In units with a 680 W power supply (AC or DC), observe the RF card limitations specified
in chapter 7.1. With the 780 W DC PSU there are only limitations for a mains voltage
from 24 to 36 Vdc which are also specified in chapter 7.1. To decide which type of PSU
is equipped, look up the HID of the PSU on the Serial and ID Numbers page of the SW
