    The adjustable frequency drive must be protected against short circuit in order to avoid electrical or fire hazard. Danfoss recommends using the fuses mentioned in tables 4.3 and 4.4 in order to protect service personnel and equipment in case of an internal failure in the unit. The adjustable frequency drive provides full short circuit protection in case of a short circuit on the motor output.
  • Page 28 (symmetrical), 500 V / 600 V maximum. 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 adjustable frequency drive.
