2 Safety and Precautions
Observe all safety information both on the equipment and in this section.
Environmental
Always ensure adequate ventilation is provided for the equipment by following the rack design
rules and guidelines provided in the ASL System Design Guide.
The temperature and humidity ranges shown in the specifications for this equipment 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.
Objects containing liquids should not be placed upon the equipment.
Weight Safety
The V2000 mainframe with amplifier and interface cards fitted is heavy (max. 15 kg). Move and
handle with care to avoid strain or impact injuries. Install amplifier modules after mounting
mainframe into the 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.
The supporting rails must be capable of safely bearing the weight of the equipment (max. 15 kg).
ESD Precautions
The V2000 mainframe, interface cards and amplifier modules contain static-sensitive devices.
Observe ESD precautions when handling the mainframe with the lid removed, the interface cards
or amplifier modules.
Battery Handling
Work on the batteries should be carried out by qualified personnel only.
Always use insulated tools.
Batteries shall not be exposed to excessive heat such as sunshine, fire etc.
EMC
In the close proximity of some radio frequency transmitters, the signal to noise ratio of this equipment may be
reduced. If this occurs, re-location of the equipment or the signal cables is recommended.

V2000 – Installation Guide
U-0623-0291.docx – Issue: 04 complete, approved
Page 5 of 40
Electrical Safety
The V2000 is designed for professional use only and must be installed in a restricted access
location such that there is no operator access to the V2000 equipment, wiring or battery.
Ensure power supply cabling is adequately rated for the unit’s operating current and
temperature, and is protected against 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 exceeding 1000 amps.
Using too thin a cable can cause a safety hazard and will give excessive voltage drop and
operational failure.
Always ensure that the equipment is correctly earthed by connection to an AC mains supply with
a protective earthing connection.
Note that if the V2000 is 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.
The V2000 is protected from overload by single pole phase fusing. If connected to an
unpolarised mains the building installation must provide double pole phase/neutral fusing of
appropriate rating.
Always replace blown fuses with the correct type and rating.
This equipment 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 instructed personnel.
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.
Do not allow tools or unconnected cables to rest on top of batteries.
The V2000 may be energised after operation of a fuse or power off by the front panel MAINS
and BATTERY supply switches.
Always isolate the mains and battery supplies by switching off the rack mains and battery supply
isolation switches before installation, servicing or maintenance. In installations where the rack
mains and/or battery supply isolation switches are not accessible, unplug the power supply
cables from the V2000.
The V2000 may still be energised after isolating the mains and battery supplies.
After the mainframe ‘processor’ LED has stopped flashing leave the V2000 for another 5 minutes
before attempting internal servicing.
The D150 and D500 amplifier modules may be plugged or unplugged with power still connected.
To protect against electric shock and damages to the equipment:
•Always use the ejector lever and the slot guides (bottom and top of mainframe) to plug or
unplug an amplifier module.
•Do not touch the circuit board, any component or adjacent hardware.
•Do not allow the amplifier module to come in contact with any adjacent hardware.

V2000 – Installation Guide
U-0623-0291.docx – Issue: 04 complete, approved
Page 6 of 40
The LSZDC Surveillance Card may be plugged or unplugged with power still connected if
necessary. Wherever possible, to avoid the risk of short-circuit with adjacent hardware,
disconnect the power supply to the V2000 backplane before plugging or unplugging the LSZDC
card.
Disconnect power supply to the V2000 backplane by switching off the MAINS and BATTERY
switches on the mainframe front panel behind the removable front panel.
Fire / Burn Safety
Batteries contained within the rack can deliver very high currents that could cause fire or burns.
Take care to avoid short-circuits of the battery terminals by tools or jewellery.
Do not allow tools or unconnected cables to rest on top of batteries.
Use caution when working with the V2000 mainframe. The mainframe case temperature can
exceed 70°C.
Ground Loops
It is possible to form a ground loop (earth loop or hum loop) when connecting pieces of audio equipment
using unbalanced connections that provide alternative earth connections via their cable screens.
Such ground loops result in audible ‘hum’ from the system.
Never disconnect the mains earth from the plug to attempt to cure a ground loop. In the event of
a fault, the equipment casing could become live.
Blanking Plate Disposal
Any blanking plates removed from the V2000 as part of the installation process ideally should be
recycled as metal or otherwise responsibly disposed of by following WEEE protocols.
