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
2
(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).
