Precautions

Read and follow these precautions.

• General precautions:

• Use only properly insulated tools.

• Remove all metallic objects (key chains, glasses, rings, watches, other jewelry, etc.).

• Wear safety glasses.

• Test circuits before touching.

• Lock out and tag circuit breakers/fuses when possible to prevent accidental turn on.

• Be aware of potential hazards before servicing equipment.

• Identify exposed hazardous electrical potentials on connectors, wiring, etc. (note the condition

of these circuits, especially wiring).

• Use care when removing or replacing covers; avoid contacting circuits.

• Use a personal ESD strap when accessing or removing electronic components.

• The equipment must be installed, serviced, and operated only by skilled, qualified personnel who

have the necessary knowledge and practical experience with electrical equipment and who
understand the hazards that can arise when working on this type of equipment.

• Exercise care and follow all safety warnings and practices when servicing this equipment. Hazardous

energy and voltages are present in the unit and on the interface cables that can shock or cause
serious injury.

• Batteries may be connected in parallel with the output of the rectifiers. Turning off the rectifiers will

not necessarily remove power from the bus. Make sure the battery power is also disconnected
and/or follow safety procedures while working on any equipment that contains hazardous
energy/voltage.

• Electricity produces magnetic fields that can affect implanted medical electronic devices, such as

pacemakers. The strength of the magnetic field depends on the amount of current in the circuit, as
well as other conditions (such as number of conductors, placement, and distance from the
conductor). DC power and distribution systems, including batteries, can operate at high current
levels. Personnel with electronic medical devices need to be aware of their restrictions when
working around electricity.

Load Bus Arrangements

A load bus is defined as one or more panels protected by a single circuit breaker or fuse
at the battery plant. Cable from the battery plant is terminated at Load Shunt Bus
Details rated for 800 amperes. (Two 750 kcmil feeder cables are required per shunt for
currents larger than 500 amps per shunt.) 3/8 inch hardware is provided for this
connection. The cabinet may be equipped for 2, 4 or 6 loads. In 2 or 4 load
configurations a bus bar link connects some panels together vertically. The 800 ampere
capacity per load bus applies even if multiple fuse panels are connected together.

When internal return buses are ordered, load return bus details will be located either at
the top or the bottom of the cabinet as shown depending on if a top cable feed or
bottom cable feed was ordered. These may easily be unbolted and moved if the
application requires. 3/8 inch hardware is provided for load return cables.

Note

the application of NO-OX before connection to terminal lugs or other bus bars.

Figure 10 Load Connection Points

Issue 3 June 2012 19

Distribution Panels

Each 28-position distribution panel accepts bullet-style circuit breakers and fuseholders.
Single-pole breakers through 100A, two-pole breakers through 150A, three-pole
breakers through 250A and fuses to 125A may be installed in any position with no
spacing restrictions. Panels come with hinged front doors equipped with plastic slot
fillers. As circuit breakers or fuseholders are installed, un-snap the plastic slot filler and
replace with a circuit breaker or fuseholder. Store the excess plastic slot fillers in the
hardware bin in the back of the cabinet. Note: breakers/fuseholders can only be
installed one way or the front hinged door will not close properly. Each distribution
position has three alarm pin openings. The outer alarm opening is the alarm output.
Alarm pin of protector should insert into this opening. The inner two openings are
provided because some breaker styles have additional pins that require alarm power to
generate the output alarm.

Programming the Meter

VIM1C parameters like shunt size and number of load buses are preconfigured when it is factory
installed in a BDFB. Only customer specific preferences need to be adjusted in the field. As a
replacement or meter upgrade, the factory default settings may need to be adjusted for the
application. Listed below are the configurable parameters and their associated factory defaults
available through the front panel. Following the table are the typical items that need to be
configured or verified in a retrofit or replacement application.

Used to identify the number of individual loads/buses in the BDFB. Factory set from 1-8
depending on BDFB configuration.

Configures meter to display individual monitored bus voltages (voltage), voltages and
currents (volt_curr), or only currents (current). Factory default is Voltage and Current
(volt_curr).

Configures display format used in referencing individual DC loads/buses. Allowable
formats: A1, A, and 1. “A1” identifies loads using an A1, B1; A2, B2; … format. “A”
identifies loads using an A, B, C, D ... format. “1” identifies loads using a 1, 2, 3, 4 …
format. Factor Default is A format.

