66-TYPE HARDWARE
Individual Power Supplies
Individual power supplies (Figure 4-10) can be used for powering from the equipment room,
site or satellite locations, or information outlets. An individual power supply can power only
one voice terminal. Table 4-D contains the individual power supply limitations for distance,
wire gauge, and adjuncts.
When a number of individual power supplies are used at the equipment room or at a site or
satellite location, an ac power strip (Figure 4-11) is installed to accommodate the various
sized power supplies. The outlets on the ac power strip must be spaced 3.5 inches (8.89 cm)
to 4 inches (10.16 cm) apart with the plug inserts perpendicular to the strip.
Note: A 543A power unit (Comcode 104 034 541) may be required for inrush protection
for a 20-amp 120-volt ac line serving multiple 329A power units. Contact your PSC for
details. Most multiple powering requirements should be served by the 346 modular
bulk power supply.
