9.4.5. Connecting a single emergency power supply panel to power amplifiers
The figure below shows the method of connecting the Emergency Power Supply Panel DS-029B to the power
amplifier panel. Refer to the figure when expanding power amplifier panels or designing the power amplifier
rack.
• Only a single power amplifier panel (up to 120 W) can be connected per output terminal of the emergency
power supply panel.
• When using the 240 W power amplifier panel, connect it to parallel-connected outputs 1 and 2 (or 3 and 4) of
the emergency power supply panel.
• When using the 360 W power amplifier panel, connect the emergency power supply panel's outputs 1 and 2
(or 3 and 4) separately to individual power amplifier panels.
