EN – R6…R9 Quick installation guide 13R0-R4R6-R9R6-R9ENDADEESFIFRITNLPLPTRUSVTRZHZHmotor must exceed 100 Mohm (reference value at 25 °C or 77 °F). For theinsulation resistance of other motors, see the manufacturer’s instructions.Note: Moisture inside the motor casing will reduce the insulation resistance. Ifmoisture is suspected, dry the motor and repeat the measurement.Check the compatibility with IT (ungrounded), corner-grounded delta, midpoint-grounded delta, and TT systemsSee figure C on page 31. EMC filterA drive with the internal EMC filter connected can be installed to a symmetricallygrounded TN-S system. If you install the drive to another system, you may need todisconnect the EMC filter. See section Checking the compatibility with IT(ungrounded), corner-grounded delta, midpoint-grounded delta, and TT systems (forIEC) in ACS580-01 (0.75 to 250 kW, 1.0 to 350 hp) hardware manual(3AXD50000044794 [English]).WARNING! Do not install a drive with the EMC filter connected to a systemthat the filter is not suitable for. This can cause danger, or damage the drive.Note: When the internal EMC filter is disconnected, the EMC compatibility of thedrive is considerably reduced. See section EMC compatibility and motor cable lengthin chapter Technical data in ACS580-01 (0.75 to 250 kW, 1.0 to 350 hp) hardwaremanual (3AXD50000044794 [English]). Ground-to-phase varistorA drive with the ground-to-phase varistor connected can be installed to asymmetrically grounded TN-S system. If you install the drive to another system, youmay need to disconnect the varistor. See section See section Checking thecompatibility with IT (ungrounded), corner-grounded delta, midpoint-grounded delta,and TT systems (for IEC) in ACS580-01 (0.75 to 250 kW, 1.0 to 350 hp) hardwaremanual (3AXD50000044794 [English]).WARNING! Do not install a drive with the ground-to-phase varistor connectedto a system that the varistor is not suitable for. If you do, the varistor circuit canbe damaged.
