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.

Installation 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 Grounding stand-off Panel port adapter Relay 2 Relay 3 Relay 4 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.
Installing the Module Delivery Check The option package contains: • MREL-01 module • 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.
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. Identification Hardware Description 1 COM OUTPUT RELAYS K2-K4: 2 NC 3 NO • Max. continuous current: 2 A rms (cos ϕ = 1), 1 A rms (cos ϕ = 0.4) 1 COM 2 NC 3 NO 1 COM 2 NC 3 NO K2 • Max.
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.
Technical Data Dimensions Module dimensions are shown in the figure below: Enclosure Degree of Protection IP20. Ambient Conditions The module is mounted outside the drive enclosure. Refer to the drive’s requirements.
• 6-pin connector (connection to the MMIO board) • Three 3-pin, screw-type, non-detachable terminal blocks that fit wires up to 1.5 mm2 (16 AWG). Specifications Module Specifications • Estimated min. lifetime: > 200,000 cycles/relay, at maximum continuous current operation. • All materials are UL/CSA-approved. • When used with an ABB drive, the module complies with EMC standard EN/IEC 61800-3 (2004) for electromagnetic compatibility and EN/IEC 61800-5-1 (2005) for safety requirements.
