1.1 Safety and Reference Rules

The Battery Charger is made in accordance with the following rules:

Low voltage (2006/93/CE) and Electromagnetic compatibility

and Electromagnetic compatibility (2004/108/CE).

Electrical safety rules applied are EN60335

Charger is manufactured under ISO9001 norms

1.2 Thermal security systems and fuses

curity systems and fuses

Chargers are power supply devices. Their goal is to transfer energy from the electric grid to the battery. Therefore

they are devices that tend to create heat.

This must be considered as totally normal especially during the first hours of the charging cycle.

Charger is provided with two thermal protections

thermal protections. One to be considered in an absolute way the other one in a

preventive way (derating):

1) The charger has two or more temperature sensors

maximum temperature is reached (typ. 90

The charger will restart automatically after

2) The second protection uses an algorithm

When the system is approaching the maximum permitted

is approaching the maximum permitted values it reduces the output current attempting to

temperature to values lower than the maximum ones

All Chargers have a fuse inside the cabinet

In case of reverse polarity of battery cables,

of battery cables, all models having"d" suffix are protected by relay. The others are protected

by fuse.
