What You Need to Do To install the PowerFlex
®
700L Frame 2 Power Module DC Bus Bar
Conversion Kit:
❐ Step 1: Remove power from the drive.
❐ Step 2: Remove the drive cover, inverter cassette, and vent cover.
❐ Step 3: Assemble the kit parts.
❐ Step 4: Reinstall the inverter cassette.
❐ Step 5: Document the change.
❐ Step 6: Reinstall the drive cover.
Step 1: Removing Power
from the Drive
1. Turn off and lock out input power. Wait 5 minutes.
2. Verify that there is no voltage at the drive’s input power terminals.
3. Remove the cover of the drive. Loosen the five (5) captive screws and
pull the cover off the drive. Set the cover aside to be reinstalled later.
!
ATTENTION: To avoid an electric shock hazard, verify that the
voltage on the bus capacitors has completely discharged before
performing any work on the drive. After removing power to the
drive, wait 5 minutes for the bus capacitors to discharge. Remove
the cover of the drive. Measure the DC bus voltage at the DC+
TESTPOINT and DC- TESTPOINT sockets on the front of the
drive (see drawing in Step 1.4). The voltage must be zero.
Remove power before making or breaking cable connections.
When you remove or insert a cable connector with power
applied, an electrical arc may occur, which can cause personal
injury or property damage by:
•
sending an erroneous signal to your system’s field devices,
causing unintended machine motion
•
causing an explosion in a hazardous environment
Electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create
electrical resistance.
