Electrical Installation
5.1.3 Fuses
Branch circuit protection
In order to protect the installation against electrical and fire hazard, all branch circuits in an installation, switch gear,
machines etc., must be shortcircuit and overcurrent protected according to the national/international regulations.
Short circuit protection
The frequency converter must be protected against short-circuit to avoid electrical or fire hazard. Danfoss recommends
using the fuses mentioned in tables 4.3 and 4.4 to protect service personnel or other equipment in case of an internal
failure in the unit. The frequency converter provides full short circuit protection in case of a short-circuit on the motor
output.
5 5
Over-current protection
Provide overload protection to avoid fire hazard due to overheating of the cables in the installation. Over current protection
must always be carried out according to national regulations. The frequency converter is equipped with an internal over
current protection that can be used for upstream overload protection (UL-applications excluded). See ADAP-KOOL
AKD102 Programming Guide, par. 4-18. Fuses must be designed for protection in a circuit capable of supplying a maximum
of 100,000 A
rms
Non UL compliance
If UL/cUL is not to be complied with, Danfoss recommends using the fuses mentioned in table 4.2, which will ensure
compliance with EN50178:
In case of malfunction, not following the recommendation may result in unnecessary damage to the frequency converter.
