Always ensure adequate ventilation is provided
for the equipment by fitting 1U ventilation panels
above and below the equipment and do not
obstruct ventilation holes.
The temperature and humidity ranges shown in
the specifications for this product must not be
exceeded.
This equipment must not be installed in an area
that is subject to a corrosive atmosphere,
excessive moisture or may allow water or other
liquids to come into contact with the unit or its
external connections.
12.2 Electrical Safety
!
!
This product contains wiring that is
energised to 230 V RMS AC mains
and 100 V RMS audio signals at up to
20 kHz.
Terminals marked with the
symbol are hazardous, and the
external wiring connected to these
terminals requires installation by
qualified personnel only.
!
!
Always ensure that the equipment is
correctly earthed by connection to
an AC mains supply with a protective
earthing connection.
Ensure power supply cabling is
adequately rated for the unit’s
operating current and protected, in
case of short circuit, by a correctly
rated fuse or circuit breaker. This is
particularly important for supply
feeds from the 24 V backup batteries
which can deliver short circuit
currents of several hundred amps.
!
!
Always replace blown fuses with the
correct type and rating.
!
!
Note that this equipment is intended
for continuous operation and the
front panel mains switch is not
readily accessible without the use of
tools to remove the front cover.
Note that if the amplifiers are
connected as a system which is
permanently connected to the mains,
then an all-pole mains isolator with a
separation of 3 mm in each pole shall
be incorporated in the electrical
installation.
!
!
You must switch off AC mains and
battery supplies before
plugging/unplugging amplifiers or
you may damage the mainframe, and
amplifier card electronics.
!
!
External 24 V DC batteries connected
to this unit can deliver very high
currents that could cause fire or
burns. Take care to avoid short
circuits of the battery supply by tools
or jewellery.
