Wiring Overview

Conduit/Gland Kit

Wiring drives with the IP 21 / UL type 1 Enclosure requires a conduit/gland kit with
the following items:
• Conduit/gland box
• Five (5) cable clamps (ACS550-01 only)
• Screws
• Cover
The kit is included with IP 21 / UL type 1 Enclosures.

Wiring Requirements

Warning! Ensure the motor is compatible for use with the ACS550. The
ACS550 must be installed by a competent person in accordance with the
considerations defined in "Preparing for Installation" on page 8. 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 (IP 21 / UL type and IP 54 / 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 "Motor Cable Requirements for CE & C-Tick Compliance" on page 226. In
general:
– Follow local codes for cable size.
– Keep these four classes of wiring separated: input power wiring, motor wiring,
• When installing input power and motor wiring, refer to the following, as
appropriate:
Terminal
U1, V1, W1*
PE
U2, V2, W2
* The ACS550 -x1-xxxx-2 (208...240V series) can be used with a single phase supply, if output
current is derated by 50%. For single phase supply voltage, connect power at U1 and W1.
• To locate input power and motor connection terminals, see "Power Connection
Diagrams" starting on page 15. For specifications on power terminals, see
"Drive's Power Connection Terminals" on page 223.
• For frame sizes R1...R4 in unsymmetrically grounded networks, see
"Unsymmetrically Grounded Networks" on page 221.
• For floating (or impedance grounded) networks, see "Floating Networks" on page
222.
