SED2 Variable Frequency Drives
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.
Review the Installation & Startup Guide (125-3201) and the O&M Manual (125-3202). Review
( ) 2.
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
IMPORTANT: Double check all power wires (L1(r), L2(s), L3(t)) and motor wires (T1(u), T2(v),
( ) 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
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.
