The is more than a maintenance document—it is the single source of truth for electrical troubleshooting, modification, and safety compliance. Without it, a simple loose wire can escalate into a week of downtime.
For actual physical wiring, you cannot rely on a generic diagram. Each machine has a unique electrical schematic that corresponds to its specific configuration of options and features.
The controller module itself typically receives its operating power from a dedicated control transformer, stepping down the main line voltage to 24V AC or 115V/230V AC depending on the regional configuration.
The digital blueprint blossomed across the screen. He traced his finger along the —the nervous system that allowed the Mk5 to speak to the sensors. “You’re not talking,” he muttered, his eyes darting between the screen and the physical 1X1 and 1X2 terminal strips.
The MK5 base unit does not run on 400V. However, the diagram shows voltage presence at contractor terminals. The 400V lines are isolated from the low-voltage controller. The diagram uses thick lines for high voltage and thin lines for 24V. atlas copco elektronikon mk5 wiring diagram full

Incorrect wiring can cause immediate equipment damage, void warranties, and create serious safety hazards. The voltage-free output contacts on the MK5 are specifically not to be used for safety-related circuits . Always follow the safety precautions and guidelines in your machine's official documentation.
The Elektronikon Mk5 is built for modern industrial automation. The bottom or rear of the module features dedicated communication ports: The is more than a maintenance document—it is
If you need specific diagrams for different compressor models or gateway setups, these technical documents provide detailed schematics: GA18-30 VSD+ Service Diagram: Includes a detailed Electrical Service Diagram for Mk5S variants. EKO75-kW VST Diagram: Provides a 75kW Variable Speed Motor diagram with full MK5 control circuit details. Gateway Module Guide: For networking and remote control, the Mk5 Gateway Manual outlines Modbus and Profibus pin-layouts. General Wiring Guide: Elektronikon Wiring Guide covers equipment components and display menus.
Shielded loops carry 4–20 mA or 0–10V signals from pressure and temperature sensors to prevent electromagnetic interference (EMI) from distorting the readings. Terminal Block Configurations and Layout
Air pressure (transmitter), compressor element temperature. Outputs (DO): Loading solenoid, fan motor relay. C. Motor Start/Stop Circuit
: An optional component often integrated into the power circuit to protect the motor from reverse rotation. 2. Controller I/O Terminals Each machine has a unique electrical schematic that
The standard physical port configuration for plant integration. It requires a twisted, shielded pair wire topology with proper end-of-line termination resistors (typically 120 ohms) to prevent signal reflection over long distances.
The MK5 digital output (e.g., DO1 on connector CON2, pin 6) sends a 24V DC signal to the coil of K1. The return path goes through the overload relay’s normally closed (NC) auxiliary contact (terminals 95-96).
A "full" wiring diagram is not just a simple line drawing; it is a comprehensive map of every wire, terminal, relay, and electronic component inside the compressor’s control panel. Without it, troubleshooting becomes guesswork, leading to costly downtime.
: Requires a specific bridge module that acts as a proxy for the compressors on the network.
