6.5.1 Power Supply

By clicking on the link Power supply on the status page a new window is displayed showing

important information on the status of the two power supply sources (mains and battery).

Normally, the ITC is powered via the 230 V mains. In this case, the status displays "Nor-

mal". If a battery is connected and the mains fails, the battery automatically provides the

necessary power for the ITC and the status changes to "EPS since..h..min..s". If the battery

voltage is too low (< 10,8V) the ITC goes into a secure mode in which it can no longer

transmit. (see chapter 7.2.1). The ITC automatically transfers to normal operation as soon

as the mains is available again.
