Requirements For Ul/Cul/Csa - Siemens SINAMICS S120 Manual

4.2.2

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 45)".
● 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. The protection threshold is 115 % of the Power Module full load current.
When commissioning, you can adapt the motor overload protection using parameter
p0640.
● For frame size FSF, to connect line and motors only use 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.
● Only use copper cables rated for60 °C or 75 °C.
● For frame sizes FSE, only use cables that are certified for temperatures of 75 °C to
connect the braking resistor.
● The DC link terminals, DCP and DCN, were not investigated regarding conformance with
UL/cUL.
Additional requirements for CSA compliance:
Frame sizes FSA to FSC
Install the Power Module with an external interference 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 Power
– 480 V (phase with respect to ground), 480 V (phase to phase) for 400 V Power
● Terminal voltage, V
● Suitable for type 1 or type 2 SPD application (surge protective device)
Alternatively, use a Siemens surge protective device, Article number 5SD7424-1.
