Recommendations - GE AF-650 GP Operating Instructions Manual

Installation
3.4.10 Fuses
It is recommended to use fuses and/ or circuit breakers on the supply side as protection in case of component break-down
inside the drive (first fault).
NOTE
This is mandatory in order to ensure compliance with IEC 60364 for CE or NEC 2009 for UL.
WARNING
Personnel and property must be protected against the consequence of component break-down internally in the drive.
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 protected against short-circuit and over-current according to national/international regulations.
NOTE
The recommendations given do not cover Branch circuit protection for UL.
Short-circuit protection:
GE recommends using the fuses/Circuit Breakers mentioned below to protect service personnel and property in case of
component break-down in the drive.
Over current protection:
The drive provides overload protection to limit threats to human life, property damage and to avoid fire hazard due to
overheating of the cables in the installation. The drive is equipped with an internal over current protection (F-43 Current
Limit) that can be used for upstream overload protection (UL-applications excluded). Moreover, fuses or Circuit Breakers can
be used to provide the over current protection in the installation. Over current protection must always be carried out
according to national regulations.

3.4.11 Recommendations

WARNING
In case of malfunction, not following the recommendation may result in personnel risk and damage to the drive and other
equipment.
The following tables list the recommended rated current. Recommended fuses are of the type gG for small to medium
power sizes. For larger powers, aR fuses are recommended. Circuit breakers must be used provided they meet the national/
international regulations and they limit the energy into the drive to an equal or lower level than the compliant circuit
breakers.
If fuses/Circuit Breakers according to recommendations are chosen, possible damages on the drive will mainly be limited to
damages inside the unit.