Used to indicate where the first load in the distribution is located. Allowable configurations
are: top-left, top-right, btm-left (bott om -l e ft), btm-right (bottom-right). Every monitored shunt
is considered a load. Factory default is determined by BDFB configuration.

Used to define the current rating of the shunt in the load bus. All shunts in the load must be
of the same size. A 50mV shunt is assumed. Allowable range is 1-4000A. The factory
default is 1500A in the BDFB.

A single configuration for all panels/buses that allows a temporary Over Load event to be
latched. Factory default is “Disabled”.

Displays the load value as one combined sum by adding up all shunts in the system and
presenting it as values for a single load. Factory default is disabled.

Indicates if the load is available or in use. Allowable configurations are “installed” and “not
installed”. “Installed” loads imply that the load is in use. “Not Installed” loads imply that the
load may be present, but it is not in use. Information obtained from the load should not be
relevant. Factor default is set to be “installed”.

The Power Loss (PL) alarm is triggered upon loss of the primary DC or when the
individual’s panels’ DC input has reached the configured low voltage threshold. This Power
Loss voltage threshold is configurable between 40.00-60.00V. Factory default is 40.00V.

The Power Overload Type defines whether the smart meter is to treat the Overload alarm
event for a “Single Bus” or for a “Redundant Bus” configuration. The “Single Bus”
configuration is based on straight Overload threshold being exceeded. The “Redundant
Bus” configuration causes the VIM1 to sum the two respective left and right load shunt
measurements and compare it to the individual overload thresholds configured for the each
of the respective panels in the pairing. The lowest Overload value threshold configured for
the Redundant loads shall take priority and be used in the comparison. Once the
“Redundant Bus” measurement exceeds this threshold, the controller asserts the Over
Load (OVL) alarm. Factor default is “Single Bus” configuration”.

The Load Overload (OVL) alarm event is triggered when any measured panel currents
exceed their respective configured thresholds. These OVL thresholds can be configured
from 1-4000A. Factory default is 800A.

An Overload Delay can be set to prevent nuisance alarms. This delay is configurable
between 0-300 seconds. Factory default is 0 seconds.

Alarm Connections and ABS Power

At the top of the cabinet is a Customer Interface Board for connecting Output Alarms
and Alarm Battery Supply (ABS) to redundantly power the alarms and the VIM1C meter.
The VIM1C receives redundant power from panels 1 and 2 as well as an external ABS
connection, so the ABS connection is not mandatory for proper operation but some
customers require its use. A Return connection is required for operation of the meter
and alarms. The Return connection on the Customer Interface Board is factory wired
when internal return buses are ordered, otherwise it must be field wired to the external
return bus. Alarm Outputs consist of one form-C contact for power loss, one form-C for
current overload and one form-C contact for fuse/breaker alarms (Note: there are two
connection points for FAJ/CB but they are connected to the same form-C contact).
Contacts are rated for 60V, 1/2A. Maximum wire size to the terminal blocks is 12 gage.

Discharge Return Bus Options

Discharge return bus options for terminating fuse or circuit breaker return leads may
either be internally mounted in the cabinet or externally mounted outside the
distribution bay on a cable rack.

Internal

The internal discharge return bus bar option terminates return cables from the battery
plant at the top (or bottom) of the cabinet as shown in Figure 12. There is a left-side bus
that interconnects to return bars mounted on the three left mounted fuse or circuit
breaker panels and a right-side bus for the right mounted panels. The bus at the top of
the cabinet is designed for terminating six 3/8 inch double-hole terminal lugs on 1 inch
centers with a tongue width up to 1.7 inches wide. Each panel mounted discharge
return bus is designed for terminating up to 2 gage cable with 1/4 inch double-hole
terminal lugs on 5/8 inch centers.

The advantage of internal returns is that load leads are paired at the fuse or circuit
breaker and eliminates the need for identification tags on each return lead. The
drawback to this cabling scheme is that you are limited to 1200 amps per side so for
multi-load BDFB’s requiring from 1200A-2400A capacity per side requires that input
returns must be located at the top and bottom of the cabinet with returns from the
battery plant split between the top and bottom bus bars. A second concern is the
potential cable congestion resulting from twice the number of leads in the distribution
bay. For these reasons, the internal discharge return option is recommended only for
applications with smaller ultimate capacities. For most applications, the external return
bus option is recommended.

