31. MIDA IntroductionMIDA is a variable frequency drive (inverter) designed to control and protect pumping systems by varying the outputfrequency to the pump.MIDA can be applied to both new and existing pumping systems providing: energy and cost savings simplified installation and an overall lower pumping system cost longer life of the pumping system and relevant components improved reliabilityMIDA, when connected to any pump, manages the system operation to maintain a certain constant physical quantity(pressure, differential pressure, flow, temperature, etc.) regardless of water demand. The pump is operated only whenneeded thus avoiding unnecessary energy consumption.MIDA at the same time is able to: protect the motor from overload and dry running implement soft start and soft stop to increase the system life and reduce current peaks provide an indication of current consumption, voltage, and power maintain a record of run time and display any errors and/or failures reported by the system connect to other MIDA units for combined operationMIDA can be installed on motor terminal box or fixed on the wall.In the last case, through the use of output filters it is possible to reduce dangerous surges that are induced in long cables,making MIDA suitable for control also of submersible pumps.2. Safety InstructionsThe manufacturer strongly suggests carefully reading this operation manual before using and installing its products.Any operation (installation, maintenance and repair) must be carried out by trained, skilled, and qualified personnel.Failure to observe and follow the instructions in this manual may result in dangerous and potentially lethal electric shock.Pay attention to all standard safety and accident prevention regulations.The device must be connected to main power supply via a switch to ensure the completedisconnection from the network before any operation on the MIDA itself (including visualinspection) and/or on the connected load.Disconnect MIDA from the main power supply before commencing any work.Do not open the device without having first disconnected the device from the main power supplyand having waited at least 5 minutes.MIDA and pumping system must be grounded properly before operation.For the entire period MIDA is powered, high voltage could be present on the output terminals ofthe inverter whether or not the pump is running.Tightening all screws on the cover with washers is recommended before powering the device.Otherwise, there may be a failure to connect the cover to ground, creating the risk of electricshock or even death.Avoid any shock or significant impact during transport.Check the MIDA immediately upon delivery and check for damage and/or missing parts. If either occurs, immediately notifythe supplier.Damages due to transport, incorrect installation, or improper use of the device will null and void the warranty.Tampering or disassembly of any component will automatically void the warranty.The manufacturer cannot be held responsible for any damages to people and/or property due to improper use of itsproducts. |
