Table 2-13 Ground Cable Specifications
(3) Distribution Board
The branch circuit to supply power to the device requires circuit breakers that meet the following specifications:
• Rated breaking capacity: 15 AT (for a 15 A circuit)
(4) Conditions for the Incoming Power to the Distribution Board
The capacity of electrical current supplied to the distribution board should be larger than that of the breaker operating
current shown in (3) Distribution Board.
(5) Providing Two Power Supply Systems to the Electrical Power Equipment
To build a redundant power supply system, use another system of electrical power equipment to supply power.

Make sure to connect the ground cable. Not connecting the grounded outlet to the
device can cause electric shocks, as well as a cause a failure due to electrical noise.
For easy operation, it is recommended that the distribution board should be installed in the
same room as the device or in an adjacent room.
Ensure that the capacity of incoming current to the distribution board is larger than the
breaker operating current capacity. Otherwise, the breakers cannot operate properly if
there isa problem, which might cause a fire.
Generally, the breaker operating current is larger than the rated current. Check the
specifications of the circuit breaker.
