Safety
Safety
WARNING! All electrical installation and maintenance work on the drive
should be carried out by qualified electricians only.
WARNING! The drive and adjoining equipment must be properly
grounded.
WARNING! Do not attempt any work on a powered drive. After
switching off the mains, always allow the intermediate circuit capacitors
5 minutes to discharge before working on the drive, the motor or the
motor cable. It is good practice to check (with a voltage indicating
instrument) that the drive is in fact discharged before beginning work.
WARNING! The motor cable terminals of the drive are at a dangerously
high voltage when mains power is applied, regardless of motor
operation.
WARNING! There can be dangerous voltages inside the drive from
external control circuits even when the drive mains power is shut off.
Exercise appropriate care when working on the unit. Neglecting these
instructions can cause physical injury or death.
Use of Warnings and Notes
There are two types of safety instructions throughout this manual:
• Notes draw attention to a particular condition or fact, or give
information on a subject.
• Warnings caution you about conditions which can result in serious
injury or death and/or damage to the equipment. They also tell you
how to avoid the danger. The warning symbols are used as follows:
Dangerous voltage warning warns of high voltage which can cause
physical injury and/or damage to the equipment.

• Warning stickers in several languages
• This manual
Mounting
WARNING! Follow the safety instructions given in this guide and in the
ACS550 or ACH550 User’s Manual.
To mount the OREL-01 module:
1. If not already off, remove mains power from the drive.
2. Remove the drive cover. (See instructions in the drive User’s Manual.)
3. Insert the OREL-01 module’s
plastic hooks into the front of
the drive at SLOT 1.
4. Carefully fit the connector at
the other end of the module
into the drive connector.
5. Press until the retaining clip
locks the module into position.
NOTE! Signal and power
connections to the drive are
automatically made through a
6-pin connector.
6. Non-English speaking
locations: Add a warning
sticker in the appropriate
language over the existing warning on the top of the module.

Installation
Wiring
Use 0.5 to 1.5 mm2(20 to 16 AWG) cable with an appropriate voltage
rating for digital signals.
1. Refer to “Terminal Designations” on page 6 and connect control wires
to the OREL-01 module.
Terminal Designations
Use the following table for reference when wiring terminals.
Replace Drive Cover
1. Refer to the drive’s User’s manual and replace the drive’s cover.
Apply Power
1. Turn on the mains power to the drive.
Note! When power is applied to the drive, the LED on the OREL
module should light.
2. Continue with the next section, Start-Up.

Start-Up
To configure the operation of the relays added using the OREL-01
module:
1. Power up the drive.
2. Use the control panel on the drive and set the parameters for relay
outputs 4 to 6 in Group 14 – Relay Outputs. Refer to the drive’s User’s
Manual for parameter descriptions, and for instruction on the control
panel operation.

Diagnostics
Diagnostics
Diagnostic LED
There is one diagnostic LED on the OREL-01 module. If the OREL-01
is properly installed, the green LED lights when the drive is powered up.
If the LED does not light within 5 seconds after power-up, there is no
communication with the drive.
Step down this column.
If an item is TRUE, look to
the RIGHT for suggestions.
Corrective Action
The module connection may
be damaged
Warning! Dangerous voltages are present
on the connector. Power down before
attempting to repair connector pins.
• Power down.
• Remove the module and check the condition of
the pins in the 6-pin connector.
• Reconnect and retest.
The module may have failed. Replace the module.
