WIRING OF PRIMARILY SUPPLY LEADS (FOR U.K. ONLY)
If any one of the bands shown in Fig. 66 is removed for some
reason, be sure replace it to the original position and same
appearance as before.

Checking the lead process
Power Transformer 10 pin lead
Check that the lead process is as specified as above.
Connect the 2 pin lead from
BI101 under the PWB via
the nylon band A .
Passing through
the electrolytic condensers
Tie the 2 pin lead at
the back of the PWB.
Tie the 8 pin lead
and the 10 pin lead
at the two positions.
Main PWB
(CNP308)
Tie the 2 pin lead
at the back of the PWB.
2 Pin lead
connected
from BI101.
Make the 2 pin lead
as tight as possible.
POWER-SW
(BI101)
POWER PWB
(BI101)
Connect the 2 pin lead via the
position as shown in the figure and
take up the slack in the direction as
shown by the arrow to avoid stress
on the PWB.
