Ensure all supplies are de-energisedbefore attempting connection or other procedures.• Terminals should not be user accessible afterinstallation and external installation provisions mustbe sufficient to prevent hazards under fault conditions.• This unit is not intended to function as part of asystem providing the sole means of fault protection -good engineering practice dictates that any criticalfunction be protected by at least two independent anddiverse means.• The unit does not have internal fuses thereforeexternal fuses must be used for protection and safetyunder fault conditions.• Never open-circuit the secondary winding of anenergized current transformer.• If this equipment is used in a manner not specified bythe manufacturer, protection provided by theequipment may be impaired.• Auxiliary circuits (communication & relay outputs) areseparated from metering inputs and 110-400V auxiliarycircuits by at least basic insulation. Such auxiliarycircuit terminals are only suitable for connection toequipment which has no user accessible live parts.The insulation for such auxiliary circuits must be ratedfor the highest voltage connected to the instrumentand suitable for single fault condition. The connectionat the remote end of such auxiliary circuits should notbe accessible in normal use. Depending onapplication, equipment connected to auxiliary circuitsmay vary widely. The choice of connected equipmentor combination of equipment should not diminish thelevel of user protection specified.92.0Cutout DetailsThe unit may be mounted in a panel of any thickness up to amaximum of 6 mm (0·25in). Leave enough space behind theinstrument to allow for bends in the connection cables. As thefront of panel enclosure conforms to IP52, it is protected fromdripping water. The unit is intended for use in a reasonablystable ambient temperature within the range -10 to +55°C. Donot mount the unit where there is excessive vibration or inexcessive direct sunlight.SafetyThe unit was designed in accordance with BS EN 61010-1:2001(IEC 61010-1:2001) – Permanently connected use, Normalcondition. Installation category III, pollution degree 2, basicinsulation for rated voltage. Measurement Category III.EMC Installation RequirementsWhilst this unit complies with all relevant EU EMC (electromagneticcompatibility) regulations, any additional precautionsnecessary to provide proper operation of this and adjacentequipment will be installation dependent and so the following canonly be general guidance:• Avoid routing wiring to this unit alongside cables andproducts that are, or could be, a source of interference.• The auxiliary supply to the unit should not be subject toexcessive interference. In some cases, a supply line filtermay be required.• To protect the product against incorrect operation orpermanent damage, surge transients must be controlled. Itis good EMC practice to suppress transients and surges atthe source. The unit has been designed to automaticallyrecover from typical transients; however in extremecircumstances it may be necessary to temporarily disconnectthe auxiliary supply for a period of greater than 10 seconds torestore correct operation.• Screened communication leads are recommended and maybe required. These and other connecting leads may requirethe fitting of RF suppression components, such as ferriteabsorbers, line filters etc., if RF fields cause problems.• It is good practice to install sensitive electronic instrumentsthat are performing critical functions in EMC enclosures thatprotect against electrical interference causing a disturbancein function.

WiringInput connections are made to screw clamp terminals. Choice ofcable should meet local regulations for the operating voltage andcurrent. The current inputs of this product are designed forconnection into systems via current transformers only.Instrument transformers used for connection to the meter mustbe of approved type and compliant with ANSI/IEEE C57.13 orIEC 60044-1, selected and sized appropriate to the supplynetwork being monitored. All negative current inputs arecommoned inside the unit and grounding should be at one pointonly. To minimise measurement errors, the CTs should begrounded as shown in the wiring diagram. CT secondaries mustbe grounded in accordance with local regulations. It is desirableto make provision for shorting links to be made across CTs topermit easy replacement of a unit should this ever be necessary.All connections are made to screw clamp terminals. Terminalsare suitable for copper wires only and will accept one 0·05 –2·5mm² (30 – 21AWG) stranded or solid core cable. Instrumentsare intended for panel mounting. Terminals must be enclosedwithin the panel. Use wire rated at 600V for main terminals, 60°Cminimum temperature. Terminal screws are fully tightened forshipment and must be undone before wire insertion. Terminalscrews should be tightened to 0·5Nm (4·4 lbf in) only.Additional considerations for three wire systemsThe neutral terminal (terminal N) is indirectly connected to thevoltage input terminals (terminals L1, L2, L3). When connectedto a three wire system the neutral terminal will adopt a potentialsomewhere between the remaining lines. If external wiring isconnected to the neutral terminal it must be connected to eitherthe neutral line or earth (ground) to avoid the possibility of electricshock from the neutral terminal.FusingThis unit must be fitted with external fuses in voltage andauxiliary supply lines. Voltage input lines must be fused with afast blow fuse 1A maximum. Auxiliary supply lines must be fusedwith a slow blow fuse rated 1A maximum (if product is poweredline-to-line, ensure both lines are fused). Choose fuses of a typeand with a breaking capacity appropriate to the supply and inaccordance with local regulations.A suitable switch or circuit breaker confirming to the relevantparts of IEC 60947-1 and IEC 60947-3 should be included in theinstallation. It should be positioned so as to be easy to operate,in close proximity to the equipment, and clearly identified as thedisconnecting device.Earth/Ground ConnectionsFor safety reasons, current transformer secondary connectionsshould be grounded in accordance with local regulations. Underno circumstances should the product be operated without anEarth connection.MaintenanceIn normal use, little maintenance is needed. As appropriate forservice conditions, isolate electrical power, inspect the unit andremove any dust or other foreign material present. Periodicallycheck all connections for freedom from corrosion and screwtightness, particularly if vibration is present.The front of the case should be wiped with a dry cloth only. Useminimal pressure, especially over the viewing window area. Ifnecessary wipe the rear case with a dry cloth. If a cleaning agentis necessary, isopropyl alcohol is the only recommended agentand should be used sparingly. Water should not be used. If therear case exterior or terminals should be contaminatedaccidentally with water, the unit must be thoroughly dried beforefurther service. Should it be suspected that water might haveentered the unit, factory inspection and refurbishment isrecommended.In the unlikely event of a repair being necessary, it isrecommended that the unit be returned to the factory or nearestCrompton Instruments / TE Connectivity service centre.SpecificationMeasurement InputsImported and exported energies are recorded.Three current inputs (six physical terminals) with 2·5mm²stranded wire capacity for connection of external CTs.
