• If you are not a qualified electrician, do not do electrical installation or maintenancework.• Do not install the drive if the electrical power network, motor/generator, or environmentalconditions do not agree with the drive data.• Do not install a drive with EMC filter (option +E200 or +E202) on an ungrounded powersystem or a high resistance-grounded (over 30 ohms) power system.• We do not recommend that you secure the cabinet by arc welding. If you have to, obeythe separate welding instructions in the drive manuals.• Do not do insulation or voltage withstand tests on the drive.Note:• The motor cable terminals of the drive are at a dangerous voltage when the input poweris on, regardless of whether the motor is running or not.• When the input power is on, the drive DC bus is at a dangerous voltage. If brake chopperand resistor are in use, they are also at a dangerous voltage. (Option +D150)• External wiring can supply dangerous voltages to the relay outputs of the control unitsof the drive.• The Safe torque off function does not remove the voltage from the main and auxiliarycircuits. The function is not effective against deliberate sabotage or misuse.WARNING!Obey these instructions. If you ignore them, damage to the equipment can occur.• Handle fiber optic cables with care:• When you unplug the cables, always hold the connector, not the cable itself.• Do not touch the ends of the fibers with bare hands as the ends are extremelysensitive to dirt.• Do not bend the fiber optic cables too tightly. The minimum allowed bend radius is35 mm (1.4”).WARNING!Use a grounding wrist band when you handle printed circuit boards. Do not touchthe boards unnecessarily. The boards contain components sensitive to electrostaticdischarge.￭ GroundingThese instructions are for all personnel who are responsible for the grounding of the drive.WARNING!Obey these instructions. If you ignore them, injury or death, or equipmentmalfunction can occur, and electromagnetic interference can increase.• If you are not a qualified electrician, do not do grounding work.• Always ground the drive, the motor and adjoining equipment. This is necessary for thepersonnel safety. Proper grounding also reduces electromagnetic emission andinterference.• Make sure that the conductivity of the grounding conductors is sufficient. See electricalplanning instructions. Obey the local regulations.20 Safety instructions
