5.7.2.2 Remote display power supply
The remote display power supply is a normal AC power supply with no battery back-
up. This means that if data transmission with the Silcon DP300E has to continue
during break down of the commercial utility, the remote display has to be supplied
from the Silcon DP300E or another uninterruptible power source.
