Protective devices for SINAMICS G120C (https://support.industry.siemens.com/cs/ww/en/

Installation in the United States and Canada (UL or CSA)
Measures for a UL and cUL‑compliant installation:
• Use the speci󹪝ed overcurrent protection device.
• A multi-motor drive is not permissible, i.e. simultaneously operating several motors
connected to one converter.
• The integrated semiconductor short-circuit protection in the converter does not provide
branch protection. Install branch protection in compliance with the National Electric Code or
the Canadian Electrical Code, part 1 and also all local regulations.
• Depending on the converter, use the following power and motor cables:
– FSAA with rated power ≤ 1.5 kW: Copper cable with a nominal temperature value of 60° C
1)
– FSAA (2.2 KW) and FSA … FSC: Copper cable with a nominal temperature value of 75° C
1)
– FSD…FSF: Copper cable with a nominal temperature value of 60°C/75°C
1)
For frame size FSE, use copper cables suitable for temperatures ≤ 75° C
1)
for connecting the
braking resistor.
• For frame size FSF, to connect the line supply and motor, only use UL approved ring-type
cable lugs (ZMVV), which are certi󹪝ed for the particular voltage. Permissible current of the
ring-type cable lugs ≥ 125 % of the input or output current.
• Leave parameter p0610 in its factory setting.
The factory setting p0610=12 means: The converter responds to motor overtemperature
immediately with an alarm and after a certain time with a fault.
• When commissioning the drive system, set the motor overload protection to115%, 230%
or 400% of the rated motor current using parameter p0640. As a consequence, the motor
overload protection is ful󹪝lled according to UL508C and UL61800‑5‑1.
1)
When connecting a cable with a higher nominal temperature value, it is not permissible
that you reduce the cable cross-section.
Example: If a cable with a nominal temperature value of 60°C is speci󹪝ed, then the cable
cross-section must also be dimensioned according to 60°C. When connecting a cable with a
higher nominal temperature value, e.g. 90°C, you must dimension the cable cross-section as
if the cable had a nominal temperature value of 60°C.
