Warning!
•
Never exceed the specified terminal torque on semiconductors and capacitors. Excessive force will
damage the part.
•
Use caution when inserting or extracting the gate leads on an IGBT. Excessive force can break or
stress the device.
•
Dropping the cell or lowering it too quickly could damage the unit and/or be harmful to personal
safety.
•
Be sure power plugs are properly aligned with the input/output bus before operating. Do not exceed
a 50 pound insertion force as this may damage the connectors. Never disconnect the cell while the
main is energized or while the cell is operating.
•
Always adhere to the recommended thermal compound and thickness. Excessive or inadequate
compound application may cause an insufficient thermal connection between base plate and heat
sink that may damage the cell.
•
Electrolytic capacitors are polarized. Installing a capacitor with the incorrect polarity will damage
the cell.
•
If cell sits idle for 6 months or more, the capacitor bank requires reforming. Failure to follow
reforming procedures and guidelines may result in cell damage.
•
The cell should be energized with a harmony transformer. The cell may be operated without a har-
mony transformer; however, it is important that the cell is pre-charged to at least 850vdc bus before
operating.
•
Never substitute with non-approved components; never parallel or series non-identical manufac-
turer's (or Siemens MDIT numbers) for IGBTs or capacitors in the same power cell.
•
Never use halogen type cleaning agents when cleaning a power cell. Use pressurized dry air, iso-
propyl alcohol, or water based solvent cleaning agents.
•
Always comply with local codes and requirements if disposal of failed components is necessary (for
example, control boards, capacitors, etc.). Some components may contain lead.
