Precautions
Before installing, setting up or operating this equipment make sure you have read and fully understand all of this section and the
“IMPORTANTSAFETY INSTRUCTIONS” at the front of this document.
This equipment is supplied by a mains voltage that can cause electric shock injury!
The following must be observed in order to maintain safety and electromagnetic compatibility (EMC) performance.
Safety warnings
Signal 0 V is connected internally to the chassis.
To completely isolate this equipment from the AC mains, while observing full
safety precautions (see “Power”), switch o the isolator switch (abovethemains
power sockets on rear of control centre) and then switch o the mains at
the three mains outlets. Unplug the three mains leads from the rear of the
controlcentre.
To avoid electrical shock do not remove covers.
General precautions
In the event of ground loop problems, disconnect the signal screen at one end of
the connecting cables. Note that this can only be done when the equipment is
used within a balanced system.
Do not remove, hide or deface any warnings or cautions.
Power
The power supplies contain LETHAL VOLTAGES greatly in excess of the mains
voltage and its rails can produce extremely large currents that could burn out
equipment and wiring if shorted.
The internal power supplies are of the switch mode type that automatically sense
the incoming mains voltage and will work where the nominal voltage is in the
range 100 VAC to 240 VAC.
Each mains inlet is to be sourced from its own separate wall-mounted mains
outlet socket. Otherwise, their mains sources must be suitably distributed so as
to meet local safety regulations.
A Volex locking type plug is tted on each supplied mains cable, which plugs
into a mains IEC connector on the equipment. When tted properly the Volex
plug locks into place, preventing it from working loose, or being inadvertently
knocked loose or pulled out. To t a Volex plug, insert it into the mains
IECconnector and push it in until it locks in place. Then, check to make sure it
is locked in place. To remove it, release its locking device and then pull it out.
Whentting or removing a Volex plug, always hold the plug itself and never use
the cable, as this may damage it.
During operation of the control centre, a minimum of two of its three mains
inlets must be connected and supplying power.
When removing the equipment’s electric plugs from the outlets, always hold the
plug itself and not the cable. Pulling out the plug by the cable can damage it.
Never insert or remove an electric plug with wet hands.
Do not connect/disconnect a mains power connector to/from the control centre
while power is being applied to it. Switch the power o rst.
Before switching the control centre on or o, make sure that all monitor
loudspeaker power ampliers are turned o or muted.
Handling the equipment
Completely isolate the equipment electrically and disconnect all cables from the
equipment before moving it.
When lifting or moving the equipment, always take its size and weight into
consideration. Use suitable lifting equipment or transporting gear, or sucient
additional personnel.
Do not insert your ngers or hands in any gaps or openings on the equipment,
forexample, vents.
Do not press or rub on the sensitive surface of the GUI screens.
If the glass of the GUI screen is broken, liquid crystals shouldn’t leak through the
break due to the surface tension of the thin layer and the type of construction of
the LCD panel. However, in the unlikely event that you do make contact with this
substance, wash it out with soap.
Installation
Before installing the equipment:
• Make sure the equipment is correctly connected to the protective earth
conductor of the mains voltage supply of the system installation through the
mains leads.
• Power to the equipment must be via a fused spur(s).
• Power plugs must be inserted in socket outlets provided with protective
earth contacts. The electrical supply at the socket outlets must provide
appropriate over-current protection.
• Both the mains supply and the quality of earthing must be adequate for the
equipment.
• Before connecting up the equipment, check that the mains power supply
voltage rating corresponds with the local mains power supply. The rating of
the mains power supply voltage is printed on the equipment.
Location
Ideally a cool area is preferred, away from power distribution equipment or other
potential sources of interference.
Do not install the equipment in places of poor ventilation.
Do not install this equipment in a location subjected to excessive heat, dust or
mechanical vibration. Allow for adequate ventilation around the equipment,
making sure that its fans and vents are not obstructed. Whenever possible, keep
the equipment out of direct sunlight.
Do not place the equipment in an unstable condition where it might accidentally
fall over.
Make sure that the mains voltage and fuse rating information of the equipment
will be visible after installation.
