ANY INTERRUPTION OF THE PROTECTION
CONDUCTOR INSIDE OR OUTSIDE THE APPARATUS,
OR DISCONNECTION OF THE PROTECTIVE EARTH
TERMINAL, IS LIKELY TO MAKE THE APPARATUS
DANGEROUS. INTENTIONAL INTERRUPTION IS
PROHIBITED.
FOR SAFETY REASONS THE CPU MUST BE MOUNTED
IN A 19-inch RACK WHICH HAS SAFETY COVERS
ACCORDING TO IEC65.
WHEN TWO CPUs ARE MOUNTED ABOVE EACH
OTHER THE MINIMUM DISTANCE BETWEEN THEM
MUST BE 50MM OR THE RACK MUST BE FORCE-AIR
COOLED.
USE ONLY FUSES OF THE TYPE AND RATING
SPECIFIED.
CAUTION
To prevent risk of overheating, ventilate the

a voltage, with respect to an
other terminal, exists or may
be adjusted to 1000V or more.
Yellow/Black Live part.
Yellow/Black This marking indicates that the
operator must refer to an
explanation in the Instruction
Manual, or that a specific
component must be replaced
by the component specified in
the documentation for safety
reasons.
White/Black Protective earth (ground)
terminal.
Cathode ray tubes
Components marked on the circuit diagram are
critical for safety and include those specified to comply
with X-ray emission standards for units using cathode
ray tubes and those specified for compliance with
various regulations regarding spurious radiation
emission.
When servicing units that use cathode ray tubes
(CRTs), the cathode ray tubes themselves, the high
voltage circuits and related circuits are specifically
chosen so that they comply with recognized codes
pertaining to X-ray emission.
Consequently, when servicing, replace the cathode
ray tubes and other parts with specified parts only. Do
not attempt to modify these circuits as any unauthorized
modification can increase the high voltage value and
cause X-ray emission from the cathode ray tube.
Handle the cathode ray tube only when wearing
shatterproof goggles and after discharging the high
voltage completely.
Earthing
The rear of a CPU has two separate screw terminals
for protective earth (PE) and video earth (VE).
These are normally connected by a metal strap. The
protective earth terminal is internally connected to the
protective earth conductor of the power cable. If
required, the central earth connection wire of the studio
can be connected to terminal PE.
In normal circumstances the connection between the
protective earth and the video earth should not be
broken.
The metal strap may be removed only if the studio (or
OB van) is equipped with separate protective and
video earth systems. Under these circumstances the
video earth terminal must be connected to the central
functional earth potential (video earth) of the studio.
This earth potential should have functional protective
and noiseless earth (FPE) qualities as stated in the
VDE regulation 0800/part2. A low impedance
interconnection of both earth conductors must be
provided at the central studio earthing point.
WARNING
THE UNIT MUST ALWAYS BE CONNECTED TO
PROTECTIVE EARTH.
Mains Lead Wiring for UK Users
The wires in the mains lead are coloured in accordance
with the following code:
GREEN AND YELLOW - EARTH
BLUE - NEUTRAL
BROWN - LIVE
As the colours of the wires in the mains lead of this
apparatus may not correspond with the coloured
markings identifying the terminals in your plug proceed
as follows:
• The wire coloured GREEN AND YELLOW must be
connected to the terminal on the plug marked with
the letter E or by the safety earth symbol or
coloured GREEN or GREEN AND YELLOW.
• The wire coloured BROWN must be connected to the
terminal marked with the letter L or coloured RED.
• The wire coloured BLUE must be connected to the
