6Installation and maint<strong>en</strong>ance workThese warnings are int<strong>en</strong>ded for all who work on the drive, motor cable or motor.WARNING! Ignoring the following instructions can cause physical injury or death, ordamage to the equipm<strong>en</strong>t:• Only qualified electricians are allowed to install and maintain the drive.• Never work on the drive, the motor cable or the motor wh<strong>en</strong> main power isapplied. After switching off the input power, always wait for 5 min to let theintermediate circuit capacitors discharge before you start working on the drive,the motor or the motor cable.Always <strong>en</strong>sure by measuring with a multimeter (impedance at least 1 Mohm)that:1. voltage betwe<strong>en</strong> drive input phases U1, V1 and W1 and the frame is close to0V2. voltage betwe<strong>en</strong> terminals UDC+ and UDC- and the frame is close to 0 V.• Do not work on the control cables wh<strong>en</strong> power is applied to the drive or to theexternal control circuits. Externally supplied control circuits may causedangerous voltages inside the drive ev<strong>en</strong> wh<strong>en</strong> the main power on the drive isswitched off.• Do not make any insulation or voltage withstand tests on the drive or drivemodules.• Wh<strong>en</strong> reconnecting the motor cable, always check that the phase order iscorrect.Note:• The motor cable terminals on the drive are at a dangerously high voltage wh<strong>en</strong>the input power is on, regardless of whether the motor is running or not.• The brake control terminals (UDC+, UDC-, R+ and R- terminals) carry adangerous DC voltage (over 500 V).• Dep<strong>en</strong>ding on the external wiring, dangerous voltages (115 V, 220 V or 230 V)may be pres<strong>en</strong>t on the terminals of relay outputs RO1 to RO3 or on the optionalAGPS board (Prev<strong>en</strong>tion of Unexpected Start).• The Prev<strong>en</strong>tion of Unexpected Start function does not remove the voltage fromthe main and auxiliary circuits.• At installation sites above 2000 m (6562 ft), the terminals of the RMIO boardand optional modules attached to the board do not fulfil the Protective ExtraLow Voltage (PELV) requirem<strong>en</strong>ts stated in EN 50178.Safety instructions
