Tightening torque for reassembly is 1.35 N•m (12 lb•in). We
recommend replacing all capacitors at the same time.
5. Repeat
for each remaining DC bus capacitor being
removed.
Install the Power Structure DC Bus Capacitors
Install the capacitors in reverse order of removal. Make sure to observe the
polarity of the capacitors as noted in removal
, above.
Replace the Existing Power Structure with a New Power Structure
To replace the power structure, follow these steps.
1. Remove the old power structure from the enclosure.
Remove the Power Structure from the Enclosure on page 52
2. Remove the common mode capacitors from the new Frame 10 power
structure that is replacing the old power structure.
For the procedure to remove the common mode capacitors, see the
PowerFlex Active Front End User Manual, publication
.
See Chapter 2, section ‘Disconnect Common Mode Capacitors’, and
subsection ‘Frame 10 Power Structure’. These instructions apply to an
AFE in an IP20 2500 MCC Style enclosure or an AFE in an IP21 Rittal
enclosure.
3. Install the new (replacement) power structure.
Install the Power Structure in the Enclosure on page 55
IMPORTANT
When replacing the power structure with a new power structure, you must
remove the common mode capacitors in the new power structure to avoid
possible equipment malfunction.
