Check Step
( ) 1. The SED2 is thoroughly tested at the factory. Verify that the drive is free of shipping and
installation damage. Shipping damage is not covered by the Siemens Industry, Inc. warranty;
claims must be filed directly with the shipping company as soon as possible.
( ) 2. Review the Installation & Startup Guide (125-3201) and the O&M Manual (125-3202). Review
option instructions and schematics shipped with the drive.
( ) 3. Verify that the model numbers and the voltage ratings are as specified in the purchase order by
matching the nameplate data for each unit to the purchase order.
( ) 4. Verify that the drive has been installed in accordance with the mechanical and electrical
installation sections in the O&M Manual.
CAUTION:
Failure to comply with mechanical and electrical installation requirements may void the product
warranty.
( ) 5. Verify that the 50/60 Hz DIP switch has been set to the appropriate setting, as instructed in the
Installation & Startup Guide.
( ) 6. Inspect the security of the supply line power, ground connections, and all control circuit
connections as identified in the SED2 documents.
IMPORTANT: Confirm that the incoming line power supply connects to the drive input terminals
(L1(r), L2(s), L3(t)) and NOT to the output motor terminals (T1(u), T2(v), T3(w)).
IMPORTANT: Double check all power wires (L1(r), L2(s), L3(t)) and motor wires (T1(u), T2(v),
T3(w)) to make sure that they are securely tightened down to their respective
lugs. Loose wire connections may cause problems at any time, and are not
covered under warranty.
( ) 7. Review the installer’s “as wired” schematic. Determine where the motor “safety circuit” is
connected. Verify that the customer’s emergency contacts are properly terminated in the drive’s
safety shutdown circuit or bypass panel.
Verify that all other field-installed wires are correctly terminated (including the shields).
( ) 8. Record the motor(s) nameplate information:
Voltage: ____________________ Service Factor: _________________________________
Full Load Amps (FLA): _________________ RPM: _________________________________
Efficiency: _________________ Horsepower (HP): _________________________________
( ) 9. Verify that the input voltage matches the drive’s rating.
( ) 10. Verify that the motor is wired for the application voltage.
( ) 11. IMPORTANT: Verify that the motor rated full load amps (FLA) does NOT exceed the rated
output current of the drive controlling it.
When multiple motors are simultaneously operated by the drive, the sum of all motor rated FLA
values must be less than or equal to that of the drive controlling them.
( ) 12. Record any other connections to the drive by terminal number to determine if special
programming is required.
Note any changes in Appendix: Parameter Settings.
( ) 13. If applicable, verify that the building automation system logic is ready to perform adequately for
start, stop, and speed command functions.
This concludes the preparation process for SED2 VFD startup.
Keep your Installation & Startup Guide, O&M Manual, option schematics, and any other instructions sent with the
drive easily accessible to assist you through the remainder of this startup process.

HVAC Startup
Procedure for SED2
with Conventional
Bypass Option
Review the Preparing for SED2 VFD Startup section in this document.
Use the following HVAC startup procedure for SED2 VFDs with the Bypass Option. For
startup of SED2 VFDs without the Bypass Option, see the HVAC Startup Procedure for
SED2 without Bypass Option section in this document.
Check Step
( ) 1. Verify that the electrical supply power lines connect to the input device and that the motor leads
connect to the output terminals of the overload relay. Ensure that all connections are tight; factory
connections may come loose during shipment. Set the thermal mechanical overload for the
bypass panel to the motor’s FLA.
( ) 2. Record all other connections to the bypass cabinet or the VFD and confirm (if applicable) that the
building management system logic is ready to perform adequately for start, stop, and speed
command functions.
( ) 3. Before applying power, make sure that the following conditions are met:
•The DRIVE/OFF/BYPASS switch is OFF.
•For units with three contactors, the Drive Test ON/OFF switch is OFF.
( ) 4. Apply power to the drive and bypass package. Make sure that all three phases are present and
that the input voltage is correct for the system being set up. Then move the DRIVE/OFF/BYPASS
switch to the DRIVE position.
