•
User 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 1.2)
whether the battery voltage is the same as the nominal
output voltage of the ChargeMaster Plus (e.g. 24V battery
set for a 24V battery charger).
3.2 Environment
Obey the following stipulations during installation:
•
The ChargeMaster Plus is designed for indoor use
only.
•
Ambient temperature: -25°C ... 80°C / -13°F … 176°F;
(power derating above 40°C / 104°F to decrease the
internal heat sink temperature).
•
Humidity: 0-95% non-condensing
•
Mount the ChargeMaster Plus vertically, with the
connecting cables downwards.
•
Do not expose the ChargeMaster Plus to excessive
dust, aggressive environments, ammonia or salt.
•
Make sure that the hot air that is developed during
operation can be discharged. The ChargeMaster Plus
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 ChargeMaster Plus.
•
Do not locate the ChargeMaster Plus in the same
compartment as the batteries.
•
Do not install the ChargeMaster Plus straight above
the batteries because of possible corrosive sulphur
fumes.
•
If the ChargeMaster Plus is installed in the immediate
vicinity of living areas, take into account that the fan of
the ChargeMaster Plus can produce noise when
operating.
•
Although the ChargeMaster Plus fully complies with all
applicable EMC limits, it may still cause harmful
interference to radio communication equipment. If such
interference appears, it is recommended to increase
the separation between the ChargeMaster Plus and
the equipment, to relocate the receiving antenna or to
connect the equipment to a circuit different from that to
which the ChargeMaster Plus is connected.
3.3 Wiring
WARNING!
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.
3.3.1 DC wiring
Keep in mind that high current will pass through the DC
wiring. Keep the cable length as short as possible, this will
keep the system efficiency as high as possible. The
recommended minimum cross section of the battery
cables is:

<3m / 10ft
3-5m / 10-16ft

25mm² / AWG2
24/60-3

35mm² / AWG2
Use ring terminals on the ends of the wires. The terminals
must be crimped with a proper crimping tool. Use the
following wire colors for DC wiring color or at least different
colors to make a clear distinction between the positive and
negative wire from the battery:

– (NEG)
Lay the positive and negative cables next to each other to
limit the electromagnetic field around the cables. The
negative cable should be connected directly to the
negative post of the battery bank or the ground side of a
current shunt. Do not use the chassis frame as the
negative conductor. Tighten securely. The positive battery
