Vertiv™ NetSure™ Control Unit (NCU) User Manual
NOTE!
SOME SYSTEMS REQUIRE CHANGES TO THE NCU CONFIGURATION DURING FINAL TEST BEFORE BEING
SHIPPED. These systems are supplied with a USB memory device that contains a “SettingParam.tar” file as shipped. If
provided, the “SettingParam.tar” file has a seven-digit UIN (Unique Identification Number) preceding the “SettingParam.tar”
filename. The UIN identifies a “SettingParam.tar” file for use with a specific system. This file can be used to restore your
system to the configuration as shipped. Refer to “Reloading a Backed-Up NCU Configuration” on page 48 to reload the
supplied “SettingParam.tar” file.
TO RESTORE THESE SYSTEMS TO THE NCU CONFIGURATION AS SHIPPED, RESTORE DEFAULTS AS DESCRIBED ABOVE; THEN
RELOAD THE SUPPLIED "SETTINGPARAM.TAR" FILE.

NOTE!
The controller does not turn off any relay when the controller is reset/replaced. If the relay is active when the
controller is reset/replaced, it will stay active whether or not the alarm condition still exists. If possible, the alarm condition
should be cleared before the controller is reset/replaced. If the alarm is not cleared, after starting the controller, it may be
necessary to manually trigger an alarm condition to clear all alarm relays.
