The hooks must be secured to the eyelets or upper lifting cubes. The chains must have all the same length. -
Page 22: Storage
5. STORAGE If the Megastation is not installed immediately, it should be stored in a dry place free from dust and corrosive pollutants. The storage site must be adequately ventilated, and heated if necessary without any extreme variations in temperature and condensation formation, and finally protected from moisture and weather. -
Page 23: Preliminary Operations
7.1 Checking the packaging When you receive the Megastation make sure that it has not been damaged externally and internally during transport. The integrity of the equipment and any packaging is checked up to loading on the transport mean when shipped from the Fimer factory. -
Page 24: Handling And Lifting
7.2 Handling and lifting Megastations are very heavy units; have handling operations carried out by qualified personnel. Check in advance the suitability and stability of the stands on which the unit will be placed. Do not store or transport the unit in a tilted position or placed on one side. The container must be raised as described below by the use of appropriate harness or a crane beam and using the points provided for this purpose. -
Page 25: Positioning
For proper positioning of the FIMER MEGASTATION a special base shall be prepared on which to rest the substation. -
Page 26: Checks Before Commissioning

Page 35: Appendix
APPENDIX INTRODUCTION The operation and maintenance of MEGASTATIONS have the aim to ensure high reliability (i.e., prompt identification of anomalies, failure prevention and functional monitoring) and safety. Maintenance means the set of interventions aimed to reduce degradation, to cope with accidental events and to renovate and / or replace parts inside the substation and the equipment mounted within that do not modify its performance substantially. - Page 36 The characteristics of the personnel executing electrical works not under voltage and in the vicinity just mentioned are as follows: SKILLED PERSON (PES): Trained person with relevant education and experience to enable him or her to avoid hazards which electricity could create. He/she has: ...
- Page 37 parts and secure any areas that may interfere with the working area (making disconnecting devices inaccessible, verifying the absence of voltage, shorting and earthing the disconnected part). He/she should inform workers about the safety measures and precautions to be taken. Even the execution of works under voltage must be under his/her control.