External

The external discharge return bus bar options are shown in Figure 19 and Figure 20. The
external bus is mounted on a standard 15 or 20 inch ladder type cable rack. ED83019-50
Group 13 (150021156) and Group 13A (150021157) are rated for 2400 amperes of
current. Option 150021156 provides the first bus bar and the cable rack mounting
hardware. Option 150021157 provides a bus bar, the connecting bus bar and insulating
standoffs for stacking additional tiers as required. Refer to ED83019-50 drawing for
other ground bar options.

Adding/Moving Load Shunt Bus Details

Sometimes it may be necessary to reconfigure a BDFB in the field. Two common
changes are converting two load BDFB’s from top feed configurations to bottom feed
configurations and changing from a 2-load to a 4 or 6-load BDFB. Additional Load Shunt
Bus Kits as shown on Figure 10 may be purchased separately.

Converting Top-Feed to Bottom-Feed

The following steps describe how to convert a top-feed cabinet to a bottom-feed
cabinet. Reverse this procedure to convert a bottom-feed to a top-feed cabinet.

1. Disconnect wires from the shunts on the load shunt assembly. Note the wire

colors and location. These same colors are used when moving the shunts from
panel position 1 to panel 5 position and panel position 2 to panel position 6. The
solid color (blue or slate) is closest to the input cables.

2. Disconnect the hardware securing the shunt assembly at the top of the cabinet.

3. Remove 6-32 screw securing shunt wires to the charge bus bar at the bottom of

the cabinet where the shunt assembly will be placed.

4. Relocate load shunt assembly and mount it in the bottom of the cabinet.

5. Connect shunt wires in same location and color as in previous location.

6. Connect shunt wires to the charge bus bar at the top of the cabinet where the

shunt assembly was removed using same 6-32 screw.

7. Move the internal return bus bar from the top to the bottom of the cabinet.

Note: Internal return bus bars may not be present.

8. The VIM1 meter needs to be reconfigured. Navigate to Menu ►Lo ad Paramet ers

►First Load

lower-right depending on which side you want to be side A and side B.

9. Relabeling might also be required as discussed in the Panel Positions and

Labeling section.

Converting from 2-Load to 4 or 6-Load

This requires that new load shunt bus kits be added to existing panels in the cabinet and
linking bus bars between panels be removed or “split” to create the additional loads.
The following steps describe this procedure.

Caution: Live potentials are present within a working BDFB/ BDCBB cabinet! Take

proper precautions to insulate all tools and prohibit any live surface from contacting

framework or any other grounded surface.

Note: If splitting existing loads within the BDFB/BDCBB, the load shunt assembly

will be at a live potential as soon as it comes into contact with a distribution panel
bus and must not be allowed to contact framework or any grounded surface during
or following this step!

1. Remove 6-32 screw securing shunt wires to the charge bus bar where the new

load shunt bus assembly will be installed. Note color of shunt wires at each
position.

2. Install load shunt bus assembly to the charge bus as shown in Figure 22. Connect

(2) red glastic standoffs to panel. Attach shunt detail to panels charge bus with
5/16 hardware provided and ½” socket (Torque to 135 in-lb) and attach to
standoffs with 1/4-20 screws provided and 7/16” socket (Torque to 65 in-lb).

3. Connect shunt wires to shunt. There should be a solid color like Blue, Orange,

Gray or Brown and a striped color like White-Blue, White-Orange, White-Gray or
White-Brown. Attach solid color to back connection (it is connected to input
bus). Attach striped color to front connection (it is connected to panels charge
bus).

4. Remove Bus Bar Straps to “split off” these panels as individual load buses.

Remove 5/16” hardware with ½” socket. Store these links in hardware bin in
back of cabinet.

5. The VIM1 meter needs to be reconfigured. Navigate to

Menu ►Load Parameters ►Number of Loads and set the number of load shunts

in the BDFB.

6. Relabeling might also be required as discussed in Section 8. Stamp or Label new

load designations on the labels.
