Safety instructions83ADW000462R0101 DCS880 Hardware Manual e aInstallation and maintenance workThese warnings are intended for all who work on the drive, motor cable or motor.Ignoring the instructions can cause physical injury or death and/or damage to theequipment.WARNING- Only qualified electricians are allowed to install and maintain the drive!- Never work on the drive, motor cable or motor when main power is applied.Always ensure by measuring with a multimeter (impedance at least 1 Mohm)that:1. Voltage between drive input phases U1, V1 and W1 and the frame isclose to 0 V.2. Voltage between terminals C+ and D- and the frame is close to 0 V.- Do not work on the control cables when power is applied to the drive or to theexternal control circuits. Externally supplied control circuits may causedangerous voltages inside the drive even when the main power on the drive isswitched off.- Do not make any insulation resistance or voltage withstand tests on the drive ordrive modules.- Isolate the motor cables from the drive when testing the insulation resistance orvoltage withstand of the cables or the motor.- When reconnecting the motor cable, always check that the C+ and D- cablesare connected with the proper terminal.Note:- The motor cable terminals on the drive are at a dangerously high voltage whenthe main power is on, regardless of whether the motor is running or not.- Depending on the external wiring, dangerous voltages (115 V, 220 V or 230 V)may be present on the relay outputs of the drive system (e.g. XRO1 ... XRO3).- DCS880 with enclosure extension: Before working on the drive, isolate thewhole drive from the supply.
