2 OPERATION – PRESENTATION
2.1

OPERATING PRINCIPLE

The shore-power units allow getting in a single cabinet the AC on-board protection and a battery
charger.
The shore-power unit housings meet the European on-going rules. Compact and lightweight, they
provide practical entry for the cabling that reduces mounting time.
The user protection is insured by a 16A/30mA differential circuit breaker. The on-board utilization
outputs are protected by (depending on model) 2, 3 or 4 10A DPN thermo-magnetic circuit breakers.
The battery charger function is made by an H.F. switch mode CRISTEC CPS3 PCB.
Their design is based on a high-frequency split converter that transforms the AC signal into regulated
and filtered DC current. They can operate as a battery charger and as a DC power supply.
Once the types of battery and charge have been selected the operating of the charger of the shore-
power unit is entirely automatic. It can remain connected to the batteries permanenty (unless otherwise
specified by the manufacturer or supplier of batteries) and does not need to be disconnected when
starting up an engine (marine application), because it is equipped with rectifier diodes.
The appliance's output voltage is sufficient to recharge 1, 2 or separate 3 batteries (integrated charge
distributors, separation of batteries). All models feature an output suitable for recharging an engine
battery (BAT D output, marine application). The charger's maximum output is the rated current
distributed to each output according to the batteries' usage needs.
Each output can deliver the rated current.
Not all the outputs have to be connected. However, if only one output is used, we recommend
interconnecting outputs BAT1, BAT2 and BAT D to one another (optional).
2.2 OVERVIEW PRÉSENTATION
The shore power units are divided into 2 areas:
•
The entry area, AC distribution.
•
The battery charger area

3 INSTALLATION

This paragraph deals with installation-related arrangements.
Installation and initial commissioning should be carried out by an electrician or professional installer in
accordance with the standards currently in force (for pleasure boats the applicable international standard is
ISO13297).
The installer should familiarize himself with this operating manual and inform users of the instructions for
use and the safety warnings set out in the manual.
The shore power unit has to be fixed by 4 M6 round screws (diameter of the screw < 10mm in order to allow
the opening of the cover).
Fixing distance: see the corresponding drawing in chapter overall dimensions.
