9.4.4. Connections

Connections of the Emergency Power Supply Panel DS-029B are classified into four methods a, b, c, and d

depending on the composition selected in the section "About the Emergency Supply Panel" on p. 8. Because

the operation and control sections are fundamental to the emergency broadcast system, any failure in their

operation will disable the function of the entire system. When two or more DS-029Bs are incorporated into the

system (connection methods c and d), the system's operating time can be extended by connecting all the

positive (+) and negative (–) REMOTE (left) terminals on all DS-029Bs in parallel. This permits all connected

batteries to be used as a backup power source for the operation and control sections.

Important: Be sure to connect the DS-029B's power source to the "UNSWITCHED" AC outlet located on the

JP-0410's rear panel.

Connection method a for the DS-029B

In this method, one battery (one DS-029B unit) is connected to supply power to both the operation/control

section and power amplifier panel.
