4.
Take care not to scratch the Lite during handling. Packaging foam should be used to
protect the paint when being handled on a trolley or pallet jack.
5.
Always ensure that lifting equipment and slings are adequately rated for the lifting
weight.
6.
Wear personal protective equipment such as safety shoes and gloves while handling
and mounting the Freedom Lite
7.
Always ensure that you have enough people on hand to perform the operation safely,
i.e. at least two persons to guide and stabilise and two persons to hoist or handle the
pallet jack(s).

Connecting the Freedom Lite
4.1
Power Cables
The Freedom Lite is simple to connect to the battery inverter. First of all you will connect
the positive and negative cables to the inverter terminals or DC busbar if applicable using
the applicable lugs (not supplied).
Danger: The Commercial HV and HV+ range operates at potentially lethal voltages and
hence the battery cables and connections must be treated with the utmost of respect –
prior to connecting the positive and negative cables to the inverter be sure to check that
the main battery circuit breaker is switched off. This will ensure that there are no short
circuits between the loose ends of the cables and will also avoid electric shock from the
battery during installation.
The cables are supplied with the Freedom Lite, permanently fixed into the unit and secured
onto the casing using compression cable glands. Attach crimp plugs to the ends of the cables
ensuring that the correct terminal size is used, and the lug is matched to the size of the
cable. The positive cable is red, and the negative cable is black. This is confirmed by + and –
signs on the battery casing beside the respective cables. See Tables 2.1 and 2.2 respectively
for the cable size and quantity fitted to each Freedom Lite model. The standard cable length
is based on the inverter standing on the floor or mounted on the wall as applicable adjacent
to the Freedom Lite battery so that the cable run is less than 3m (note that the standard
cable length is 3.0m, longer cables available on request up to 5m). Note the inverter should
always be on the right-hand side of the battery or opposite the battery with overhead cable
routing.
Longer runs should be assessed, and larger cables or busbars considered, for extending the
Freedom Lite DC connection with the objective of minimising voltage variation between the
battery and the other DC connected equipment. Double insulation welding cable is
recommended. In some instances, multiple cable lengths are used instead of using larger
cable to ensure easier routing and bending of cables in trunking.
The cables may be routed through trunking (or on cable tray) and connected into the
inverter on the positive and negative terminals respectively. The inverter terminals on most
