Safety Instructions
Safety Summary
This informaton is intended as a guide for trained and
qualified personnel who are aware of the dangers
involved in handling potentially hazardous electrical/
electronic equipment. It is not intended to contain a
completelist of allsafety precautionswhich should be
observedby personnelin usingthis orother electronic
equipment.
The installation, maintenance and service of this
equipment involves risks both to personnel and
equipment and must be performed only by qualified
personnel exercising due care.
Personnel engaged in the installation, operation,
maintenanceor servicing ofthis equipment areurged
tobecome familiar withFirst Aid theoryand practises.
During installation and operation of this equipment,
local building safety and fire protection standards
must be observed.
Beforeconnecting the equipmentto thepower supply
of the installation, the proper functioning of the
protective earth lead of the installation needs to be
verified.
Whenever it is likely that safe operation is impaired,
theapparatus mustbe made inoperativeand secured
against any unintended operation. The appropriate
servicing authority must then be informed. For
example,safety islikelyto beimpaired iftheapparatus
fails to perform the intended function or shows visible
damage.
Thisproduct hasbeen designedand testedaccording
to EN60065.
Cautions and Warnings
Whenperforming service, besure toread and comply
withthe warning and cautionnotices appearing in the
manuals. Warnings indicate danger that requires
correct procedures or practices to prevent death or
injury to personnel. Cautions indicate procedures or
practices that should be followed to prevent damage
or destruction to equipment or property.
WARNING
THE CURRENT AND VOLTAGES PRESENT IN THIS
EQUIPMENT ARE DANGEROUS. ALL PERSONNEL
MUST AT ALL TIMES FOLLOW THE SAFETY
REGULATIONS.
ALWAYS DISCONNECT POWER BEFORE REMOVING
COVERS OR PANELS.
ALWAYS DISCHARGE HIGH VOLTAGE POINTS
BEFORE SERVICING.
NEVER MAKE INTERNAL ADJUSTMENTS, PERFORM
MAINTENANCE OR SERVICE WHEN ALONE OR WHEN
FATIGUED.
IN CASE OF AN EMERGENCY ENSURE THAT THE
POWER IS DISCONNECTED.
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
product correctly.
Connect the product only to a power source with
the specified voltage rating.
Only connect a Triax cable from the LDK 6
camera family to an LDK 6 CPU. Never connect it
to any other base station.
Never connect the Triax cable from a camera to a
CPU of a different family; never connect the LDK
family to the TTV family.
Do not allow system ground currents to exceed
1.5A in the outer shield of the triax cable or 0.2A
in other cable shields.
It is strickly prohibited to short circuit the inner
and outer shields of a triax cable used to connect
a camera to a base station.

Cathode ray tubes
Components marked on the circuit diagram are
criticalfor safetyandinclude thosespecified tocomply
withX-ray emission standardsfor unitsusing 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
notattempttomodifythesecircuitsasanyunauthorized
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
protectiveearth terminalis internally connectedto the
protective earth conductor of the power cable. If
required,thecentral earthconnectionwireof thestudio
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.
