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.
•Ensure sufficient air ventilation; do not cover the vent outlet while charging in progress.
•Avoid flammable gases, solvents or vapours all the time. Prevent open flame or sparks while charging in progress. Explosion RISK!
•The charger is exclusively designed for charging Rechargeable Lead-based Batteries and must not be used for other purposes.
•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.
•Keep the charger in dry room (rel. humidity <80%). Clean with dry cloth only. Avoid fluid of any kind to get into the charger.

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
•Make sure the charger is switched off and disconnected from the mains supply
•Then connect the terminals of the charger to the battery (Red cable to the positive (+) terminal of the battery; then Black cable to the negative
(-) terminal)
•If the battery is built-in within a vehicle, the Black cable can be connected to the negative (-) terminal of the battery or the body of the vehicle;
make sure the connection is done with a safe distance from the fuel line and take into consideration of the battery and vehicle manufacturer
•Finally connect the power cable of the charger to the mains supply, and switch on the charger
Charging the Battery
Plug in and switch on the charger. The charging process starts automatically and runs through the following stages:
Phase 1: Constant Current Charging
Red Charge LED (7) blinks or lights up. The battery is being charged to 80% of its capacity at this stage.
Phase 2: Constant Voltage Charging
Yellow Charge LED (6) blinks or lights up. The battery is being charged to its maximum capacity. When the Green Full LED (5) turns on, the charger
can now be disconnected from the battery.
Phase 3: Float Charging
Green Full LED (5) keeps on lighting indicate the battery has reached its full capacity. If the battery keeps connecting to the charger, float charge
mode takes place to keep the readiness of the battery at all time.
Disconnect the Charger from the Battery:
1. First, disconnect the charger from the mains supply
2. Then, disconnect the charger from the battery (disconnect the Black (-) cable first then the Red (+) cable)
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
switch to float charging 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.

General Errors Description
Solutions
No LED lighting or blinking after connecting to the mains
•Check if the charger is connected to mains supply properly
•Check if there are any problems with the mains supply or mains cable
•Check if the charger is switched on
•
Red Mains-LED is on, charger is connected to the battery,
but the charging process seems not working
•Check the connection to battery and if the polarity has been correctly
connected
•Check if the battery is damaged or has been deeply discharged
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
