(2) Power cable IDDs must be star-connected to the DC power supply (one to one connection) to reduce the influence of load variations. (3) DC ground The DC ground cable must always be connected to the IDD because no fasten terminal dedicated to SG is provided with the IDD. Therefore, when SG and FG are connected in the system, it is necessary to connect SG and FG at the power supply or to connect SG of the power supply to FG of the system. (4) External operator panel (MP model only) The external operator panel is installed only when required for the system. When connection is not required, leave open the following pins in the external operator panel connector of the IDD : Pins 21, 22 and pins 01 through 08 in CN2 and pins A1 through A12 in CN1.

SCSI cable

See Section 1.3, “Physical Requirements”, and Section 1.4, “Electrical Requirements”, in SCSI

Physical Interface Specifications.

(2)

Power cable

IDDs must be star-connected to the DC power supply (one to one connection) to reduce the

influence of load variations.

(3)

DC ground

The DC ground cable must always be connected to the IDD because no fasten terminal dedicated

to SG is provided with the IDD.

Therefore, when SG and FG are connected in the system, it is

necessary to connect SG and FG at the power supply or to connect SG of the power supply to FG

of the system.

(4)

External operator panel (MP model only)

The external operator panel is installed only when required for the system.

When connection is

not required, leave open the following pins in the external operator panel connector of the IDD :

Pins 21, 22 and pins 01 through 08 in CN2 and pins A1 through A12 in CN1.
