* Customer may request IGBTs, diode rectifiers, and Cell Control Boards rather than a complete spare cell. Contact Siemens for further information regarding individual cell P/Ns.
Note: Unless notified differently by Siemens, ALWAYS replace components with the same P/N and revision level. |
4.4 Basic Rules for Repairing Harmony Cells
Cell failures or component failures should be reported to both the Quality Group and Product Development at Siemens.
Always refer to the latest BOM and Assembly Drawings for approved component Part Numbers and procedures when repairing any cell. Failure to use components other than those listed in the BOM may result in poor cell performance or further failures.
Warning! It is imperative to follow these rules for repairing Harmony Cells. |
1. Never parallel or series non-identical manufactures part numbers (or Siemens LD A MDIT Numbers) for IGBTs or Electrolytic Capacitors in the same power cell.
2. Never substitute a non-specified CCB/GCB/SMPS board (or any specified component or subassembly) without formal approval from the Product Development Group.
3. Never change an input power fuse(s) without first determining the root cause for the fuse operation. Fuses are not designed to protect components in the Power cell against overload. If a fuse(s) is open, there is
Maintenance GenIV Installation, Commissioning, and Maintenance Manual
usually a component failure within the cell. Re-application of rated power may cause catastrophic damage. Always inspect the related transformer winding and cell before replacing fuses.
Note: In cases where the latest BOM specifies obsolete components and the substitution of an alternative is not available, contact the Siemens LD A Product Development Group for assistance. In such events, Product Development may suggest alternative components, only after sufficient technical review and verification. |
Refer to Table 4-4 to view which fuses are approved for GenIV use:

4.4.1 How To Remove Harmony Power Cells
To Remove the Power Cell:
1. Power down the GenIV System, following the standard shut-down procedure shown in Section 1.4.
2. Open the doors to access the power cells.
3. Make sure that the DC bus LED (labeled “Charge LED” - see Section 1.4), located on the Cell Control Board (CCB), is off. Then wait an extra minute before proceeding.
4. Remove the fiber optic from the CCB as shown below.
5. Grab the two locking latches and pull down to a horizontal position to release the power cell.
Note: When the latches are pulled down to a horizontal position, the power cell will move forward approximately 1/2 inch. |

6. Still holding onto the latches, pull the power cell approximately one-third of the way out of its slot as shown next. Do not lift up or pull down on the cell, but rather let it slide on the polyethylene-coated mounting rails:

Note: It is good practice to not run the system with one of the cells removed. |
4.4.3 How to Install Harmony Power Cells
To Install the Power Cell:
1. Using the Siemens cell lifter (P/N A1A163496.08), line up the power cell with its slot.
2. Push the cell into its slot. Do not lift up on the cell, but instead let it slide in on the polyethylene-coated mounting rails.
3. Make make sure that the cell latches are above the ledge of the cell rail, and align the locking latches with the corresponding rail notches, as shown below:
