Guide d'exploitation ATV62

Mounting RecommendationsGeneralEnsure that the input voltage (3-phase a.c.) is 400 V, ± 15 %, 50 / 60 Hz ± 5 %, or 500 V + 10 - 20 %, 50 /60 Hz ± 5 % respectively.Avoid harmful environments, such as those with high temperature and humidity levels as well as environments containing dust, dirt or corrosivevapours. The location must be well ventilated and away from direct sunlight.Install the equipment on a vertical surface which is fireproof and vibration-free.Warning! Do not apply line voltage to output terminals U, V, W.Consult the motor manufacturer if the motor is to operate at more than 60 Hz.The isolation resistance and dielectric strength of all inverters has been checked. During periodic inspections the power terminals may be isolatedfrom earth but the control terminals must under no circumstances be isolated from earth.START / STOP is by the control terminals or the keyboard, not by closing a contactor on the supply or output to the motor. The equipment is designedto be energized approximately 10 times per hour.Do not install capacitors or surge diverters on the motor cables.Distances from other equipment and surfacesTo ensure convection cooling, Altivar 62 speed controllers are designed for vertical installation. Observe the minimum recommended distances,especially if the equipment is flush-mounted.The ingress of objects during installation risks causing damage to the equipment : ensure that no objects, wires, wire insulation, swarf or dust enterthe equipment by covering it up when it is not connected to the supply.≥ 200 mm• Provide outside evacuationfor the warm air.150 mm(1)150 mm(1)ENGLISH≥ 100 mm• Provide ambienttemperature air entry.The temperature limits for the range must not be exceeded (see table). If the maximum temperature of the heatsink is reached, the switchingfrequency of the inverter is automatically reduced and, if this is not sufficient, current limitation is triggered. If the ambient temperature is increased,the service life of the inverter is reduced. Never install the equipment near a heat source.If the equipment is to be installed in an enclosure, allow for the heat dissipation. If necessary, install an auxiliary forced ventilation system.(1) The space to the sides is only required for access during maintenance. If the equipment can be easily removed, the space is not necessary.29
