Safety Rules and General Warnings
•Persons, who are not able to use the charger in a safe way, because of their physical, sensory or mental incompetence, or because of their
lack of experience, should not use without the control or instruction from a skilled or qualified person.
•The charger runs with 100-240 Volts alternating current, which is not suitable for children – Danger of Life. And beware of risk of electric shock
at all times.
•Avoid flammable gases, solvents or vapours all the time. Prevent open flame or sparks while charging in progress. Explosion RISK!
•Ensure sufficient air ventilation and prevent open flame or sparks while charging in progress.
•The charger is exclusively designed for charging rechargeable batteries and must not be used for other purposes. Corresponding model should
be selected for particular lithium-based or lead-based batteries.
•You should take into consideration of the charging instructions issued by the battery manufacturer before charging. Check also if the charge
profile fits your battery and application.
•DO NOT OPEN or DISMANTLE the charger. Repair work must only be processed by authorized technical staff.
•If the mains connection of the charger is damaged, it must be replaced with an original wire which is available at MEC or authorized dealers.
•NEVER place the charger on top of the battery while charging in progress.
•The charger should be protected against direct solar radiation or temperatures over 40°C.
•In case of obvious damage or malfunctioning, disconnect the charger from the mains supply and protect against unintended reconnection.
•The DC cable must not be cut, shortened or extended under any circumstances.
Special Features
•IP65 Passive cooling; extruded aluminium-alloy housing
•Microprocessor-based 4-Step charging technology with soft start and automatic re-start of the charge cycle
•5 Selectable battery types (GEL, AGM, WET, Calcium, +PS-Mode) and built-in battery temperature sensor for models targeting lead-based
batteries
•LED indicators showing corresponding charge status and errors
•Protection against short circuit, reverse polarity, over temperature or overload

Models Targeting Lead-based Batteries
Preparation –Before Charging
General Checking
•Check thoroughly the charger itself including all the cables show no damages
•Take into consideration the charging instruction issued by the battery manufacturer
Charging Cable – Polarity Checking
WARNING: Check the polarity before mounting onto a plug:
•Red cable = Plus (+)
•Black cable = Minus (-)
DC Mains Supply Checking
•Make sure the DC cable must not be cut, shortened or extended under any circumstances
•Make sure the mains supply complies with the technical specification requirements of the charger
Before Connecting the Charger to the Battery
•<For models targeting lead-acid batteries> First connect charger to the mains to select the appropriate loader, then disconnect from the
mains and connect the temperature sensor to the battery (the assembly depends on the battery manufacturer)
•<For all models> Make sure the charger is switched off and disconnected from the mains supply
•Then connect the terminals of the charger to the battery
•Finally connect the power cable of the charger to the mains supply, and switch on the charger
•The immobilizer core is switched to 0V when the charging process starts
For Models Targeting Lead-based Batteries
•Select the desired charge profile:
With proper connection, the LED of the currently active charge profile lights up continuously. To change the charge profile, press and hold the
"Press Button" for 5 seconds, the LED of the active profile will then change to slow flashing. Now you can switch between the different charge
profiles by briefly pressing the "Press Button". When the desired profile is selected, confirm the selection by pressing the "Press Button” again
for 5 seconds, the LED of the selected charge profile changes to steady lighting.
•Select the Power Supply Mode:
Follow the steps above to select a charge profile; the Power Supply Mode is signaled by the lighting up of all the 4 charge profile LEDs.
•The latest selected charge profile will be kept unless you change it
Charging the Battery
The charging process starts automatically and runs through the following stages:
Getting Ready: Auto Wake-up
Yellow Charge LED (4) and Green Full LED (3) are blinking alternately. During this pre-charge phase, the charger sends out series of controlled
current pulses to reactivate the BMS (if any) and bring in a voltage to the battery for getting ready for the charging process. If no battery or defected
battery pack is connected, the Red Error LED blinks. In this case, switch off the charger and check the battery pack.

Phase 1: Soft Start
Yellow Charge LED (4) keeps on lighting. The charger regulates the initial charging current to better prolong the battery life.
Phase 2: Constant Current Charging
Yellow Charge LED (4) blinks slowly. The battery is being charged to 80% of its capacity at this stage.
Phase 3: Constant Voltage Charging
Yellow Charge LED (4) blinks quickly. The battery is being charged to its maximum capacity. When the Green Full LED (3) turns on, the charger can
now be disconnected from the battery.
Phase 4: Float Charging (for lead-based batteries only) or Auto Restart
Green Full LED (3) keeps on lighting indicate the battery has reached its full capacity. If the battery keeps connecting to the charger, auto restart of
the charging cycle will take place after 7 days or when the battery voltage has dropped to under 3.6V/cell (Li-ion Battery) or 3.2V/cell (LiFePO4
Battery).
Disconnect the Charger from the Battery:
1. First, disconnect the charger from the mains supply
2. Then, disconnect the charger from the battery
After disconnecting the charger from the mains, please wait at least 5 seconds to reactivate the charger if in need – otherwise damages may be
resulted.
Charging Advice and Battery Care
Charging Advice:
•If the charger must be disconnected from the battery during the charging process, please FIRST disconnect the charger from the mains supply.
The continuation of the charging process is equal to a new charging cycle; all relevant points of the Operating Instructions have to be considered.
•To lengthen the lifetime of the battery, please do not stop the charging process before the battery is fully charged. The charger will automatically
stop when the charging process is completed.
Battery Care:
•Never expose the battery to high temperatures, as this causes permanent battery capacity loss.
•Never deep-discharge or overcharge the battery, cells can be damaged irreversibly.
•If possible, always disconnect the battery from the load when being stored over long period of time.
•Store battery in a dry and cool place at about 40-60% of its rated capacity.

Advice for Disposal
It is prohibited to dispose the charger with household or residual waste removal (WEEE-Richtlinie 2012/19/EU und
EAG-VO). The charger must be disposed at designated disposal points. For the protection of our environment, please
