12 INSTALLATION

12.1 FIXING CLIPS

The module is held into the panel fascia using the supplied fixing clips.
1) Withdraw the fixing clip screw (turn anticlockwise) until it reaches proper position.
2) Pull the fixing clip backwards (towards the back of the module) ensuring four clips are inside their
allotted slots.
3) Turn the fixing clip screws clockwise until they make contact with the panel.
Note: Care should be taken not to over tighten the screws of fixing clips.

12.2 OVERALL DIMENSION AND Panel CUTOUT

1) Battery Voltage Input
HGM400N series controller can suit for widely range of battery voltage DC(8~35)V. Negative of
battery must be connected with the engine shell. The diameter of wire from power supply to battery
must be over 2.5mm
battery's positive and negative directly, then, connect wires from battery's positive and negative to
controller's positive and negative input ports in order to prevent charge disturbing the controller's
normal working.
2) Speed Sensor Input
Speed sensor is the magnetic equipment which be installed in starter and for detecting flywheel
teeth. Its connection wires to controller should apply for 2 cores shielding line. The shielding layer
should connect to No. 1 terminal in controller while another side is hanging in air. The else two
signal wires are connected to No.1 and No.17 terminals in controller. The output voltage of speed
sensor should be within AC(1~24)V (effective value) during the full speed. AC12V is recommended
(in rated speed). When install the speed sensor, let the sensor is spun to contacting flywheel first,
then, port out 1/3 lap, and lock the nuts of sensor at last.
3) Output And Expansion Relay
All outputs of controller are relay contact output type. If need to expand the relays, please add
freewheel diode to both ends of expand relay's coils (when coils of relay has DC current) or, add
