Branch circuit protection
In order to protect the installation against electrical and fire
hazard, all branch circuits in an installation, switch gear, ma-
chines etc., must be short-circuit and over-current protected
according to the national/international regulations. Please refer
to
section 8.0
(Fuse and wire recommendation).
Short circuit protection
The inverter must be protected against short-circuit to avoid
electrical or fire hazard. The frequency converter provides full
short circuit protection in case of a short-circuit on the motor
output.
