INSTALLATION
Controller is panel built-in design and it is fixed by clips when installed. The controller overall dimensions
and cutout size are as below:
Fig. 10 Case Dimensions and Cutout
13.1 BATTERY VOLTAGE INPUT
HGM8156 controller suits wide range battery voltage (8~35)VDC. Negative of battery must be
connected with the shell of starter. The wire diameter of connecting B+ and B- with battery negative and
positive must not be less than 2.5mm
2
. If floating charger is installed, please firstly connect output wires
of charger to battery’s positive and negative directly, then connect wires from battery’s positive and
negative to controller power input terminals in order to prevent charger
disturbing the controller’s normal
working.
13.2 OUTPUT AND EXPAND RELAYS
CAUTION!
All outputs of controller are relay contact outputs. If it needs to expand relays, please add freewheel diode
to both ends of expansion relay coils (when coils of relay has DC current) or, increase resistance-capacitance return
circuit (when coils of relay has AC current), in order to prevent disturbance to controller or other equipments.
13.3 AC INPUT
Current input must be connected to outside current transformer. Curren
t transformer’s secondary side
current must be 5A. At the same time, phases of current transformer and input voltage must be correct,
otherwise collected current and active power may not be correct.
NOTE:
ICOM port must be connected to negative of battery.
WARNING!
When there is load current, transformer’s secondary side is prohibitted to open circuit.
13.4 WITHSTAND VOLTAGE TEST
CAUTION!
When controller has been installed in control panel, if high voltage test is needed, please disconnect
controller’s all terminal connections, in order to prevent high voltage entering controller and damaging it.
