4.5 Controller
NCU (NetSure Control Unit) Controller, P/N 1M830BNA
•Each 58870530036 Rectifier System accepts one (1) NCU Controller; Model M830B, Spec. No. 1M830BNA.
•Factory programmed with the configuration file specified when ordered.
NOTE! The controller is provided with the factory default configuration unless otherwise specified.
NOTE! For custom NCU configurations, contact Vertiv.
•Refer to the NCU Controller Instructions (UM1M830BNA) for more information.
•One (1) controller per system is required.
•Ordering an NCU for replacing an NCU or as a spare NCU.
If the NCU is to be used as a replacement in a specific system it should be ordered with the same configuration file as the
original NCU controller. This is identified by a six digit number. If the controller part number ends with a six digit number, for
example, 1M830BNA559242, the configuration file number is the last six characters. If the part number does not have these
characters, the configuration file number can be found on the controller nameplate – “Programmed with Configuration File
######”. The controller may also have a Unique Identification Number (UIN). This number indicates that certain
parameters were set at the factory to match the controller to the options selected with the power plant (such as low voltage
disconnect, load and battery shunt ratings, etc.). If the controller has a UIN, the plant will have shipped with a USB drive
labelled with the UIN. The UIN label may also be located near the controller slot in the system. If the controller has a UIN,

provide this UIN number, along with the configuration number, when ordering so that the new controller will match that of the
original controller shipped with the system. The user manual provided with the controller provides instructions for replacing
and programming the controller. It is important to follow these instructions carefully. The user manual also provides
instructions for saving certain controller files that are created when changes are made to the system after leaving the factory.
These files can be programmed into the replacement controller so it can match the latest saved state of the original
controller.
If the NCU is being ordered as a spare part for any of a group of power plants, the same procedure can be followed. If the
replacement controller’s configuration does not match that of the original controller, the original files can be retrieved from
the USB drive shipped with the plant, if available. If the USB drive is not available, contact the factory or technical assistance
center to obtain a copy of the original configuration file (all package) so it can be programmed into the new controller.

Procedure
1. For 23” mounting, attached the 23” mounting bracket adapter plates to the standard 19” mounting brackets.
2. Position the system in the relay rack or cabinet equipment rack.
3. Secure the system to the relay rack or cabinet equipment rack using hardware as shown in Figure 6.1 (see Figure 6.1 for
recommended torque). Use grounding washers as indicated in Figure 6.1.
NOTE! Install (orient) the ground washers so the teeth dig into the mounting angles for a secure ground connection.
NOTE! Compliance with Telcordia GR-1089-CORE requires that prior to mounting the system to the equipment rack:
•All paint must be removed from the front surface of each equipment rack rail where it mates with a shelf-mounting
bracket, so that good metal-to-metal contact can be established between the shelf and rack.
•The shelf-to-rack mating surfaces must be cleaned.
•Electrical anti-oxidizing compound must be applied to the shelf-to-rack mating surfaces.

7.3 Frame Grounding Connection
For grounding requirements, refer to the current edition of the American National Standards Institute (ANSI) approved National Fire
Protection Association's (NFPA) National Electrical Code (NEC), applicable local codes, and your specific site requirements.
NOTE! The DC return connection to this system can remain isolated from system frame and chassis (DC-I).
NOTE! This system is suitable for installation as part of the Common Bonding Network (CBN).
Procedure
1. The frame grounding connection to the shelf is made by using grounding washers with the mounting hardware used to
secure the shelf to the relay rack or cabinet. Refer to “Securing the System to a Relay Rack or a Cabinet Equipment Rack (if
required)” on page 10. Ensure that the relay rack or cabinet is properly grounded.
NOTE! An 8-32 frame ground stud is located on the rear of the system. Provide a grounding lead to this connection point, if
required. Refer to
Figure 7.1 for location.
Figure 7.1 Bulk Output Rectifier System Frame Grounding Connection Points
7.4 NCU Controller Ethernet Connection (if required)
The NCU Controller provides a Web Interface via an Ethernet connection to a TCP/IP network. This interface can be accessed locally
on a computer or remotely through a network. An RJ-45 10BaseT jack is provided on the front of the NCU for connection into a
customer's network. This jack has a standard Ethernet pin configuration scheme, twisted pair. Refer to Figure 7.2 for location and
Table 7.1 for pin outs. Use shielded Ethernet cable (grounded at both ends). Note that the NCU RJ-45 jack is connected to chassis
ground. Refer to the NCU Instructions (UM1M830BNA) for operational details.
NOTE! You can access the Web pages of the power system locally by using a "crossover" or “straight” cable connected
directly between your PC and the NCU.

WARNING! The intra-building port(s) of the equipment or subassembly is suitable for connection to intra-building or
unexposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST NOT be metallically
connected to the interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building
interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP
cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to
OSP wiring.
The intra-building port (RJ-45) of the equipment or subassembly must use shielded intra-building cabling/wiring that is
grounded at both ends.
