4. Setup and Installation

Proper installation is crucial for the reliable operation of the HSC940 controller. Refer to the wiring diagram (Figure 3.3) for all electrical connections.

4.1 Mounting the Controller

1. Prepare a panel cutout of 110mm x 90mm.
2. Insert the controller into the cutout from the front.
3. Secure the controller using the provided mounting clips from the rear of the panel.

4.2 Electrical Connections

Ensure all power is disconnected before making any electrical connections.

• DC Power Supply: Connect the DC power supply (8-35V) to the designated terminals.
• Genset AC Voltage: Connect the generator's AC voltage lines (U, V, W, N) to the corresponding terminals.
• Magnetic Pickup: Connect the magnetic pickup for engine speed sensing.
• Fuel and Crank Outputs: Connect the fuel solenoid and starter motor to the respective relay outputs.
• Auxiliary Inputs/Outputs: Connect any auxiliary sensors or actuators as required by your genset system.
• Communication (Optional): For remote communication, connect the SG485 module to the RS232/GSM terminals. For PC configuration, connect the SG72 module (USB to LINK).

Important: Double-check all wiring for correct polarity and secure connections to prevent damage to the controller or genset.
