Included in the ECONET module upgrade kit are two plastic printed circuit

board support posts. These must be fitted to the main printed circuit

board before installing the ECONET module.

The positions at which these posts are to be fitted are shown in figure 1.

When fitting the P.C.B supports, ensure that the base flange does not

interfere with any component on the P.C.B. To fit the support, insert one

end into the hole in the P.C.B and press down gently.

hen the support is correctly fitted, it will not be possible to withdraw

it from the hole in the P.C.B. Care must therefore be taken to ensure the correct

positioning of the P.C.B support before pressing it home.

When the P.C.B supports are installed on the main P.C.B, the ECONET module

should be placed in position ensuring that:

1. The pins of PL1 on the ECONET module are aligned with the corresponding

holes in SKT5 on the main P.C.B. The two WEST most holes of SKT5, labelled

'a' and 'b', are not used.

2. The pins of PL2 on the ECONET module are aligned with the corresponding

holes in SKT6 on the main P.C.B.

3. The P.C.B supports are aligned with the corresponding holes on the

ECONET module P.C.B.

When you are satisfied that all the pins and supports are correctly

aligned, the ECONET module P.C.B may be pressed gently into place. The

ECONET module is correctly seated when the barbs on the tips of the P.C.B

supports have cleared the surface of the ECONET module P.C.B. An audible

click should be heard when the barbs spring into place securing the P.C.B.

Take care not to exert too much pressure when pressing home the ECONET module

P.C.B, this may lead to damage of the various connectors.
