4 INSTALLATION
During installation and commissioning of the Mass Charger,
the important safety instructions are applicable at all times.
See chapter 2 of this manual.
Please check the contents of the box before you start with
the installation. The contents of the box need to be:
• The Mass battery charger;
• Battery temperature sensor (incl. 6 m cable);
• A MasterBus terminating device;
• This user’s manual;
If one of these items is missing, please contact your
supplier.
4.1 Installation environment
Choosing a location to install:
• Install the Mass charger in a well-ventilated room
protected against rain, snow, spray, vapour, bilge,
moisture and dust.
• Ambient temperature: 0 ... 60°C / 32°F … 140°F; (power
derating above 40°C / 104 °F to decrease the internal
heat sink temperature).
• Humidity: 0-95% non-condensing.
• Never use the Mass charger at a location where there is
danger of gas or dust explosions
• Mount the Mass Charger in such a way that obstruction
of the airflow through the ventilation openings is
prevented. No objects must be located within a distance
of 10 cm / 4 inch around the Mass Charger.
• Mount the Mass Charger vertically, with the connecting
cables downwards.
• Do not install the Mass Charger in the same
compartment as the batteries. Do not mount the Mass
Charger straight above the batteries because of
possible corrosive sulphur fumes.
4.2 Connections
Before making the connection between the battery charger
and the system be sure that the AC and DC system are
switched off. Remove the fuses in order to protect yourself
against unexpected start up.
4.3 Wiring
CAUTION!
The wire and fuse sizes stated in this manual are
given as example only. Prescribed wire and fuse
sizes may be different due to local applicable
regulations and standards.
4.3.1 AC wiring
Check if the voltage of your mains source or generator
corresponds with the AC input voltage of the battery charger
as mentioned on the identification label, see section 1.4.
Strip the cable according to fig. 5. It is important that the
green/ yellow earth wire is ± 1 cm (0.4 inch) longer than the
other wires. By accidentally pulling at the cable, the earth
wire stays connected to the Mass Charger longer which
offers additional safety. Connect the green/yellow wire to
PE, brown to L1 and the blue wire to the N terminal.
Don’t use a cross section that is smaller than indicated. See
table below to select the appropriate cross section for the
AC wiring (up to 6m / 20ft length):
