Power Quality ManagementOperating InstructionsPQM500 & PQM300 Series2Page 5 of 12General data of the system2.1 Technical data - nameplate You will find the technical data of your system on your system’s nameplate which is located onthe inside of the door. Every assembly module also has its own nameplate on the front. Pleasecheck before connecting to the low voltage network that the mains data shown on thenameplate, such as nominal voltage, nominal frequency and network configuration, match theconditions on site.2.2 Ambient conditions The permitted ambient conditions depend on the system’s degree of protection. You will find thison the nameplate. The standard degree of protection is IP20.The following table provides information about the significance of the IP code:Protection against solid bodies1stDescriptionnumeral0no protection1Solid bodies 50 mm2Solid bodies 12.5 mm3Solid bodies 2.5 mm4Solid bodies 1 mm Protection against water2ndDescriptionnumeral0no protection1Dripping water falling vertically2Dripping water falling at an angle of 15 3Spray water falling at an angle of 60 4All-round protection against spraywaterClimatic conditions:Relative humidity: max 95%, non-condensingDo not use the systems in corrosive environments; environments containing chlorine, sulphur, acidor salt may damage the system.PQM 500:maximum ambient temperature: 40 CWe recommend an ambient temperature of 25 C for an extended lifetime of the capacitors.PQM 300:maximum ambient temperature: 40 CWe recommend an ambient temperature of 25 C for an extended lifetime of the capacitors.

Power Quality ManagementOperating InstructionsPQM500 & PQM300 SeriesPage 6 of 122.1 Intended use 3Compensation systems of type PQM 300 & PQM 500 are used for the incoming supply ofcapacitive reactive power. The power discharged can either be controlled by a reactive powercontroller or can be set to a fixed value.Subsequent technical modifications to the systems, in particular the use of capacitors, fuses orcontactors with different technical parameters or third-party components, without consulting MRis prohibited for reasons of safety.It is also prohibited to carry out modifications to protective covers, safety equipment and safetysettings without consulting MR.Installation and Commissioning Remove the packaging and transport materials at the installation site. Check the system fortransport damage prior to installation.Set up the system on a firm foundation in a stable position; its weight is shown in the circuitmanual. Caution, the system may be top-heavy when being transported on the pallet truck. Takecare during installation that none of the system’s ventilation openings are covered up, the rear airinlet vent of the PQM 300 in particular must remain open (maintain distance from wall, seecircuit manual). Connect the system to the grid. Dimension your leads according to the rated current of the fuseprotection, the type of lead and the type of installation, if necessary allowing for additionalderating factors depending on local conditions. Select the compensation system’s fuse protectionaccording to EN DIN IEC 60269-5. Test the connection according to the applicable standards. Connect the control wires according to the circuit manual. Pay attention to the polarity of thecurrent transformer and open all existing short-circuiting jumpers after installation. Themeasurement must be situated upstream of the connection point between system and grid in thedirection of the incoming supply. Energize the system and then parameterize the controller. There are dedicated operatinginstructions for operating the controller. First of all, use the controller’s automated initialization;in this case, the controller adjusts automatically to the connections and compensation stepsprovided. Test the controller’s measurement because efficient control can only take place if measuring iscorrect:o The measured current must match the measuring instruments of its incoming supplyotherwise the current transformer’s ratio must be adjusted in the controllero The voltage should correspond to the rated voltageo If the current and voltage measurement are correct but the power or the power factor isnot feasible, correct the phase difference between current and voltage measurement inthe controller’s settings. Test the controller’s setting:o The target power factor should be set to 0.98io Test the alarm output to the outside and remote control from outside if presento Your system is now ready for operation; the controller should now switch the steps onand off according to the reactive power demand when load changes occur.o The roof fans, if present, should switch on in a controlled manner Maschinenfabrik Reinhausen GmbH 2012.Manual PQM500 PQM300 Rev05 en.docx

The corresponding upstream circuit breaker or fuse circuit is used to isolate the system or if thereis no internal switchgear present. Notes: With compensation systems connected parallel to equipment without internal switchgear,switching off of the upstream circuit breaker leads to shutdown of the drive!WarningFor capacitive compensation steps, it is imperative to adhere to the dischargetime of 3 min specified by the manufacturer.The system’s busbar is energized in the switched off state.DangerThe contactor-switched capacitor steps are loaded with a dangerous residualvoltage during the discharge time!In thyristor systems, the capacitors are charged to the grid’s peak voltageeven when the thyristors are switched off!Warning/noteIt is imperative to observe the 5 safety rules prior to working on the system(see Section 1.2) Maschinenfabrik Reinhausen GmbH 2012.Manual PQM500 PQM300 Rev05 en.docx
