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 0V is connected internally to the
chassis.
To completely isolate this equipment from
the AC mains, while observing full safety
precautions (see “Power”), switch off the
isolator switch (above the mains power
sockets on rear of control centre) and then
switch off 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 100VAC to
240VAC.
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 fitted on each
supplied mains cable, which plugs into a mains
IEC connector on the equipment. When fitted
properly the Volex plug locks into place,
preventing it from working loose, or being
inadvertently knocked loose or pulled out. To fit
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 fitting 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
off first.
Before switching the control centre on or off,
make sure that all monitor loudspeaker power
amplifiers are turned off 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
