and a single 24V DC power connector that is connected to an MV-EXTPSU3 unit if a backup
power supply is required.
5.6 Vega-MV Frame Power Supplies
5.6.1 Mains AC Supply Power Socket
The Vega-MV frames have a single IEC power socket and the mains voltage
(100/240 volts) will be auto detected provided it is in the range 100-240V AC 50/60Hz.
A fuse is fitted under the pull-out flap in the IEC socket. A spare fuse is also located under the
pull-out flap, see Figure 42
For UK only use,
a mains cable with a minimum rating of 10A fitted with a 10A fuse is recommended.
This equipment may have more than one power supply (AC Mains and 24V DC backup).
To reduce the risk of electrical shock, disconnect all the power supply cords before
servicing.
