INSTRUCTIONS FOR MGX BATTERY CHARGERS
The battery charges of the MGX series are controlled by an internal microprocessor that enables automatic recharging of batteries and
stores the behaviour of the battery charger during its use.
This device had been developed for a professional use. For best results and safety, the user is required to read, follow and keep these
instructions carefully.
The manufacturer is not responsible for any damage due to improper use.
BATTERY
The battery voltage has to correspond to the MGX rated voltage (see rating data, for example 24V).
A label on the MGX indicates the correct rechargeable battery type. Check that it matches the features of your battery. If necessary, it is
possible to change the programming in order to adapt the MGX to your battery. Make contact with the supplier in order to carry out this
change.
INSTALLATION
To ensure maximum safety, installation has to be carried out as indicated by the manufacturer.
Any work on the charger must be carried out by qualified and authorized technical personnel.
WARNING: There is a rick of electric chock inside the box.
After unpacking be sure that the device is in perfect condition; in case of doubt, do not use it and contact the supplier. It is better to install
the MGX indoors, in a room free of humidity, acids or dust, with room temperature between 0-40°C. During use do not obstruct the venti-
lation holes. Any overheating of the MGX will reduce the output current; if overheating continues, charging will be stopped (see SPECIAL
SIGNALS).
ELECTRICAL SUPPLY
Be sure the rating data of the battery charger is compatible with the mains power supply (single-phase, voltage, frequency, power). Plug
into a socket equipped with protections that comply with local standard regulations. If you have to use an extension cable, contact the
manufacturer for correct technical information.
The replacement of the supple cable has to be carried out by a qualified personnel.
BATTERY CONNECTION
Respect the polarity: red wire to + and black wire to -.
Do not use extension cables without the manufacturer’s approval.
USE
Connect the battery and the power supply cable. LEDs light up for 2 seconds (PAN. 1), then only the RED LED stays on (PAN. 2). If this does
not happen, check the connection on the battery and supply.
The MGX is unable to activate the charging if the voltage of the battery is lower than 0.3 V/Cell (i.e., 3.6 V for a 24V battery). If everything
is functioning properly the charger performs the whole charge and stops with the GREEN STOP LED illuminating (PAN 3).
The time of charge depends on the discharge level, the battery type and the programmed charge cycle.
For lead acid, gel or AGM batteries, 80% discharged, the whole recharge lasts 10-14 hours.
Shorter times are possible if the battery is less than 80% discharged.
Longer times are possible if the battery is more than 80% discharged.
SPECIAL SIGNALS
When the microprocessor detects a problem, it stops charging and signals this by flashing the two LEDs (PAN. 4). The different possible
problems are:
Overheating: the thermal conditions interrupt the current in order to avoid damage
