12.4 On/Off control
Fig 12-4 shows typical connection for individual On/Off control of each installed FPS1000 unit. The On/Off
control signal is applied to the DB25 connector located at the rear panel (refer to sec. 10.7.5).
When it is desired to control all the installed units simultaneously, it is possible to connect the On/Off control
as shown in Fig 12-5.

12.5 Output voltage trimming
Refer to Fig 12-6 for output voltage trimming typical application.
12.6 Supervisory signals
Supervisory signals are accessible at the J1-DB25 female connector on the rear panel of the rack.
Fig 12-7 shows a typical connection for FPS1000 unit "A" inside the rack.
Units "B" and "C" connections - Reffer to sec 10.7.5.
12.7 Grounding outputs
Either the positive or negative output terminals can be grounded. To avoid noise problems caused by
common-mode current flowing from the load to ground, it is recommended to ground the output terminal
as close as possible to the power supply's output. Always use two wires to connect the load to the power
supply regardless of how the system is grounded.
