Installation in the United States and Canada (UL or CSA)
Measures for a UL and cUL‑compliant installation:
● Use the specified overcurrent protection device.
● A multi-motor drive is not permissible, i.e. simultaneously operating several motors
connected to one inverter.
● The integrated semiconductor short-circuit protection in the inverter 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 inverter, use the following power and motor cables:
– FSAA with rated power ≤ 1.5 kW: Copper conductor, suitable for temperatures ≤60 °C
– FSAA (2.2 KW) and FSA … FSC: Copper conductor, suitable for temperatures ≤75 °C
– FSD … FSF: Copper conductor, suitable for temperatures ≤60 °C or ≤75 °C
● For frame size FSE, use a copper conductor suitable for temperatures ≤75 °C 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 certified 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 inverter 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 fulfilled according to UL 508C and UL 61800‑5‑1.
