(2) 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)
(3) 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 (2) Distribution Board.
(4) Providing Two Power Supply Systems to the Electrical Power Equipment
Using the optional DC power supply cable, two power supply systems can be connected and used.
For the DC power models, make sure to connect the ground cable. Not connecting the
grounded outlet to the device can cause electric shocks, as well as cause a failure due
to electrical noise.
For easy operation, it is recommended that the distribution board 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 should be larger
than the breaker operating current capacity. Otherwise, the breakers cannot operate
properly in case of trouble, which may cause a fire.
Generally, the breaker operating current is larger than the rated current. Check the
specifications of the circuit breaker.
