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 manual.
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' on page xiii), 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. For details of how to remove Volex locking type plug,
see 'Power' below.
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 system 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 fitted on each supplied mains cable, which plugs into
a mains IEC connector on the unit. 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, 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 M32 Control
Centre while power is being applied to it. Switch the power off first.
Before switching the M32 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 suitable lifting equipment or transporting gear, or sufficient
additional personnel.
Do not insert your fingers 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.
Ensure that all underside vents are left clear during operation.
