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 mtr 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 type number plate, 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):
AC Current Minimum cross section:
3-4 Amp 0.5 mm² AWG 19
4-6 Amp 0.75 mm² AWG 18
