4.8 Protection :
●
Output current limited.
●
MCCB tripped in case of over current of
main input.
●
MCCB tripped in case of reverse polarity
connection of battery.
5. INSTALLATION PLACE
5.1 Avoid humid places.
5.2 Avoid environment of corrosive gas.
5.3 Do not expose it to direct sun radiation or close
a heating source.
5.4 Install it in a place that is easily accessible,
adequate ventilation and without vibrations.
5.5 Batteries generate explosive hydrogen gas,
even during normal operation.
5.6 People may injure by battery parts flying in an
explosion.
5.7 They can explode under normal operating
conditions.
5.8 Avoid Flames and Sparks Near Battery.
6. WIRING AND ADJUSTMENT
6.1 Ensure the output of the battery charger is
accords with the voltage of battery.
6.2 Ensure the wiring of the battery charger is
accords with main input voltage.
6.2.1 Main Voltage is 110VAC. (Figure 3)
●
Main power feed in 1 and 2.
●
Connect 3 and 4 with jumper wire.
●
Connect 5 and 6 with jumper wire.
6.2.2 Main Voltage is 220VAC.
●
Main power feed in 1 and 2.
●
Connect 4 and 5 with jumper wire.
●
Terminal 3 and 6 are null.
6.2.3 Connect main power.
●
Turn power MCCB on.
●
The power pilot LED and float charge LED
should illuminated.
●
Voltmeter should appear default value 13.8V
(at 12V system) or 27.8V (at 24V system).
6.3 If procedure 6.2 is performed normal turn
power MCCB off.
Connect the output of this unit to the post of
battery carefully.
CAUTION
Terminal lug must properly and securely
crimp onto wires.
Because of the high current being carried by
these lugs.
An inadequate or improper crimp will
eventually lead to overheating of the joint.
Failure will soon follow, often with severe
damage spreading beyond the immediate
crimp joint.
6.4 Turn power MCCB on again.
Adjust 10 to expected value.
NOTE
The value must refer to the battery user’s
guide.
Over charge current will cause batteries
damaged and this is helpless to shorten
charge time.
6.5 Factory default setting voltage are.
●
CH1812 Equalize charge mode is 14.5VDC.
Float charge mode is 13.8VDC.
●
CH1824 Equalize charge mode is 28.8VDC.
Float charge mode is 27.8VDC.
●
Unless the target battery is very old do not
change the default value.
6.6 Charge current is limited in the preset value
anytime in spite of the target batteries was fully
discharged.
The value will decrease accompanies the
battery is charged. The value approach to zero
represent the battery is nearly saturation.
6.7 Float charge mode is effective at initial power
on.
●
In case of the battery is extremely discharged
or repeat charge is needed press button 6
the equalize charge mode is effective.
●
Equalize charge mode will continue to
6/12/24 hours and back to float charge mode
automatically to prevent battery overcharged.
Factory default time is 6 hours. (Figure 2)
●
Turn the power MCCB off is able to break
equalize charge mode.
