11 INSTALLATION
11.1 FIXING CLIPS
— Withdraw the fixing clip screw (turn anticlockwise) until it reaches proper position.
— Pull the fixing clip backwards (towards the back of the module) ensuring four clips are inside their
allotted slots.
— Turn the fixing clip screws clockwise until they are fixed to the panel.
— Care should be taken not to over tighten the screws of fixing clips.
NOTE: A torque of 0.27N·m (2.75kgf·cm) is recommended
11.2 OVERALL DIMENSION AND PANEL CUTOUT
Fig.5– Overall Dimensions and Panel Cutout (Unit: mm)
HFC6110LT controller can be applicable to (8~35) VDC battery voltage. Battery negative must be
reliably connected to ground. The connection between controller power B+/B- and positive /negative of
battery should not be less than 1.5mm

. If a float charger is fitted, please connect output line of the
charger with battery directly, and then connect battery positive and negative to power input of controller
separately, in case that charger will interfere with the normal running of controller.
— Output and expansion relay: all the outputs of controller are transistor output. If need to expand
relay, please add freewheeling diode in both ends of relay coil (when expansion relay coil links DC),
or add RC loop (when expansion relay coil links AC), in case controller or other equipment are
interfered.
— Dielectric strength test: when the controller has been installed in the control panel, during the test
please disconnect all the terminals, in case high voltage damages the controller.
