tested to ensure safe operation of these functions. The following points are particularly important for protective functions that must work in connection with a set direction or energy flow quantity. Checking the sensor and transformer connections and wiring check of the station circuit diagram Determining the transformer direction Connection and documentation of the test set Testing and documentation of the measured value recording Setting parameters for the protective functions Recording the test settings To monitor the test of the correct direction of the specific protective functions in comparison with the measured power and power factors in the event of a later primary test, the following information should be documented in the secondary tests: Directional setting of the test set Measurement of the effective and reactive power and of the cos ϕ factor Directional setting of the measurement and protective functions
