SED2 VFD Startup, Operation, and Maintenance Manual

24 Siemens Building Technologies, Inc.

Input Power and Motor Connections

DANGER:

• Make certain that the motor rated full load amps (FLA)

does NOT exceed the rated output current of the SED2

controlling it.

When multiple motors are simultaneously operated by the

SED2, the sum of all motor rated FLA values must be

less than or equal to the SED2 controlling them.

• Never switch on the SED2 with it open.

• Always isolate the input power cables before connecting

them to the SED2.

• Always use insulated tools when working on input power

and motor terminals.

• Ensure that terminal covers are securely replaced after

connecting the input power and motor cables.

WARNING:

• Verify that the SED2 and motor are correctly rated for the

input power voltage.

• Verify that the input power cables are correctly sized for

the anticipated use.

• Confirm that appropriate circuit breakers or fuses have

been installed between the input power supply and the

SED2.

• Never use high-voltage insulation test equipment on any

cables connected to the SED2.
