Do the ATV61 and ATV71 ranges ending with (S6X) 575V drives have conformal coating on the circuit boards as standard?Is the reinforced verdion (S337) option available for these drives ?

S337 specification add conformal coating and DC bus bars are nickel-plated. These are in standard only for the drive over 75kW.
For our spare parts there are no difference between S337 and standard for the varnishing : all have reinforced varnishing.
