10.5 Fuses and Circuit Breakers
Fuses ensure that possible damage to the drive is limited to damages inside the drive. To ensure compliance with EN 50178,
use the recommended fuses as replacements. Use of fuses on the supply side is mandatory for IEC 60364 (EC) and NEC 2009
(UL) compliant installations.
Branch circuit protection
To protect the installation against electrical and re hazard, all branch circuits in an installation, such as those branch circuits
found in switchgear and machines, must be protected against short circuit and overcurrent according to national/interna-
tional regulations.
Fuses or circuit breakers are mandatory to comply with IEC 60364.
