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.

Installation

Preparing for Installation

The OREL-01 Module

The Relay Output Extension module (OREL) is an interface for

connecting three relay outputs to an ACS550 or ACH550 drive.

Module Layout

Compatibility

The OREL-01 is compatible with all ACS550 and ACH550 drives.

The option package contains:

• OREL-01 module

• 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

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.
