10.7.7 Removing the Power Cell Procedure
Power Cell Removal
CONTACT SIEMENS for PROPER Cell lifter information.
• Refer to the "VFD Power Down and Door Access" chapter, section "Unlocking the Doors", prior
to removing power cells. Be sure to obey all standard electrical and safety instructions.
DANGER
Lethal Voltages
Even when the system is powered down, power may still be present at the power cell's DC
bus. The recommended waiting time before opening the doors or removing covers is
10 minutes.
DANGER
Lethal Voltages
The cell should not be touched, removed, or serviced if the indicator is illuminated.The cell
chassis is not grounded and when energized can oat to lethal voltages. Failure to install
proper grounding connections may result in death or cause damage to the drive.
• Use appropriate Personal Protective Equipment (PPE). Be sure not to touch any bare bus bars
while removing the power cell.
CAUTION
Existing Voltage May Still Be Present
An LED that is not extinguished indicates that power is present.
The power cells include discharge resistors to dissipate stored energy after the input voltage
is removed. The power cell DC bus voltage decays to less than 50 VDC in less than 10 minutes
