Ac Mains Connection; External Fan Supply (Unit Sizes 51 And 52); Knock-Outs (Unit Sizes 15, 21, 22, 31, And 32) - GE AF-600 FP Series Design And Installation Manual

Installation

2.5.4 AC Mains Connection

•
Size wiring based upon the input current of the
frequency converter.
•
Comply with local and national electrical codes
for cable sizes.
•
Connect 3-phase AC input power wiring to
terminals L1, L2, and L3.
•
Connect 1-phase AC input power wiring to
terminals L1 and L2. Only on single-phase rated
drives.
•
Input power will be connected to the mains input
terminals.
•
Ground the cable in accordance with grounding
instructions provided in 2.5.2 Earth (Grounding)
Requirements
•
All frequency converters may be used with an
isolated input source as well as with ground
reference power lines. When supplied from an
isolated mains source (IT mains or floating delta)
or TT/TN-S mains with a grounded leg (grounded
delta), set SP-50 RFI Filter to OFF. When off, the
internal RFI filtercapacitors between the chassis
and the intermediate circuit are isolated to avoid
damage to the intermediate circuit and to reduce
earth capacity currents in accordance with IEC
61800-3.
2.5.4.1 External Fan Supply (Unit Sizes 51
and 52)
In case the frequency converter is supplied by DC or if the
fan must run independently of the power supply, an
external power supply can be applied. The connection is
made on the power card.
Terminal No. Function
100, 101 Auxiliary supply S, T
102, 103 Internal supply S, T
Table 2.5
The connector located on the power card provides the
connection of line voltage for the cooling fans. The fans
are connected from factory to be supplied form a common
AC line (jumpers between 100-102 and 101-103). If external
supply is needed, the jumpers are removed and the supply
is connected to terminals 100 and 101. A 5 Amp fuse
should be used for protection. In UL applications this
should be LittleFuse KLK-5 or equivalent.
