Connect the non-intrinsically safe circuits to terminals 1, 2, 3, 4, 5 and 6.
The terminal assignment is shown in the following table.
The double equipotential lead PAL (Fig. 9, terminals 7 and 8) guarantees
that disruptions of the PAL connection are identified.
Note:
The two PAL leads belong to the intrinsically safe circuit, see connection 7
and 8, Fig. 9. The terminals of the Terrabox TCB030 are also marked as
intrinsically safe terminals (blue).
This is
NO
protective ground link, the leads must
NOT
be coloured green/
yellow. The PAL connection can be made with a two-wire sheathed cable,
with no wire colours prescribed, i.e., all colours apart from green/yellow
are permitted.
The sheathed cable can be made in light blue. As the connecting
terminals are already marked in blue, there is no absolute necessity for
this.
