66 Electrical installation Motor and motor cable1. Check that the motor cable is disconnected from the drive output terminals U2, V2 andW2.2. Measure the insulation resistance between each phase conductor and then betweeneach phase conductor and the Protective Earth conductor using a measuring voltageof 1000 V DC. The insulation resistance of an ABB motor must exceed 100 Mohm(reference value at 25 °C or 77 °F). For the insulation resistance of other motors,consult the manufacturer’s instructions. Note: Moisture inside the motor casing willreduce the insulation resistance. If moisture is suspected, dry the motor and repeat themeasurement.Attaching the device stickers on the cabinet doorA multilingual device label sticker is delivered with the drive. Attach the stickers in the locallanguage on the English texts, see section Door switches and lights on page 31.ohmM3~U1V1W1 PEohm
