NOTE!
UNIT SIZE 6X REQUIREMENTS
An equal amount of wires to each inverter module is
required. The cables must be of equal length within 10%
between inverter and first common point in a phase
(recommended at motor terminal)
2.5.4 AC Line Power Connection
•
Size wiring based upon the input current of the
adjustable frequency drive.
•
Comply with local and national electrical codes
for cable sizes.
•
Connect 3-phase AC input power wiring to
terminals L1, L2, and L3.
•
Input power will be connected to the line power
input terminals.
•
Ground the cable in accordance with grounding
instructions provided in
•
All adjustable frequency drives may be used with
an isolated input source as well as with ground
reference power lines. When supplied from an
isolated line power source (IT line or floating
delta) or TT/TN-S power line with a grounded leg
(grounded delta), set
SP-50 RFI Filter to OFF. When
off, the internal RFI filter capacitors between the
chassis and the intermediate circuit are isolated
to avoid damage to the intermediate circuit and
to reduce ground capacity currents in accordance
with IEC 61800-3.
2.5.4.1 External Fan Supply (Unit Sizes 41,
42, 43, 44, 51, and 52)
If the adjustable frequency drive 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
102, 103
Auxiliary supply S, T
Internal supply S, T
Table 2.3
The connector located on the power card provides the AC
line voltage connection for the cooling fans. The fans are
factory-equipped to be supplied from a common AC line
(jumpers between 100-102 and 101-103). If an 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 a LittleFuse KLK-5 or equivalent.
