Safety instructions 15Additional instructions for permanent magnet motor drives Safety in installation, start-up and maintenanceThese are additional warnings concerning permanent magnet motor drives. The othersafety instructions in this chapter are also valid.WARNING! Obey these instructions. If you ignore them, injury or death andequipment malfunction can occur.• Do not do work on the drive when the permanent magnet motor is rotating. Arotating permanent magnet motor energizes the drive including its input powerterminals.Before installation, start-up and maintenance work on the drive:• Stop the motor.• Disconnect the motor from the drive with a safety switch or by other means.• If you cannot disconnect the motor, make sure that the motor cannot rotate duringwork. Make sure that no other system, like hydraulic crawling drives, can rotatethe motor directly or through any mechanical connection like felt, nip, rope, etc.• Measure that the installation is de-energized.- Use a multimeter with an impedance of at least 1 Mohm.- Make sure that the voltage between the drive output terminals (T1/U, T2/V,T3/W) and the grounding (PE) busbar is close to 0 V.- Make sure that the voltage between the drive input power terminals (L1, L2,L3) and the grounding (PE) busbar is close to 0 V.- Make sure that the voltage between the drive module UDC+ and UDC-terminals and the grounding (PE) busbar is close to 0 V.• Install temporary grounding to the drive output terminals (T1/U, T2/V, T3/W).Connect the output terminals together as well as to the PE.Start-up and operation:• Make sure that the operator cannot run the motor over the rated speed. Motoroverspeed causes overvoltage can damage or explode the capacitors in theintermediate circuit of the drive.
