Wiring requirements
WARNING! Ensure the motor is compatible for use with the ACS550. The drive must
be installed by a competent person in accordance with the considerations defined in
section Preparing for installation on page 12. If in doubt, contact your local ABB
sales or service office.
As you install the wiring, observe the following:
There are four sets of wiring instructions – one set for each combination of drive
enclosure type (IP21 / UL type and IP54 / UL type 12) and wiring type (conduit or
cable). Be sure to select the appropriate procedure.
Determine electro-magnetic compliance (EMC) requirements per local codes.
See section Motor cable requirements for CE & C-Tick compliance on page 287.
In general:
Follow local codes for cable size.
Keep these four classes of wiring separated: input power wiring, motor wiring,
control/communications wiring and braking unit wiring.
When installing input power and motor wiring, refer to the following, as
appropriate:
To locate input power and motor connection terminals, see section Power
connection diagrams on page 21. For specifications on power terminals, see
section Drive’s power connection terminals on page 280.
For corner grounded TN systems, see section Corner grounded TN systems on
page 279.
