InstallationFor installation/operation, the provisions of EN 60079 part 14 and/or local authority regulations in accordance with directive 1999/92EC apply, as to generally accepted engineering practice and this Instruction Manual.The motor complies with the requirements of directive 2014/34/EU (ATEX) provided that the design criterion given from the manufacturer and this Instruction Manual are met. In particular the observance of threshold values of voltage, current and speed play an important role.5.1 Mounting:On factory site you have to check the machine type of protection is in accordance to the environmental conditions. Free access to the terminal boxes lubricant and control devices is required.Ventilation air inlets are to be free and you have to ensure that no warmed ventilation air can be taken (consider neighbouring equipment).Dismantle anticorrosive coating. No soiling shall impair the machine interior. Damaged painting shall be touched up.The machine shall be securely mounted to a most possible vibration and shock-free base.The machine is fitted with a canopy for the fan cowl, preventing foreign objects from falling into the ventilation openings. This canopy must be prevented from damages.Align the machines carefully to ensure smooth running. Axial deviation and deviation of parallel surfaces of both coupling halves must be not more than 0.01mm considering the heat extensions.Please observe the instructions of the manufacturer of the driven machine and the coupling too.Seite 5AC-Motoren GmbH Telefon 06071-49887-0 Sparkasse Dieburg Postbank FrankfurtPermissible torque settings of machine mounting bolts:After alignment the machine feet are recommended to be fixed to the base.The alignment behaviour shall be checked in appropriate time (8000 operation hours)The motor is intended for the use of a flexible coupling and the direct drive.The rotor is balanced with half-key (balancing quality G2.5) The coupling has to be dynamic balanced correspondingly.The mounting of this coupling must be realized by appropriate means. Shocks may damage the bearings! Test run with the feather key fitted without a coupling halve is not permitted due to the key!For the installation to driven and transmission components their meeting of the ATEX requirements must be provided!Coverage of transmission components shall be provided.When for special cases torque shocks (blocked rotor, heavy starting) shall be considered, the hazard of mechanical breakage of overheating of the motor and the resulting ignitionrisk must be prevented by mechanical protection devices.5.2 Electrical Connection:All mounting and installation works must be done by experienced personnel in accordance with EN 60079 part 14 and local authority regulations.And they must be carried out on standstill machine, isolated and secured against reconnection only. Check safe isolation from supply! This also applies for auxiliary circuits.The stator winding is to be connected resulting in the clockwise shaft rotation for the line connection L1, L2, L3 to terminals U1, V1, W1 and anti-clockwise rotation for connection to W1, V1, U1. The Delta of Star connection has to be made on the main terminals.Line cable and their installation shall adhere to EN 60079-14. Observe the degree of protection level especially (sealing).Short circuit safety of the terminals box is only assured for use of cable cross-sections and cable lugs in accordance with DIN 46235 or adequate hexagon lugs. Due to dynamic short circuit strain pull out damage of the cable lug may occur.In the case of cables with outside armouring the latter must not be entered to the terminal box. It should simply be taken to the strain-relief point then arranged outside in order to prevent moisture from penetration into the terminal box. The connection lead shall be sealed in the entry opening by means of a sealing insert capable of being cut out.Connection of auxiliary circuits is to be made by the means of two separate terminals in the terminal box.Only separately certified cable glands are permitted usable for hazardous areas zone 2/22. Unused entry openings should be closed off with dummy plug, same way certified.All of the motor terminals boxes are designed separately certified for the use in hazardous areas. During installation the creep age and clearance distances considering the cable and lugs must be observed in particular.The connections must be made as to maintain a permanent safe electrical connection with appropriate cable terminals, permissible cable type and wiring system and safe equipotential bonding. Take care of the mounting of cable entries, self-loosing prevention, permanent sealing of the entries and temperatures of entry and cable (70°C max.)Exceeding of the tolerances specified by EN 60034-1 (i.e. voltage +/-5%, frequency +/-2%, waveform, symmetry) leads to elevated temperatures affecting the permitted surface temperatures and the category 3G/D use of the machine.Permissible torque settings of terminals and cover bolts:You have to assure by appropriate circuitry interlock that the motor operation is only possible with fault-free ventilation. If not, there is a hazard of exceeding the maximum permissible surface temperature.Refer to the electrical connection diagram enclosed with the terminal boxes when wiring the PTC temperature sensors.Furthermore there are required electrical protection measures against overload and two phase operation.The motor must be connected to the local grounding system.Seite 6AC-Motoren GmbH Telefon 06071-49887-0 Sparkasse Dieburg Postbank Frankfurt5.3 Winding Insulation:Before the first start up and after long time non-operation the insulation resistance of the motor winding must be measured (stator winding against machine housing).This has to be done using appropriate measuring instruments having 500V DC test voltage at least.Permissible insulation resistance is:If these values are failed, the winding must be dried out. The appropriate measure depends on the local equipment and shall be negotiated with the manufacturer (drying out oven, current, hot ait, space heater).For each case the maximum temperature of the winding shall not exceed a 90°C temperature as the maximum.It has to be observed while drying out.Reading the insulation resistance at three-hours intervals, the drying procedure should be stopped two or three hours after the insulation resistance reaches the required value.It should be noted that the insulation resistance reading measured after the machine has cooled may be higher than the value obtained with the machine hot at the time when drying was stopped.5.4 Starting conditions:It is permitted•Having ambient temperature status, three continuous starting are allowed, but there should be a natural stopping between them•The next starting needs a 30min interval when there was a natural stopping•Having rated running temperature status, starting twice is allowed•For further starting a cooling interval of 4 hours is required•Starts with having rest voltage are not allowedSeite 7AC-Motoren GmbH Telefon 06071-49887-0 Sparkasse Dieburg Postbank Frankfurt5.5 Checks prior to start-up:Check before starting the motor:•Motor and driven machines are correctly coupled and fixed together•Safety covers on moving parts are fitted, in position and fixed to the floor or a fixed object•Nobody is working on the machine•There are no loose objects in or on the machine•Complete installation is suitable for the starting of the motor•Frame is correctly earthed, offering proper protection for workers•Electrical power and instrument connections comply with the wiring diagram•Power cables are correctly fitted to the motor terminals•All protection devices are operational, grease nozzles are clean•Covers and inspection hatches are closed•Protection degree and certification level of the electrical motor and all accompanying equipment is suitable for the risks and conditions of the area in which it is to operate5.6 Checks during start-up:Check if the motor is running:•Motor is turning in the right direction•There are no abnormal vibrations on the bearings:•Immediately after start-up, after 1 hour and after 4 hours running•There are no abnormal temperature on bearings and housing•There are no abnormal noises5.7 On-going checks•The readings given by the safety devices (temperature of the bearings and wiring) must be remain within the set limits.Seite 8AC-Motoren GmbH Telefon 06071-49887-0 Sparkasse Dieburg Postbank FrankfurtSeite 9AC-Motoren GmbH Telefon 06071-49887-0 Sparkasse Dieburg Postbank Frankfurt6.
