Heating may be required in cold conditions to keep the temperature above 0°C, since charging
the LiTE is not permitted below 0°C. Installation environments that regularly exceed 40°C
should employ cooling if practicable to ensure optimal service life of the LiTE unit.
Temperature storage or transport of the battery is permitted in the range of -20°C to 45°C,
however extended storage should be between 0°C and 25°C.
There is no minimum requirement for spacing around the battery from other objects,
provided that these objects do not generate heat. Note, however, that access is required to
the USB programming port and the CAN Bus sockets and cables exit on the opposite end of
the SoC and circuit breaker.
The breaker is rated at IP40 when the lens is open.
For seaside residential properties it is highly recommended the LiTE Marine units be installed
in the same ambient temperature-controlled environment as mentioned above with no
directed exposure to sea water. The units are rated at IP65 for corrosion and moisture
protection.

Connecting the Freedom LiTE Marine
4.1.
Power Cables
The Freedom LiTE is simple to connect to the DC bus or battery inverter. First, you will connect
the battery positive and negative cables to the inverter terminals or DC busbar using the
applicable lugs.
Caution:
Prior to connecting the positive and negative cables to the inverter or DC busbar, be sure to
check that the main battery circuit breaker is
switched off
. This will ensure that there are no
short circuits between loose ends of the cables.
The cables are supplied with the Freedom LiTE Marine, permanently fixed into the unit, and
secured onto the casing using compression cable glands. Attached crimp lugs to the ends of
both cables ensuring that the correct terminal size is used. Also be sure to match the size of
the cable to the lug. The positive cable is red, and the negative cable is black. See Table 2.1
for the cable size and quantity fitted to each Freedom LiTE Marine model.
The cable sizes are based on the inverter or main DC busbar being close to the Freedom LiTE
battery so that the cable run is less than 5m (note however that the standard cable length is
1.8m, longer cables available on request).
Cable runs longer than 5m should be assessed, and larger cables considered for extending the
Freedom LiTE cables, to minimise voltage drop. Double insulation welding cable is
recommended.
