Mounting is by two corner clamps and thumb screws. Consideration should be given to the space required behind the unit to allow for bends in the connection cables. As the enclosure conforms to IP54 it is protected against ingress from water spray from all directions, additional protection to the panel may be obtained by the use of an optional gasket. The terminals at the rear of the case should be protected from liquids. INTEGRA 2000 should be mounted in a reasonably stable ambient temperature and in any event where the operating temperature is within the range 0-50°C. INTEGRA 2000 should not be mounted where it will be subjected to excessive direct sunlight. Vibration should be kept to a minimum. For optimum viewing INTEGRA 2000 should be mounted so that the operator views the display as shown below. Side labels show full connection information and data. It is good EMC practice to suppress differential surges (caused by contactors, tap changes, sensitive switching, etc.) to 2.2kV at the source. Caution 1. In the interest of safety and functionality this product must be installed by a qualified engineer. 2. Under normal or single fault conditions voltages dangerous to human life may be present at some of the terminal connections of this unit. Ensure that all supplies are de-energised before attempting any connection or disconnection. 3. These products do not have internal fuses therefore external fuses must be used for protection for safety under fault conditions. 4. The current inputs of these products are designed for connection into systems via current transformers only. 3 Ideal Viewing angle EMC Installation Requirements This product range has been designed to meet the certification of the EU Directives when installed to a good code of practice for EMC in industrial environments. e.g. 1. Screen output and low signal input leads. Other connecting leads must be screened or have provision for fitting RF suppression components, such as ferrite absorbers, line filters etc., if RF fields cause problems. N.B It is good practice to install sensitive electronic instruments, that are performing critical functions, in EMC enclosures that protect against electrical interference causing a disturbance in function. 2. Avoid routing leads alongside cables and products that are, or could be, a source of interference. 3. To protect the product against permanent damage, surge transients must be limited to 2.2kV pk. The unit has been designed to automatically recover in the event of a high level of transients. In extreme circumstances the auxiliary supply may have to be momentarily disconnected to restore correct operation. 4. ESD precautions must be taken at all times when handling this product. For assistance on protection requirements, please contact your local sales office.

Numbering is clearly marked on the plastic moulding. Choice of cable should meet local regulations. Terminals for both current and voltage inputs will accept up to 3mm2 x 2 diameter cables. Auxiliary Supply - INTEGRA 2000 ideally should be powered by a dedicated supply, however it may be powered by the signal source, providing the source remains within ±10% of the chosen auxiliary voltage. Fusing - It is recommended that all voltage lines are fitted with 1 amp HRC fuses. Earth/Ground Connections - For safety reasons, CT secondary connections should be grounded according to local codes of practice. Import/Export Connections - The connections shown assume an import power configuration and therefore power factor is shown as import (IMP). Current will flow towards the load, if current flows away from the load, in an export power situation, then the power factor indication will change to export (EXP). This negates the need for separate export connections, because Integra serves the full four conditions of power factor. 5 Operating Instructions Power measurement made easy with INTEGRA 2000 On power up and in normal operation the INTEGRA 2000 displays the initial screen. This screen is factory set to display “Volts”, “Amps”, “Frequency” and “Watt”. It may be changed to display any four parameters. See the customisation section later in this guide. The INTEGRA 2000 screen 6 The standard viewing screen has four active readings indicated. By character size and one key soft prompt. 1st size Largest characters - the active readings. Four digits with dynamic scaling. 2nd size The parameters for active readings with dynamic scaling to reflect Kilo, Mega etc. 3rd size Indicate the relationship of the active reading to the measured system, e.g. L-L, sum etc. 4th size Smallest characters - offers the key legends which guide the user through the menus of the instrument. “Next” is the only available key function on this screen. Press the “NEXT” key. The default screen now reduces in size to reveal the first level of key legends, all readings are still active. Each key now takes the user down to a new level of the menu structure. This can be demonstrated by pressing ”Power” Press “POWER” The first level power screen by default shows active readings of W, VAr, VA and PF PA. (From this level down exiting all screens is easily done by a single keystroke “Exit”.)
