11.2 Fuses

A distinction is made between protecting the power supply cables and protecting the de-
vice. To fulfill CE specifications – here in particular EN 60204-1 – fuse the power supply
cables.
NOTE!
Approved, UL-listed safety fuses must be used in UL-authorized systems, refer to
ZUL notes–
Cable protection Use safety fuses of the operating class gL VDE 0636-201 / DIN EN 60269-2-1 / HD
630.2.1 54 or circuit breaker triggering characteristic K, in accordance with VDE 0636-201
/ DIN EN 60269-2-1 / HD 630.2.1 54, to protect the cable. These fuses protect against
overloads and consequential damage from defects, for example as a result of fire. How-
ever, they cannot prevent a device from being extensively destroyed in case of a short-
circuit or ground fault in the DC link.
Carry out the fusing in accordance with EN 60204-1 („Electrical Equipment of Machines").
Dimension the cable fuse based on the cross-section of the power supply cable used, and
in accordance with the respective applicable national standards and local regulations.
The current-carrying capacity of the cables is specified in Table 5 of EN 60204-1. For your
application, the corresponding value must still be determined based on the standard itself,
i. e. taking into account the cable routing.
NOTE!
Use suitable fuses with the tripping characteristic gL or gR.
NOTE!
The BM50XX is protected in case of overload because the device limits the output
current. This can be considered when dimensioning the cable protection fuses.
