External Power Supply Unit

Mains Supply

The external PSU (power supply unit) supplied with the VENTURA

Console is of an ‘auto- sensing’ type — i.e. it will automatically adjust to

any mains supply voltage or frequency within the following ranges:

Mains Voltage:

100 to 240V a. c.

Mains Frequency:

50 to 60Hz.

Mains Supply Lead & Plug

A mains lead is provided which is fitted with an IEC/ Euro plug —this

connects to the socket on the PSU.

Because there are many different types of mains connectors, the other end

of the mains lead is ‘bare- ended’. Connect a suitable mains plug in

accordance with the following details:

Wire Colour Connect to Terminal

Brown ‘L’ or ‘Live’ (or coloured red or brown)

Blue ‘N’ or ‘Neutral’ (or coloured blue or black)

Green & Yellow ‘E’ or ‘Earth’ (or coloured green or green &

yellow)

WARNING

If you are unsure of the connections, or if the markings in your plug

do not match those given above, consult a qualified electrician.

If the plug has provision for an internal fuse, a 5 Amp fuse must be

fitted. If not, the supply must be protected by an external 5 Amp

fuse or circuit breaker.

THIS APPLIANCE MUST BE EARTHED.

Connection Procedure

 Connect the ‘flying lead’ of the PSU (fitted with a 5- pin DIN plug)

to the power socket of the Ventura console.

 Operate the rocker switch on the PSU to turn the console On or

Off.

When the supply is On, the red indicator on the PSU will be lit, and the

LCD Panel backlights on the console will also be lit. With 100V or 110V

supplies, there may be a short delay before the indicator illuminates — this

is perfectly normal.

Internal Memory Back-up

The Ventura console contains a battery, which is used to preserve the

settings and data held in the internal memory.

When fully charged, the battery will maintain the memory contents for up to

12 months without the desk being powered.

IMPORTANT NOTE

To avoid loss of data, ensure that the battery is fully charged by powering

the console for 24 hours before using it for the first time and also after

prolonged periods of storage.
