Jumper Settings On The System Interface Circuit Card - Vertiv NetSure 7100 Installation Manual

4.2 Jumper Settings on the System Interface Circuit Card

Perform the following procedures to verify the factory settings and/or make the required settings per your site requirements. These
procedures can also be used to make adjustments on a replacement circuit card.
Controller Power Option
This option allows the controller to remain powered if a battery LVD contactor is furnished and it opens. The controller is powered
from the internal "system" bus. Rectifiers and battery are connected to this "system" bus, so the controller is powered both by the
rectifiers and by the battery. A jumper option allows the controller to be powered from the "system side" of a battery LVD contactor
(if furnished) or the "battery side" of a battery LVD contactor (if furnished). Refer to Figure 4.2 for circuit card location and jumper
location.
•
Jumper in "No Battery Power" Position: The controller is powered from the "system side" of a battery LVD contactor (if
furnished). Note if a battery LVD contactor is not furnished, the controller is powered by both rectifiers and battery. If a
battery LVD contactor is furnished and opens, the controller is powered by the rectifiers (if functional).
If you lose AC power and your battery LVD contactor opens, the controller will shut down.
•
Jumper in "Battery Power" Position: The controller is powered from the "battery side" of a battery LVD contactor (if
furnished). Note if a battery LVD contactor is not furnished, the controller is powered by both rectifiers and battery. If a
battery LVD contactor is furnished and opens, the controller is powered by the battery and the battery will drain. The
controller's power consumption is 5W.
If you lose AC power and your battery LVD contactor opens, the controller will continue to operate.
