Manual for Induction Motors and Generators2 - Safety Instructions 3BFP 000 050 R0101 REV EFollow the manufacturer's instructions when mounting or removing couplings or other driveelements and cover them with a touch guard. For trial run in uncoupled state, lock or remove theshaft end key. Avoid excessive radial and axial bearing loads (note manufacturer'sdocumentation). The balance of the machine is indicated as H = Half and F = Full key. In half-key cases, the coupling too, must be half-key balanced. In case of protruding, visible part of theshaft end key, establish mechanical balance.Make necessary ventilation and cooling system connections. The ventilation must not beobstructed and the exhaust air, also of neighbouring sets, not taken in directly.5. Electrical connectionAll operations must be carried out only by skilled persons on the machine at rest. Before startingwork, the following safety rules must be strictly applied:• De-energize!• Provide safeguard against reclosing!• Verify safe isolation from supply!• Connect to earth and short!• Cover or provide barriers against neighbouring live parts!• De-energize auxiliary circuits (for example, anti-condensation heating)!Exceeding of limit values of zone A in EN 60034-1 / DIN VDE 0530-1 - voltage ± 5%,frequency ± 2%, waveform and symmetry -leads to higher temperature rise and affects theelectromagnetic compatibility. Note rating plate markings and connection diagram in theterminal box.The connection must be made in a way that the permanent safe electrical connection ismaintained. Use appropriate cable terminals. Establish and maintain safe equipotential bonding.The clearances between uninsulated live parts and between such parts and earth must not bebelow the values of appropriate standards and values possibly given in manufacturer'sdocumentation.No presence of foreign bodies, dirt or moisture is allowed in the terminal box. Close unusedcable entrance holes and the box itself in a dust- and watertight manner. Lock the key when themachine is run without coupling. For machines with accessories, check satisfactory functioningof these before commissioning.The proper installation (for example, segregation of signal and power lines, screened cablesetc.) lies within the installer's responsibility.6. OperationVibration severity in the "satisfactory" range (Vrms ≤ 4.5 mm/s) according to ISO 3945 isacceptable in coupled-mode operation. In case of deviations from normal operation - forexample, elevated temperature, noises, vibrations - disconnect machine, if in doubt. Establishcause and consult manufacturer, if necessary.Do not defeat protective devices, not even in trial run. In case of heavy dirt deposits, cleancooling system at regular intervals. Open blocked condensate drain holes from time to time.Grease the bearings during commissioning before start-up. Regrease antifriction bearings whilethe machine is running. Follow instructions on lubrication plate. Use right kind of grease. In
