6 115/230 V Digital Input Module – OHDI-01
Installation
Wiring
Connect 115/230V inputs to the OHDI inputs and connect OHDI 24V
outputs to the drive digital inputs.
For wiring, use:
• Appropriate voltage rated wiring (115 or 230 V) for the inputs to the
high side.
• 0.5 to 1.5 mm
2
(20 to 16 AWG) cable with 24 V rating for connections
between the low side and the drive terminals.
To determine the proper routing for wiring, refer to the following
sources:
• The "Terminal Designations" 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.

Situation Wiring
All digital inputs are from 115 or
230 V sources. Connect inputs according to the above
diagram. Use as many as required (up to 3
230V inputs or up to 6 115V inputs).
Digital inputs are from a mixture of
low voltage (10 to 24 VDC)
sources and high voltage (115 or
230 V) sources. Route high voltage digital inputs through OHDI
module.
Route low voltage digital inputs directly to X1
on the drive.
