Warning
1.The installation of this equipment must be carried out by professionals.
2.When installing and operating the controller, please read the entire instruction
manual first.
3.Any maintenance and commissioning of the equipment must be familiar with all the
equipmen
4.t, safety standards and precautions in advance, otherwise it may cause personal
injury or damage to related equipment.
5.The engine must have an overspeed protection device independent of the
controller system to avoid casualties or other damage caused by engine out of
control.
6.After the installation of the controller is completed, please verify that all protection
functions are valid.
Be Care
1.Please keep the good connection of the power supply of the controller. Do not
share the connection lines of the positive and negative electrodes of the battery
with the floating charger.
2.During the operation of the engine, do not disconnect the battery,otherwise it may

Installation instruction
The controller should be installed by four accessories and screw.
Panel Cutout：W78mm*H66mm.
78
66
Note: If the controller is installed directly in the genset shell or other fluctuated
equipment, the rubber pad must be installed.
Battery Voltage Input
DC30D controller is suitable for 98-18 VDC battery voltage. Battery negative must be
reliably connected to the enclosure of the engine. The controller power supply B+
and B- must be connected to battery positive and negative, and the wire size must
not be less then 1.5mm2.
NOTE:
In case of floating charger connect charger output to battery positive and negative
directly, then, connect battery positive and negative poles to controller positive and
negative power supply
AC current input
Current transformer with rated secondary current 62.5mA must be externally
connected to the controller current input.
WARNING:When generator is on-load, C. T. secondary must not be open
circuit, Otherwise, the high voltage generated will pose a danger to personal safety.
Withstanding voltage test
If withstanding voltage test is conducted after the controller has already been
installed onto the control panel, please unplug all controller terminal connections in
order to prevent high voltage from damaging it.
