● The integrated solid-state short-circuit protection does not provide branch circuit protection.
– UL: Branch circuit protection must be provided in accordance with the Manufacturer
Instructions, National Electrical Code and any additional local codes.
– CSA: Branch circuit protection must be provided in accordance with the Canadian
Electrical Code, Part I
● On the system side, provide branch circuit protection in conformance with NEC or CEC, Part
1, and the local regulations.
● The converters provide internal motor protection corresponding to UL61800-5-1. The
protection threshold is 115% of the converter full load current. When commissioning, you
can adapt the motor overload protection using parameter p0640.
● For frame sizes FSF and FSG, to connect the line supply and motor 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.
● The line and output voltage may not be lower than 400 V or higher than 600 V.
● Only use copper cables rated for 60 °C/75 °C. For converters FSA to FSC, only use copper
cables rated for 75 °C

When connecting a cable with a higher rated temperature, do not reduce the cable cross-
section.
Example: If a cable with a rated temperature of 60 °C is specified, the cable cross-section must
also be rated according to 60 °C. When connecting a cable with a higher rated temperature,
e. g. 90 °C, you must determine the cable cross-section as if the cable had a rated temperature
of 60 °C.
WARNING
Risk of explosion or spread of fire from built-in devices
Short circuits in the converter or its components may cause explosion or fire in the control
cabinet, which can result in serious personal injury or property damage.
● Install built-in devices in a suitable and robust metal cabinet in such a way that personnel
are protected against the explosive shock and fire, or take other appropriate protection
measures, for example, using five safety cabinet locks additionally.
Protection against the spread of fire
The device may be operated only in closed housings or in control cabinets with protective
covers that are closed, and when all of the protective devices are used. The installation of the
device in a metal control cabinet or the protection with another equivalent measure must
prevent the spread of fire and emissions outside the control cabinet.
Protection against condensation or electrically conductive contamination
Protect the device, e.g. by installing it in a control cabinet with degree of protection IP54
according to IEC 60529 or NEMA 12. Further measures may be necessary for particularly
critical operating conditions.
