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.

Preparing for Installation
The MREL-01 Module
The Relay Output Extension module (MREL) is an interface for
connecting three relay outputs to an ACS310 or ACS350 drive.
Module Layout
Compatibility
MREL-01 is mechanically compatible with all ACS310 and
ACS350 drives.
MREL-01 is supported by all ACS310 software versions and
ACS350 software and hardware versions from 258A.

• Grounding stand-off
• Panel port adapter
• Warning stickers in several languages
• This manual
Mounting
WARNING! Follow the safety instructions given in this guide and
in the ACS310 or ACS350 User’s Manual.
To mount the MREL-01 module:
1. If not already off, remove mains power from the drive.
2. Remove the control panel or panel cover. (See instructions in the
drive User’s Manual.)
3. Remove the grounding screw in the top left corner of the drive’s
control panel slot and install the grounding stand-off in its place.
4. Ensure that the panel port adapter is attached to either the panel
port of the drive or the mate part of the MREL-01 module.
5. Gently and firmly install the MREL-01 module to the drive’s panel
slot directly from the front.
NOTE! Signal and power connections to the drive are
automatically made through a 6-pin connector.
6. Ground the module by inserting the screw removed from the drive
in the top left corner of the MREL-01 module. Tighten the screw.

Installation
NOTE! Correct insertion and tightening of the screw is essential
for fulfilling the EMC requirements and proper operation of the
module.
7. Install the control panel or panel cover on the MREL-01 module.

Wiring
• Use 0.5 to 1.5 mm2(20 to 16 AWG) cable with an appropriate
voltage rating for digital signals.
• Refer to “Terminal Designations” on page 9 and connect control
wires to the MREL-01 module.
Terminal Designations
Use the following table for reference when wiring terminals.
Apply Power
1. Turn on the mains power to the drive.
2. Continue to the next section, Start-Up.

Start-Up
Start-Up
To configure the operation of the relays added using the MREL-01
module:
1. Power up the drive.
2. In ACS350, set the parameter 9801 EXTENSION SEL to 2
(MREL). See the User’s Manual of the drive for more information
on parameters.
3. Use the control panel on the drive and set the parameters for relay
outputs 2 to 4 in Group 14 – Relay Outputs. Refer to the User’s
Manual of the drive for parameter descriptions, and for instruction
on the control panel operation.
