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 274 .
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 20 . For specifications on power terminals, see
section Drive’s power connection terminals on page 268 .
• For corner grounded TN systems, see section Corner grounded TN systems on
page 267 .
