Wiring

Connect 115/230 VAC inputs to the OHDI high voltage side. Connect

the outputs from the OHDI low voltage side to the drive digital inputs.

For wiring, use:

• Appropriate voltage rated wiring (115 or 230 VAC) for the inputs to

the high voltage side.

• 0.5 to 1.5 mm

between the low voltage side and the drive terminals.

To determine the proper routing for wiring, refer to the following

sources:

• Either the "Terminal Designations – 115 VAC" section, or the

"Terminal Designations – 230 VAC" section below for the OHDI-01

module's terminal designations.

• The drive's terminal designations in the appropriate manual:

- ACS550 User's Manual

- ACH550 User's Manual

- ACS800 Hardware Manual

• The table below for alternatives.

• The diagram below for an overview of the connections.

• The illustrations below for a view of typical wiring connections.

Alternatives:

All digital inputs are from 115 or

230 VAC sources.

Digital inputs are from a mixture of

low voltage (24 VDC) sources and

high voltage (115 or 230 VAC)

sources.

115/230 VAC Digital Input Module – OHDI-01

(20 to 16 AWG) cable with 24 V rating for connections

Situation

Wiring

Connect inputs according to the diagram

below. Use as many as required (up to 3

230 VAC inputs or up to 6 115 VAC inputs).

Route high voltage digital inputs through OHDI

module.

Route low voltage digital inputs directly to X1

(on the ACS550/ACH550) or to X22 (on the

ACS800).
