12 INSTALLATION

12.1 FIXING CLIPS

— The controller is panel-embedded design and it is fixed by clips in installation.
— Twist the fixing clip screw anticlockwise until it reaches proper position.
— Pull the fixing clip backwards (towards the back of the module), ensuring two clips are right
inside their allotted slots.
— Turn the fixing clip screws firmly clockwise until they are fixed on the panel.
NOTE: Pay attention not to over tighten the clip screws.

12.2 OVERALL AND CUTOUT DIMENSIONS

— Battery Voltage Input
MGC300 controller is only suitable for DC(8~35)V battery voltage environment. Battery negative
must be connected with the engine shell soundly. The diameter of the wire which connects controller
power B+/B- and battery positive/negative must be over (or equal to) 1.5mm
configured, please firstly connect charger output wires to battery's positive and negative directly, and then
connect battery's positive and negative and controller power's positive and negative individually with
separated wires in order to prevent charger disturbing the controller's normal working.
— Output and Expand Relays
All outputs are relay contactor outputs. If relay expansion is needed, please add flyback diode
(expansion relay coil has DC) to the two ends of expansion relay coils, or add resistance-capacity circuit
(expansion relay coil has AC), in order to prevent distuibing controller or other devices.
— AC Current Input
MGC300 controller current input must connect outside CT. CT secondary side rated current must be
62.5mA, and at the same time CT phase and input voltage phase must be correct, otherwise the current
sampling and active power may be incorrect.
WARNING: When there is load current, CT secondary side open circuit is strictly prohibited.
— Withstand Voltage Test
When the controller has been installed in the control panel, if the high voltage test is conducted,
please disconnect controller's all terminals in order to prevent high voltage entering controller and
damaging it.
