January 2012 3.6 Supply Voltages in the HSCI System 185
3.6.4 Power supply of the CC 61xx
The CC 61xx controller unit is supplied with a power of +5 V by the power sup-
ply units via supply bus X69 and connector X74, see page 186.
The control monitors the 5 V supply voltage. If it drops below 4.75 V, the error
message 5 V power supply too low appears. If it rises above 5.4 V, 5 V power
supply too high is indicated.
For information on the power supply units, refer to the "Inverter Systems
and Motors" Technical Manual.
