4 INSTALLATION
During installation and commissioning of the Mass
Charger, the important safety instructions are applicable at
all times. See chapter 2 on page 4.
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. 6m cable);
a MasterBus terminator;
the user manual.
If one of these items is missing, please contact your
supplier.
4.1
Location
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 10cm/4inch 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 type number plate. See
section 1.4 on page 3.
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.
For a safe installation the correct wire cross section must
be applied. Do not use a cross section that is smaller than
indicated. See the following table to select the appropriate
cross section for the AC wiring (up to 6m/20ft length):

AC safety grounding
WARNING
The ground wire offers protection only if the
cabinet of the Mass Charger is connected to
the safety ground. Connect the ground
terminal (PE/GND) to the hull or the chassis.
CAUTION!
For safe installation it is necessary to insert a
RCD (Residual Current Device; earth leakage
switch) in the AC input circuit of the Mass
Charger.