At this time, if the display indicates a fault, press to reset it.
( ) 5. Verify that the drive display is on.
( ) 6. Press to access Parameter r0000 and to enter the SED2 programming mode. From here, you
can access and change Level 1 parameters using or .
Repeatedly press to advance to Parameter P0010. Press to access the parameter values
level.
Press to advance to 1. Press to confirm and save the P0010=1 setting. The Quick
Commissioning procedure starts. See the Quick Commissioning Procedure section in this
document for details.
On completion of the Quick Commissioning procedure, continue with Step 7.
( ) 7. Press and then to return to the drive operating mode.
( ) 8. To start the Drive, press and then (green start key). The drive will ramp up to “10 HZ”.
Verify that the direction of motor rotation is correct.
NOTE: If the direction of motor rotation is wrong, turn the DRIVE/OFF/BYPASS switch to OFF;
and turn Power Off! Wait for 5 minutes.
Swap wires on the motor terminals (T1(u), T2(v)) or on the output terminals of the
motor overload relay. Tighten the terminal lugs, reapply power, turn
DRIVE/OFF/BYPASS switch to DRIVE; and recheck the direction of motor rotation.

( ) 9. With correct motor rotation, manually run the drive throughout its entire operating range while
observing operation.
•If the drive trips on over-current during acceleration adjust the acceleration time rate via
Parameter P1120.
•If the drive trips on over-voltage during deceleration, adjust the deceleration time rate via
Parameter P1121.
•If excessive vibration of the driven load is noted at specific input frequencies, use Skip
Frequency Parameters P1091 through P1094 to eliminate this vibration.
( ) 10. Determine whether the remote speed reference is a 0 to 10 Vdc or a 4 to 20 mA signal. Connect
signal wires and place analog input DIP Switch in the appropriate position.
( ) 11. Check the signal for proper polarity. Observe if the remote speed command can achieve the
minimum and maximum speeds desired. If not, scale as required.
( ) 12. Set the DRIVE/OFF/BYPASS switch to OFF. When the drive is in the run mode, it will coast to a
stop.
For units with three contactors, set the Drive Test ON/OFF switch to ON. Verify that the drive
input contactor energizes.
( ) 13. Make additional drive application parameter settings as required, and record them in
Appendix: Parameter Settings.
( ) 14. BYPASS TEST—Be prepared to monitor rotation of the motor in bypass operation.
“Bump” the DRIVE/OFF/BYPASS switch to BYPASS and then quickly back to OFF. Check the
motor rotation.
CAUTION:
Do NOT allow the motor to operate in bypass mode unless the motor rotation is correct.
( ) 15. If motor rotation in bypass mode is correct, skip to the next step.
If motor rotation in bypass mode is NOT correct, check the following and perform as described:
•Turn OFF the incoming power feed to the drive. Since the correct rotation in drive mode was
previously established, do not change any output wires at motor.
•Instead, verify that power to the input device is OFF. Swap L1 and L2 on the input side of the
circuit breaker/disconnect switch. This will affect rotation in the bypass operation only. Once
connections are complete and tight, reapply incoming power and repeat Step 14 to recheck
the rotation direction.
( ) 16. Verify that running at full speed will NOT damage the system.
Run the motor in bypass by turning the DRIVE/OFF/BYPASS switch to BYPASS.
Record all the phase voltages and currents at this time.
AC input voltage: Phase A____________Phase B ___________ Phase C _____________
AC output voltage: Phase A___________Phase B ___________ Phase C _____________
Output Current: Phase A ____________ Phase B ___________ Phase C _____________
Display Current: _______________Software Version: _________________________
( ) 17. Turn the DRIVE/OFF/BYPASS switch to DRIVE and set panel to auto start/stop. Check speed
references from application specific devices for appropriate operation.
This completes the startup procedure for the SED2 VFD with Conventional Bypass Option.
