When more than one individual power supply is at the equipment room
or at a site or satellite location, an ac power strip (Figure 2-24) must be
installed to accommodate the various sizes of power supplies.
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.
