4.5.1.2 Single Phase Power Supply
The Z16HD+ single phase transmitter uses four main power transformers working in
groups of two. These are designated PS1, PS2, PS3 and PS4. Figure 4-10 shows the
placement of each of the 4 power supplies and connection points for installation or
removal of the supplies. Due to the size of the single phase supplies a second cabinet is
required for PS3 and PS4. This requires that each cabinet have separate AC line feeds
from separate wall breakers and some interconnections between the cabinets.
