3 Safety and Precautions
Environmental
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.
Weight Safety
!
!
This equipment is heavy (max. 20 kg).
Please move and handle with care to avoid
strain or impact injuries, and follow the
recommended installation procedure.
Install modules after mounting
mainframe in equipment rack.
!
!
Do not use the handles to lift or carry the
mainframe. The handles are designed for
sliding the unit into and out of the
equipment rack, and not to support its
weight.
Use the underside edges of the
mainframe to lift and carry it.
ESD Precautions
This product contains static-sensitive devices. Observe
ESD precautions when handling this product.
Cabling
Cables for the AC mains and DC battery supplies must
be adequately rated for the expected currents that it
will be carrying. Using too thin a cable can cause a
safety hazard and will give excessive voltage drop and
operational failure.
EMC
In the close proximity of some radio frequency
transmitters, the signal to noise ratio of this product
may be reduced. If this occurs, re-location of the
equipment or the signal cables is recommended.
Electrical Safety
!
!
This product contains wiring that is
energised to 230 V 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.
