SECTION2:INSTALLATIONANDOPERATION
2.1 Make sure that the correct battery charger is
selected for your battery.
2.2 Check correct line power for the battery charger.
2.3 Connect line voltage to the charger, then the
“ power indicator ” should be lit up and display will
show the output voltage and current, the DC
output voltage be as follow :
CH3612：13.8 Vdc +/- 1%
CH3624：27.6 Vdc +/- 1%
2.4 AC power off before connect the charger DC
output to battery leads “+ & -”.
Caution!! Crimp and property secure terminal
lugs on to power wires to avoid shorts.
2.5 Turn on AC power, battery charger will charge the
battery with an automatic adjusted current related
to battery voltage and cyclically displays charging
voltage and current on screen.
2.6 Floating charge mode with current-limiting function
built-in. Charger can remains connected during
engine cranking heavy load condition.
2.7 For CH3612, minimum battery voltage must higher
than 6 Vdc or the battery charger will automatically
shut-down and all the indicators on the panel will
be went out. ( For CH3624, the minimum battery
voltage is 12 Vdc ).
2.8 Voltage sensing circuit automatically stops
charging battery when the battery is fully charged.
2.9 Input and output connection cable size ≧
1.25mm² (AWG 16).
SECTION 3 : LOW DC VOLTAGE ALARM
For CH3612 when battery volt less than 10 Vdc
For CH3624 when battery volt less than 20 Vdc
“ Low DC indicator ” will be lit up with solid state 0.5A
battery negative alarm output.

SECTION 5 : DANGER
5.1 Charger has been completely tested and
calibrated precisely, Potentially lethal voltages are
present inside. Do not open case and attempt to
adjust or repair this unit.
5.2 Ventilate battery enclosure, batteries generate
explosive hydrogen gas.
5.3 Always avoid flames and sparks near batteries,
avoid high humid or corrosive gases.
5.4 In case of detaching charger, turn the line power
off first.
5.5 This is not a power supply. Use only as a battery
charger.
5.6 Build-in AC power input protect fuse, no external
fuse is needed. Do not attempt to replace it when
blew.
