5.8 Connection to dedicated LPG tank
If the generator is connected to an LPG tank (or
bottle) that is used exclusively for the generator,
it is necessary to install a suitable pressure re-
ducer with a 30 mb outlet between tank and gen-
erator. As already specified, pressures higher
than this can seriously damage the generator.
The tank must be type-approved as per the laws
in force in the country of installation and must be
fitted at a point protected from any impact or high
temperatures.
For information on the electrical connection for
any fuel reserve indicator, please see the para-
graph on auxiliary connections.
5.9 Connecting two TIG3000G units in
parallel
Should it be necessary to double the available
power, it is possible to connect two TIG3000G
units in parallel (they must have the same or
compatible hardware and software revision lev-
els). The connection must be carried out follow-
ing the wiring diagram at Fig. 25.
1 = TIG 3000G #1
2 = TIG 3000G #2
3 = Battery (may be common)
4 = Data cable for parallel connection
5 = TIG #1 230 V output cable
6 = TIG #2 230 V output cable
7 = Connection point of the two outputs
8 = Load connection
The following rules must be observed when car-
rying out the parallel connection:
- the connections must be made with the genera-
tors switched off
- the maximum distance between the two genera-
tors must not exceed 10 metres
- the length of cables 5 and 6 from the outputs of
the generators to the junction point must be less
than 15 metres each, the lengths must be identi-
cal (a maximum difference of 1 metre is tolerat-
ed) and the wires must be of the same size
- make absolutely certain that the N, L and PE
connections to the user circuit are correct
- the two generators may share the same starter
battery or each may have its own
- with regard to the size of the cables used, com-
ply with the specifications in the paragraph on
electrical connections
If these rules are not complied with the overall
power output will not equate to the sum of the
outputs of the two generators, or worse still,
might create a malfunction with damage to the
generators.
In order for the two generators to be able to work
with the outputs connected in parallel, they need
to exchange data on the synchronisation and op-
eration. This is achieved through the special (op-
tional) data cable code 06688 (Fig. 25 ref. 4).
To carry out the data connection it is necessary
to remove the door from both generators. Then,
after running the lead through the cable holder
used for the other electrical connections, insert
the connectors at the end of the lead in the re-
spective 8-pole connectors (fig. 26 ref. 1).
