1. Important Safety Instructions
General Safety Precaution:
A. Do not expose the charger to rain, snow, spray, or bilge water. To reduce risk
of fire hazard, do not cover or obstruct the ventilation openings. Do not install
the charger in a zero-clearance compartment. Overheating may result.
B. The charger is designed to be permanently connected to your AC and DC
electrical systems.
C. Never use chargers at a location where there is danger of gas or dust explosions.
Before installing and using the charger, read all instructions and cautionary
markings on the charger, the batteries, and all appropriate sections of this guide.
D. Use only attachments recommended or sold by the manufacturer. Doing otherwise
may result in a risk of fire, electric shock, or injury to persons.
E.
Do not disassemble the charger. Attempting to service the unit yourself may result
in a risk of electrical shock or fire. Internal capacitors remain charged after all
power is disconnected.
F.
The charger must be provided with an equipment-grounding conductor connected
to the AC input ground.
G. To reduce the risk of electrical shock, disconnect both AC and DC power from
the charger before attempting any maintenance or cleaning or working on
any circuits connected to the charger. Turning off controls will not reduce this
risk.
H.
Do not operate the charger if it has received a sharp blow, been dropped,
or otherwise damaged in any way.
I.
To avoid a risk of fire and electric shock, make sure that existing wiring is in
good condition and that wire is not undersized. Do not operate the charger
with damaged or substandard wiring.

2. Installation Location:
Physical requirements for installation
Condition Description
The unit is intended for use in a dry location. Do not allow water
or other fluids to drip or splash on the charger. Do not mount
the charger in an area subject to rain, spray or splashing bilge
water.
Do not expose the charger to metal filings or any other form
of conductive contamination. The presence of conductive
contamination can cause damage and void your warranty.
For best performance, the ambient air temperature should be
between 5°F (-15°C) and 113°F (45°C)- the cooler the better.
At higher ambient temperatures, the output current will be
automatically reduced to protect the charger from high internal
temperatures.
Dry
Clean
Cool
Ventilated
Allow at least 4 inches (10 cm) of clearance around all sides
of the charger for air flow. Ensure that the ventilation openings
on the unit are not obstructed. If mounting in a compartment,
ventilate the compartment with louvres or cut-outs to prevent
overheating.
Close to AC
junction box
Avoid the use of extended wire lengths if possible.
Close to
batteries
Avoid excessive cable lengths and use the recommended
wire lengths and sizes. Undersized or overly long cables may
affect charging accuracy.
Safe
Working in the vicinity of lead-acid batteries is dangerous.
Batteries generate explosive gases during normal operation.
It is safest not to install electrical equipment in these areas.

IMPORTANT
This product is best mounted in a Horizontal position.
If the unit is mounted in a vertical position,
The cooling fan must be at the bottom of the unit.

How to instal?
 
C . Isolated Design
The DC battery charging circuits of this charger are galvanically isolated
by a transformer from the AC power circuits. This feature reduces the risk
of electric shock .

① With the frame only, if there’s the hole on the wall for phone jack.
②
With the frame and rear both, if the user just can screw the bracket on the
wall, no hole for phone jack.
or
When the battery (-) pole temp. reaches 65°C (+/-5°C) / 149°F (+/-41°F), the charger
would stop output.

(1). The chargers have been approved as Ignition Protected. They may be installed
in areas containing gasoline tanks and fittings which require Ignition Protected
equipment. It is safest not to install electrical equipment in these areas.
WARNING
Explosive gases; Prevent flames and sparks; Provide adequate ventilation during
charging. Include a warning against recharging non-rechargeable batteries.
If the supply cord is damaged, it must be replaced by a special cord or assembly
available from the manufacturer or its service agent.

7.Charging Formula
( A ) . Charging Time
Formula
Example
Charging time will depend on the capacity of your battery and on how
deeply it is discharged. The following equation calculates an approximate
charging time.
Charging time =
where:
Charging Time: Battery recharge time in hours
CAP:
Battery capacity in amp-hours
DOD: Battery depth of discharge in per cent. A fully
discharged battery has 100% DOD
CC:
Charge current, the rated current output of the
charger in amperes
80%:
Typical charging efficiency forlead-acid batteries
A Group size battery rated at 100 amp-hours is 40% discharged, that is,
it has a DOD = 40. Charging time with a C-15L-12 unit is
calculated as follows:
Charging time = = 3.3 hours
CC x 80%
15A x 80%
100Ah x 40%
CAP x DOD
( B ) . Discharging Time
To achieve 50% cycling you should calculate your Amp-hour consumption between
charging cycles and use a battery bank with twice that capacity. To calculate Amp hour
consumption, first look at the rating plate on your AC appliance or tools.
Each appliance or tool will be rated in either AC Amps or AC watts or AC VA(Volts-Amps)
apparent power.
Use one of the following to calculate the DC Amp-hour draw for a 12 Volt system:
(AC Amps x 10) x 1.1 x hours of operation = DC Amp-hours
(AC watts/12) x 1.1 x hours of operation = DC Amp-hours
(AC VA/12) x 1.1 x hours of operation = DC Amp-hours
In all formulas, 1.1 is the factor for inverter/charger efficiency.
Calculate the above for every AC appliance or tool you intend to use on your inverter.
This will give you the total number of Amp-hours used between recharges. Size your battery
bank using this number as a guideline. A good rule to follow is to size the battery bank about
2 times larger than your total Amp-hour load requirement. Plan on recharging when 50% discharged.
Many electric motors have momentary starting requirements well above their operational rating.
Start up watts are listed where appropriate. Individual styles and brands of appliances may vary.
NOTICE: Lead-acid battery is recommended for inverter/charger models, also the LiFePO4 battery.
