9.6.2. When expanding the power supply for external equipment
Let us assume that one expansion power supply is added to the system solely to cover the shortage of power
to be supplied to external equipment as the result of connecting many external equipment or mounting many
components in the rack.
Note: Remove the jumper wire placed between the 24V IN and OUT terminals of the terminal block located on
the rear panel of the Junction Panel JP-0410.

9.6.3. When expanding the power supply for internal equipment
When many components are mounted in the rack, the power supply system needs to be divided using an
expansion power supply.
Memo
• Leave a jumper wire connected between 24V IN and OUT terminals of the terminal block located on the rear
panel of the Junction Panel JP-0410.
• Supply power to the Integrated Control Panel EP-0510 from the JP-0410.
• Connect the output terminal of the Emergency Power Supply Panel DS-029B to the DC input terminal of the
expansion power supply.
