3Operating Procedures
3.1 Controller and Rectifier
For operation instructions on these units, refer to the following documents.
•Mini Control Unit Instructions: UM1M831ANA
NOTE! The controller’s default “User Name” is "admin" and the default “Password” is “640275”.
•Rectifier Instructions: UM1R481000e3
3.2 Controller Battery Charge Current Limit Feature
Functionality: After a failure of the input source (commercial AC) or when some battery cells are permanently damaged, the current
to the batteries can be quite extensive. To avoid overheating or further damages to the battery, the controller can be programmed to
limit the battery current to a preset level by limiting the charging voltage of the rectifiers. Should the battery current still exceed a
higher preset value, an alarm is issued.
The controller limits the current going to the batteries based on the “Battery Current Limit” set point which is a percentage of the
battery capacity in C10. For example, 0.1C10 would mean 10% of the battery capacity.
Refer to the mini control unit Instructions (UM1M831ANA) to program this feature. Battery charge current is limited to the value set in
the controller, as long as battery voltage is above 47 VDC.
3.3 Local Controls and Indicators

5.2 Controller and Rectifier
For troubleshooting and repair instructions on these units, refer to the following documents.
•Mini Control Unit Instructions: UM1M831ANA
•Rectifier Instructions: UM1R481000e3
5.3 Controller Configuration
If any controller configuration settings were changed, refer to the mini control unit instructions (UM1M831ANA) and save a copy of
the configuration file. This file can be used to restore the controller settings, if required, at a later date.
NOTE! Provided on a USB drive furnished with the system is a controller configuration drawing (C-drawing) and the
controller configuration files loaded into the controller as shipped.
5.4 System Troubleshooting Information
5.4.1 Contact Information
Refer to Section 4154 (provided with your customer documentation) for support contact information.
5.4.2 General
This system is designed for ease in troubleshooting and repair. The various indicators as described in the controller and rectifier
instructions are designed to isolate failure to a specific element. Once the faulty element has been identified, refer to “Replacement
Information” on page 6 and “Replacement Procedures” on page 6.
5.4.3 Troubleshooting Alarm Conditions on the Controller
The controller displays alarm conditions as listed in the “Resolving Alarms” section of the controller’s user manual. Programmable
external alarm relays are also available. Refer to the system installation instructions (IM582138000) and the controller configuration
drawing (C-drawing) supplied with your power system documentation for your alarm relay configurations.
The controller’s Active Alarm and Alarm History submenus allow the user to view alarm details. Refer to the mini control unit
instructions (UM1M831ANA) to access these menus.
5.4.4 Checking the Controller’s Current Limit Point after Adding or Removing a Rectifier
If a rectifier module is added; the respective current limit point in amps will automatically increase to maintain the same percentage.
For example, if the current limit was set to 100% of combined capacity and a rectifier module is added, the new current limit setpoint
will be 100% of the combined capacity including the new rectifier module.
If a rectifier module is removed from the system (and the Rect Comm Fail is cleared), the current limit point will remain unchanged
unless the capacity of the remaining rectifiers is not sufficient to maintain this current limit point. If that happens, the current limit
point will automatically decrease to the maximum (121% of the remaining rectifiers).
It is recommended that the current limit point be checked whenever a rectifier is added to or removed from the power system.
When setting total rectifier current limit, the set point to each rectifier is the total set point divided by the number of rectifiers. For
example, if the system contains three rectifiers and the current limit is set to 30 amps then each rectifier has a current limit set point

Vertiv™ NetSure™ 2100 Series -48 VDC Power System User Manual
Proprietary and Confidential © 2022 Vertiv Group Corp.
6
of 10 amps. If one or more rectifiers are removed or fails it will take several seconds for the individual set points to the remaining
rectifiers to be reset. In the example given, if one rectifier is removed the current limit set point will drop to 20 amps (10 amps times
two remaining rectifiers) until the controller can send updated set points to the remaining rectifiers.
This takes a couple communication cycles (several seconds) after which each rectifier would have a new set point of 15 amps for a
total of 30 amps. The total current limit of the rectifiers should not be set such that the loss of the redundant rectifiers will cause this
temporary set point to drop below the actual maximum expected load. If batteries are used on the rectifier output, the batteries
should support the load until the current limit set points can be re-established due to loss of a rectifier.
Refer to the mini control unit instructions (UM1M831ANA) for a procedure.
5.4.5 Clearing a Rectifier Communications Fail Alarm after Removing a Rectifier
If a rectifier module is removed from the system, a rectifier communications failure alarm is generated. If the rectifier module will not
be replaced, the alarm should be cleared.
Refer to the mini control unit instructions (UM1M831ANA) for a procedure to clear the alarm.
5.4.6 Clearing a Rectifier Lost Alarm
If the controller resets while a rectifier communications fail alarm is active, the rectifier communications fail alarm is replaced with a
rectifier lost alarm.
Refer to the mini control unit instructions (UM1M831ANA) for a procedure to clear the alarm.
5.5 Replacement Information
5.5.1 Replacement Assemblies
When a trouble symptom is localized to a faulty rectifier, controller, or system circuit card; that particular device or circuit card should
be replaced in its entirety. No attempt should be made to troubleshoot or repair individual components on any rectifier, controller, or
