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.
