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
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.
Alternatives:
All digital inputs are from 115 or
230 V sources.
Digital inputs are from a mixture of
low voltage (10 to 24 VDC)
sources and high voltage (115 or
230 V) sources.
Installation
115/230 V Digital Input Module – OHDI-01
2
(20 to 16 AWG) cable with 24 V rating for connections
Situation
Wiring
Connect inputs according to the above
diagram. Use as many as required (up to 3
230V inputs or up to 6 115V inputs).
Route high voltage digital inputs through OHDI
module.
Route low voltage digital inputs directly to X1
on the drive.
