Saff ety (1 Sa (1/2 /2)) Only qualified electricians are allowed to maintain m aintain the drive. The ACS550-01/U1 frame sizes R1…R4 are not field repaired units. Never attempt to repair a malfunctioning unit; contact the factory or your local Authorized Service Center for replacement. Never work on the drive, motor cable or motor when input power is applied. After disconnecting the input power, always wait for 5 minutes to let the intermediate circuit capacitors c apacitors discharge before you start working on the drive, motor or motor cable. Always ensure by measuring with a multimeter that: 1. There is no voltage between drive input phases U1, V1 and W1 and the frame. . B B A 2 1 3 0 2 / . 1 d 1 / e 0 v r 1 e t s h e g r i r s y t p h g o i r C l
2. There is no voltage between terminals UDC+ and UDC-, or BRK+ and BRK-.
Saff ety (2 Sa (2/2 /2)) Even when power is removed from the input terminals of the ACS550, there may may be dangerous voltage (from external sources) on the terminals of the relay outputs R01 to R03. Do not make any insulation or voltage withstand tests on the drive. The motor cable terminals on the drive are at a dangerously high voltage when the input power is on, regardless of whether the motor is running or not. Even when the motor is stopped, dangerous voltage is present at the power circuit terminals U1, V1, W1 and U2, V2, W2 and, depending on the frame size, UDC+ and UDC-, or BRK+ and BRK-. .
