Converters for systems in the United States / Canada (UL/cUL)
● For a system configuration in conformance with UL/cUL, use the fuse types approved for
UL/cUL, specified in the Technical data, or the circuit breakers under the following
Internet address.

● The integrated semiconductor short-circuit protection does not provide cable protection.
● On the system side, provide
cable protection in conformance with NEC or CEC, Part 1
and the local regulations.
● The converters provide internal motor protection corresponding to UL61800-5-1.
Protection threshold:
– 115% of the rated motor current entered for frame sizes FSA … FSF
– 120% of the rated motor current entered for frame size FSG
You enter the motor data values and the protection functions when commissioning the
converter. Please observe the details in the associated operating instructions.
● Use suitable UL-listed (ZMVV) ring lugs to connect the power terminals of frame sizes
FSF and FSG.
● Carefully note that for plants and systems in conformance with UL/cUL, the line and
output voltage may not be higher than 600 V.
● Only use copper cables rated for 60 °C or 75 °C.
● FSE, IP20: Only use cables that are certified for temperatures of 75 °C to connect the
braking resistor.
● FSE, PT: Only use cables that are certified for temperatures of 75 °C to connect the line
supply, motor and braking resistor.
● The converters are Open Type devices.
● The push-through FSD ... FSF converters are Open Type devices. At the rear of the
control cabinet they fulfil Enclosure Type 1.
Additional requirements for CSA compliance, frame sizes FSA … FSC
Install the converter with an external suppression device with the following properties:
● Surge protection device with the appropriate certification (category checking numbers
VZCA and VZCA7)
● Rated supply voltage
– 240 V (phase with respect to ground), 240 V (phase to phase) for 200 V converters
– 480 V (phase to phase) for 400 V converters
