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.
