Requirements for UL/cUL/CSA

Power Modules for plants and systems in the United States / Canada (UL/cUL)
● For a system configuration in conformance with UL/cUL, use the fuse types or circuit
breakers approved for UL/cUL specified in Chapter "Overcurrent protection using line
fuses and circuit breakers (Page 47)".
● 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 Power Module is equipped with internal motor overload protection corresponding to
UL 61800-5-1. 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
Power Modules. Please observe the details in the associated operating instructions.
● For frame sizes FSF and FSG, to connect the line supply and motors only use UL-
approved ring-type cable lugs (ZMVV), which are certified for the particular voltage, with a
permissible current of at least 125 % of the input and output current. Use the higher value
as basis.
● Carefully note that for plants and systems in conformance with UL/cUL, the line and
output voltage may not be higher than 600 V.
● FSA ... FSC: Only use copper cables rated for 75 °C.
● FSD ... FSG: Only use copper cables rated for60 °C or 75 °C.
● The Power Modules are open-type devices.
● Power Modules FSD ... FSF in a push-through version are open-type devices. Toward
the rear control cabinet panel, they comply with Enclosure Type 1.
