4.4.2 Example of AMF Wiring
4.4.3 Grounding
The shortest possible length of wire should be used for controller grounding. Use cable min. 2.5 mm

.
The negative "–" battery terminal must be properly grounded.
Switchboard and engine must be grounded at common point. Use the shortest possible cable to the
grounding point.
4.4.4 Power supply
To ensure proper function:
Use power supply cable min. 1.5 mm
2
Maximum continuous DC power supply voltage is 36 V. The controller’s power supply terminals are protected
against large pulse power disturbances. When there is a potential risk of the controller being subjected to
conditions outside its capabilities, an outside protection device should be used.
It is necessary to ensure that potential difference between generator current COM terminal and battery "–"
terminal is maximally ±2 V. Therefore it is strongly recommended to interconnect these two terminals
together.
Note:
The controller should be grounded properly in order to protect against lighting strikes. The maximum
allowable current through the controller's negative terminal is 4 A (this is dependent on binary output load).
