5 INSTALLATION
During installation and commissioning of the Mass Combi,
the Safety Guidelines & Measures are applicable at all
times. See chapter 2 of this manual.
5.1 UNPACKING
In addition to the Mass Combi the delivery includes:
• a battery temperature sensor;
• MasterBus - Serial interface + crossed wired RS232
cable (60 cm);
• this user’s manual.
After unpacking, check the contents for possible damage.
Do not use the product if it is damaged. If in doubt, contact
your supplier.
Check from the identification label (see section 1.6)
whether the battery voltage is the same as the DC-input
voltage of the Mass Combi (e.g. 24V battery set for a 24V
input voltage). Also check that the AC output voltage and
output power of the Mass Combi satisfies loading
requirements.
5.2 ENVIRONMENT
Obey the following stipulations during installation:
• The Mass Combi is designed for indoor use only.
• Ambient temperature: 0 ... 60°C / 32°F … 140°F;
(power derating above 25°C / 104°F to decrease the
internal heat sink temperature)
• Humidity: 0-95% non condensing
• Mount the Mass Combi on a solid surface, with the
connecting cables downwards.
• Make sure that the hot air produced during operation
can be discharged. The Mass Combi must be mounted
in such a way that obstruction of the airflow through
the ventilation openings will be prevented.
• No objects must be located within a distance of 10 cm /
4 inch around the Mass Combi. See also section 5.7.
• Do not locate the Mass Combi in the same
compartment as the batteries.
• Do not install the Mass Combi straight above the
batteries because of possible corrosive sulphur fumes
5.3 WIRING
The wiring is connected inside the connection
compartment. If necessary, the wiring can be fed from the
top to the bottom side of the cabinet along the back of the
cabinet.
Always feed the wiring through the cable glands of the
cabinet, and then connect the wiring to the terminals. Fix
the phase line wire to terminal L, the neutral wire to
terminal N and the ground wire to terminal PE.
5.3.1 AC-wiring
For a safe installation the correct wire cross section must
be applied. Don’t use a cross section that is smaller than
indicated. See table below to select the appropriate cross
section for the AC wiring:
AC-Current Minimum cross section:
in mm² AWG
15-20 Amp 2.5 mm² AWG 13
20-32 Amp 4 mm² AWG 11
32-48 Amp 6 mm² AWG 9
48-80 Amp 10 mm² AWG 7
Recommended wire colours (refer to local rules):
• 230V AC installations:
Wire color Meaning
Must be
connected to:
Brown or black Phase L1
Blue Neutral N
Green/Yellow Earth PE / GND
The maximum current passing the Mass Combi must be
limited. Therefore the AC-input must be protected by a
fuse, as specified below.

input fuse
All models 50A
