Appendix B PowerFlex 7000 Drive Spare Part Storage Requirements and Recommendations
SGCT/SCR/SPS
Energize with nominal input voltage for 1…2 hours every year of storage.
To energize these components:
SGCT
• Use the AC power source, PS1, and IGDPS power supplies to power up
the SGCT boards.
• Alternatively, use a variable DC source with current limiting
functionality and the IGDPS power supplies.
• Or, use the assembly of variable AC power source (120V or 240V), SPS,
and SPS wire harness that are provided with the drive.
SPGDB
• Use a variable DC power source with current limiting functionality.
SPS
• Use an assembly of variable AC power source (120V or 240V) and
provided with the drive SPS wire harness.
If the boards were not energized for longer than 3 years, perform the following
reconditioning procedures:
•SGCT
- Apply 20V DC voltage (from an IGDPS or a variable DC power source)
through a current limiting resistor (around 300 Ohms/1 Watt
minimum) for one hour.
•SPGDB
- Apply 20V DC voltage (from an IGDPS or a variable DC power source)
through a current limiting resistor (around 300 Ohms/1 Watt
minimum) for a period of one hour.
Cooling Fans
Rotated by hand (10…20 spins) every 3 months to ensure circulation of
lubricant in bearings and to help prevent brinelling of the bearings.
Signal Conditioners
These components have a 3 year lifetime storage period.
