Start-Up - Siemens SED2 VFD NEMA Operating Instructions Manual

( ) 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:
Full Load Amps (FLA): ______________________ RPM: _________________________
( ) 9.
( ) 10.
( ) 11.
IMPORTANT:
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 bypass controlling them.
Individual motor protection per local code is provided.
( ) 12.
programming is required.
( ) 13.
adequately for start, stop, and speed command functions.
This concludes the preparation process for SED2 startup.

Verify that the input voltage matches the drive's rating.
Verify that the motor is wired for the application voltage.
Verify that the motor rated full load amps (FLA) does NOT exceed
the rated output current of the drive controlling it.
Record any other connections to the drive by terminal number to determine if special
If applicable, verify that the building automation system logic is ready to perform
CAUTION:
1. A heater is supplied with all outdoor enclosures to minimize the effects
of condensation. The heater is only powered when the main power to
the enclosure is on. If the unit has been de-energized for any period,
inspect for and rectify any condensation in the enclosure before
reapplying power.
2. The heater should be set above the typical average dew point for your
part of the country. If unsure of your typical dew point temperature, 75°F
(24°C) should be appropriate for most areas.
