The battery charger performs a decreasing current profile called Wa in conformity with DIN 41774 regulations. This profile
is determined by the technical characteristics of the power transformer. The power transformer is in fact provided with
different tappings in order to make sure the charging profile will result correct.
It is then essential to "adjust" the power transformer to the Vac values using related cables on tappings. Here is
procedure to follow:
Note: Measure by a tester the real AC voltage during the charge and check it is the same as the
voltage set by the plug on the power transformer. Please match the voltage to the nearest value.
Please refer to section "INSTALLATION AND POWERING"
2.1
Series – 3N e 5N
These battery chargers are designed to work with 60Hz grid. They are available in two different series:
Series 3N – provided with simple LED interface. Suitable when you do not require to program the charger or to have
access to specific information. Note: PCB can be programmed in any case using an external keypad.
Series 5N – provided with LED interface, display and 4 keys. Charger display is provided with 4 digit (7 segments LED)
showing many information regarding the status of the charge: Voltage and battery current, Ah charged, duration of the
charge, type of anomaly and more. See all parameters at dedicated paragraph.
2.2
Models - Advanced and Pulse
Chargers are available in two models:
Advanced – refer to models performing a slow charge (typical. 10-13h). They are intended for daily overnight recharge
of a battery. They perform a cycle called Wa (DIN 41774).
Pulse – refer to models performing a fast charge (typical. 7-8h). They are intended for a double shift charge involving
one or more battery. They perform a cycle called Wap.

Choosing the place
•
Put the Battery Charger in a suitable place, allowing an adequate air change, far from any heat source.
•
Place the cabinet on a surface not inflammable as stone , concrete or metal.
•
Chargers are heavy devices. They must be secured to prevent accidental falls. Place them on the ground or use
robust shelves .
•
Make sure the Battery Charger command (OFF) have an easy access and that charging phase control panel (leds and
display) is well visible
