Connection for
Battery Temperature Sensor
(temperature sensor 825 included in the standard delivery scope):
Lead
batteries (acid, gel, AGM): In case of
low outside temperatures
,
full charging
of the weak battery is
improved
by
automatic adaptation of the charging voltage to the
battery temperature
, and in case of summery temperatures
unnecessary battery gassing
and battery load will be avoided.
For
LiFePO4
batteries, the battery temperature sensor is required:
It serves for battery protection in case of high temperatures or particularly in case of low temperatures below 0 °C.
Silent Run Function:
Noise-optimised operation (night operation) at the touch of a button.
Power Pack Function:
Allows supply of the consumers without battery (such as during battery replacement).
Charging Cable Compensation:
Automatic compensation of voltage losses on the charging cables.
Integrated On-board Mains Suppression Filter:
Unproblematic parallel operation with solar systems, wind and petrol-
driven generators, dynamos etc. on one battery.
Electronic system humidity-proof.
Charging Aid for Deeply Discharged Lead Batteries:
Gentle preliminary charging of the (lead-acid, gel, AGM) battery to
8 V, followed by powerful support of the battery, in case of possibly switched-on consumers.
Battery Lifetime and Efficiency:
Keep the batteries cool, LiFePO4
preferably
above 0 °C
. Choose an appropriate location for
installation.
Store
only fully charged batteries and recharge them periodically.
Open lead-acid batteries and batteries being "maintenance-free according to EN / DIN":
Check the acid level periodically!
Recharge deeply discharged batteries immediately!
LiFePO4: Only use complete batteries with BMS and safety circuit.
! Deep discharge is to be absolutely avoided !
Installation of the Unit:
Install the charger
near batteries
I
(Master) and II (short charging cables)
at a clean, level and hard mounting surface,
which is protected from moisture and humidity.
The unit can be installed in any position. Protect the unit from aggressive battery gases.
Despite the charger's high efficiency, heat is produced, which is brought out of the casing by means of the built-in fan. The
vent holes of the unit should never be covered (minimum distance 10 cm) to ensure full charging capacity. Ensure sufficient
ventilation
in the
environment of the unit,
so that the heat can be dissipated.
Otherwise, in the event of overheating, the charger will reduce its charging capacity.
Solid and vibration reducing installation by means of the rubber feet. Never remove these rubber feet!
Battery Connection and Battery Settings for Start-up:
Observe the connection plan with the cable cross-sections and the lengths of the cables, the polarity, as well as
the fuses near the battery!
1.
Connect the main battery to the large terminals "
- Com.
" and "
+ I (Master)
" observing the correct polarity.
2.
Fasten the temperature sensor at battery "I" (master) and at the terminals "
T T
"
(option).
3.
Never forget to set the charging program 1) - 8)
for the type (design) of main battery I (master), from
page 6.
4.
Option: Large terminal
"+
II
"
: Connect the second main battery II at this location and to ground observing
the correct polarity.
The main battery
II
can be at choice:
a.)
A further battery (bank) of the same type as main battery I (switch II=I, see table 2
).
b.)
The vehicle's starter battery (full charging current, own charging program for starter batteries, II<I,
table 2).
5.
Option: Small terminal
"
+ III
"
12 V can be used as:
a.)
Signalling port 12 V for indicator or vehicle engine immobilizer by external relay.
b.)
Auxiliary charging port for the vehicle's starter battery, if option 4. a). has already been used.
Insert the mains plug (unit rear), and the automatic charging process starts.
Main Charging Port "Battery I" (Master):
Connect the main battery observing the recommended cross-sections and lengths for charging cables according
to
Table 1
.
Note: If the unit is used with only 1 battery, use this charging port I (master).
