•
Wiring diagrams are examples. Use the application's wiring diagram during installation.
•
Genset and mains contactor latching relays should be compiled against 4 kV surge as per IEC-61000-4-5 standard.
•
Relay cards used with the controller should be protected against reverse battery voltages.
•
Analogue input 2 used for Fuel level sensor can be wired with the reference to Battery Negative, see Specifications,
Analogue resistive sensor inputs.
•
Communication ports for CAN ( terminals 58 and 59) and RS-485 (terminals 31 and 32) have built-in 120 Ω termination
