The older version of 8020 +13v/48v unit is based on one ADVANCE F20006 ‘power-
block’, with additional circuitry as shown on CADAC drawing number C3.8016. The
new version is based on PowerOne PSUs (serial number 34949 onwards).
The a.c. input is connected to the PSU via a 3-core cable, CMA reference 3183TQ –
BASEC approved, rated at 20A.

If replacing a switch-mode power supply unit is required, please note the following:
■
■
■
■
Make sure that the power supply system’s power switches are in the position
OFF and disconnected from the mains.
■
■
■
■
The work should only be carried out by a suitably qualified electrician.
■
■
■
■
Be careful to observe correct polarity when connecting the new PSU.
■
■
■
■
Note that a console must never have one voltage without the other, for example
+18V must never be fed into the console without -18V.
When switching the power supply system back ON after replacement has taken
place, make sure that both LEDs on the front of the PSU-system come on. If only
one LED comes on, let go of the ON push-button immediately. Failure to do so may
lead to fire hazard and major damage to the console.
NOTE: Under no circumstances, should the 8019 or 8020
PSU be used without a SAFETY EARTH connection. Failure
to follow this instruction is both a fire and safety hazard.
