ONNECTING THE BATTERY
The VarioString is a device which DC (battery) connection is to be connected exclusively to a battery.
Most of the time, lead-acid batteries with liquid (VLA, VRLA) or gelled (GEL) and AGM electrolyte
may be used. It can be easily configured to create charge profiles that are compatible with these
various types of lead-acid batteries.
In any case, the max charge current should be within the limit established by battery manufacturer.
If necessary, the charge current can be limited with the aid of parameter {14001}.
4.2.1 Precautions when using the batteries
The batteries should only be chosen, dimensioned and installed by qualified personnel, trained in this
specific area. When working with batteries, a second person is required in order to give assistance in
case of problems.
Lead-acid batteries with liquid or gelled electrolyte produce a highly explosive gas during normal
use. Avoid any source of sparks or fire in the immediate vicinity of the batteries. The batteries must be
kept in a well-ventilated place and installed so as to avoid accidental short-circuits when
connecting.
Never try to charge frozen batteries.
It is advised to never work alone with batteries. The presence of a second person is necessary to
provide assistance in the event of a problem.
Sufficient fresh water and soap must be kept close at hand to allow adequate and immediate
washing of the skin or eyes affected by accidental contact with the battery acid.
In the event of accidental contact of the eyes with acid, they must be washed carefully with cold
water for 15 minutes. Then immediately consult a doctor.
The battery acid can be neutralized with baking soda, among other things. A sufficient quantity of
baking soda should be available for this purpose.
Particular care is required when working close to batteries with metal tools. Tools such as screwdrivers,
open-ended spanners, etc., may cause short circuits. Sparks created by short-circuits may cause the
battery to explode. Therefore these kinds of tools must always have isolated handles and never be
placed on top of a battery.
When working with batteries, all metal jewellery such as rings, watches with a metal bracelet,
earrings, etc., must be taken off. The current supplied by the batteries during a short circuit is
sufficiently powerful to melt the metal and cause severe burns.
Batteries at the end of their life-cycle should be recycled in accordance with directives from the
responsible local authorities or the battery supplier. The batteries should never be thrown into fire as
they may explode. Under no circumstances should you try to take apart or dismount the battery, as
they contain toxic and polluting materials.
For ungrounded battery systems, always check that they are not inadvertently grounded before
starting working on the batteries.
Always follow carefully the instructions of the battery manufacturer.
If the battery voltage exceeds 68V, the charger turns off and starts again when the voltage is lower
than 64V.
Using the VarioString connected to any other type of DC source without battery is strictly
forbidden and may cause significant damage to the equipment and / or to the source.
The use of other battery types like Ni-Cd, Li-ion or other is possible if the charge profile is
properly programmed, in accordance with the specifications of the battery manufacturer,
in agreement with the battery manufacturer and under the responsibility of the installer.
