3.4.4 AC Line Power Connection
•
Size wiring based upon the input current of the
drive. For maximum wire sizes, see Table 10.1.
•
Comply with local and national electrical codes
for cable sizes.
•
Connect 3-phase AC input power wiring to
terminals L1, L2, and L3 (see Illustration 3.7).
•
Depending on the configuration of the
equipment, input power will be connected to the
line power input terminals or the input
disconnect.
•
Ground the cable in accordance with grounding
instructions provided in 3.4.2 Grounding
Requirements
•
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 14-50 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.

Isolate control wiring from high power
components in the adjustable frequency drive.
If the adjustable frequency drive is connected to
a thermistor, for PELV isolation, optional
thermistor control wiring must be reinforced/
double insulated. A 24 VDC supply voltage is
recommended.
Remove access coverplate with a screwdriver. See
Illustration 3.8.
Or remove front cover by loosening attaching
screws. See Illustration 3.9.
Tightening torque for front cover is 2.0Nm for
unit size 15 and 2.2Nm for unit sizes 2X and 3X.
