The chassis half of the connector is bonded to the metalwork with the usual nuts,
bolts and spiky washers. The solder tag should be as long as possible so that the
length of the 'short wire' is a minimum. The twisted pair (from the signal pins - pin 2 &
pin 3) are soldered onto the motherboard adjacent to the 'input RFI filter' compo-
nents.

CADAC 8019 and 8020 switch-mode power supply units were introduced during
November 1998. The a.c. input supply has been ‘standardised’ at 208V to 240V 50/
60Hz.
The 8019 “18V” unit is rated at 100A per rail and the 8020 “13V” unit is rated at 100A.

The 8019 ±18v unit is based on two ADVANCE F20006 ‘power-blocks’, with addi-
tional circuitry as shown on CADAC drawing number C3.8015.
The a.c. input is connected to the PSU via a 3-core cable, CMA reference 3183TQ –
BASEC approved, rated at 20A.
Under no circumstances, should the 8019 PSU be used without a SAFETY EARTH
connection.
Failure to follow this instruction is both a fire and safety hazard.
