power consumption of the subrack cannot be more than 1100 W. Therefore, it is recommended that you select
fuses that support a maximum current of 32 A for the power supply facility.
When grounding the subrack, connect the ground bolt on the subrack to the ground point on the column inside
the cabinet. The subrack then is connected to the external ground bar through the PGND cable on the top of the
cabinet.
