PRE-INSTALLATION REVIEW
PROPER INSTALLATION OF THE SERIES DPB BUSWAY IS
ESSENTIAL TO THE BUSWAY OPERATION.
Before installing the busway:
1) Conduct an insulation resistance test on each busway device to check for possible
damage during shipment or storage. Ensure the phase-to-phase, phase-to-neutral,
and phase-to-ground isolation.
2) Confirm that the ambient temperature range is within acceptable limits –10°C through +40°C.
If not, please consult the factory for possible de-rating.
3) Ensure that there is sufficient clearance from the walls, ceilings, and load devices.
4) Ensure that the factory-manufactured mounting supports will conform to the recommended
spacing guidelines as detailed in the section titled "Mounting the Busrail".
5) Ensure that all splice connections, end feed units, and tap off boxes will be accessible after
installation.
6) After determining the clearances and the mounting method (vertical or horizontal) for the busway
system, level and align the end feeds and busrails before the final tightening and alignment of all
supporting members.
7) Align the busbar ends of adjoining sections, verifying proper busbar alignment, phasing,
and spacing.
8) Verify that the incoming system phasing, and voltage match the busway system phasing and
rated voltage.

BUSWAY SYSTEM MOUNTING
SPECIFIED AND SAFE OPERATION OF THE SERIES DPB BUSWAY IS DEPENDENT ON ITS
PROPER INSTALLATION. MISALIGNMENT OF THE BUSWAY COMPONENTS, (END FEEDS,
BUS RAILS, AND SPLICES) WILL COMPROMISE ITS PERFORMANCE.
1) End Feed enclosures must be securely mounted so that they are completely level (side-to-side and front-to-back).
2) Bus Rails must be securely installed so that they are level and completely aligned to the End Feed enclosures and with
adjoining Bus Rail sections.
3) When each Busway run is properly supported / mounted, leveled , and aligned, all Splices must be verified to be
"un-cammed" (not actuated with Cam Actuator Tool).
4) The Splice units must be able to move freely and fully into both sections of adjoining sections of bus before the Splices can
be "cammed" (actuated).
5) Once the free movement of the Splice units is verified, the Splice can be actuated. The installation of Dowel Pins completes
the correct installation of the Splices.

MAINTENANCE
Series DPB Bus Systems™ require only nominal maintenance. Inspect the busway annually or after any short circuit or
ground fault. Perform the following maintenance procedures:
Carefully inspect all the system. Verify that all Splice Cams (See Figure 8 (160-250A) and Figure 15 (400A)) and are properly
installed and in the locked position. Using a thermal scanning device to record the thermal rise of each termination in each end
feed (See Figure 17 (Standard) and 18 (BCMS)). Record this information for comparison for year over year reviews. Changes in
excess of 5°C should be inspected more carefully; however the monitoring of more than 5 degrees could be due to change on
the loads and not the performance of the busway components.
Check the torque on all power connections using a torque wrench. The tightening torque is specified on the label found in
the End Feed Box (See Figures 17 & 18).
If any busrails, splices, end feed terminations or tap off box contacts are badly discolored, corroded or pitted the devices
must be replaced with new devices.
Ensure that all mechanisms and mechanical interlocks are in satisfactory operational condition.
Check the insulation resistance before re-energizing the busway. Keep a permanent record of resistance readings. Conduct
the insulation resistance test according to the section "Before Enegizing the Busway Checklist".
Energize the equipment again following the instructions in the section "Energizing the Busway System".
After performing all the above inspections and necessary repairs, it may be desirable to perform an infrared temperature
test on all the electrical connections. Conduct this test after the busway is re-energized and reaches a stabilized operating
temperature.
For additional maintenance services please see Appendix H: Service.

SYSTEM DESCRIPTION
This monitoring system is designed for use with the GE Series DPB Busway to provide detailed power parameter information
for the busway input feeders (End Feed Boxes) and branch circuits of the power distribution boxes (Tap Off Boxes). The system
consists of a Communications Hub module located on the End Feed Box which can acquire power information from the
busway input feeders and the branch circuits of Tap Off Boxes equipped with the Branch Circuit Monitoring System (BCMS). The
system is capable of monitoring the power infrastructures of Mission Critical, Industrial and Commercial facilities.
The Series DPB Busway busrail is equipped with an integrated communication cable inside a channel along the bottom of
the rail section. Communication connectors (see Figure 22) are distributed equally along the span of a bus rail to enable
interconnection to each Tap Off Box.. This allows a BCMS-equipped Tap Off Box to communicate with the Input PM /
Accumulator PCBs of the communication hub via a communication receptacle and the interface cable. (see Figure 22 Series DPB Branch Circuit Monitoring System Overview)
Information collected by the Input PM / Accumulator is outputted via Modbus™ RTU through a serial port which can be
routed to a local display as well as via an Ethernet gateway and/or to a customer-supplied monitoring system.
There are two different levels of firmware available – BCMS Basic -Current only, and BCMS Plus – Current Plus Voltage.
See Appendix A, TAP OFF BOX MONITORING SPECIFICATIONS, and Appendix B, END FEED (INPUT PM BOARD) MONITORING
SPECIFICATIONS.

COMMUNICATIONS
The Series DPB Busway BCMS is capable of providing remote communications information in four-wire or two-wire
serial configurations via Modbus™ RTU protocol. It is always suggested to use a shielded twisted pair cable for the
communications interface.
The standard communication setup is through RS422/RS485, four-wire interface with the Tx and Rx on separate pairs due to
the ability to have increased speed on the communications with the Tx and Rx separated. However, it is possible to connect
the Remote Communications to a two-wire network.
The default communications parameters for the interface are 9600 baud, 8 bit, even parity, and 1 stop bit.
There are two different levels of firmware available – BCMS Basic -Current only, and BCMS Plus – Current Plus Voltage.
See Appendix A: TAP OFF BOX MONITORING SPECIFICATIONS, and Appendix B: END FEED (INPUT PM BOARD) MONITORING
SPECIFICATIONS.

CONNECTING THE END FEED BOX TO LOCAL DISPLAYS OR BMS / DCIM SOLUTIONS
Practical operational limits of Modbus are thirty-two devices on a chain which means thirty-two Accumulators can be
connected together. Each device has its own address that limits the number of Accumulators you can have on any Modbus
chain.
There are two communications ports on the Accumulator Board in the End Feed Box for customer communications, J5 and
J6. They are both in parallel, so the End Feeds can be connected in a Modbus daisy chain up to the limits detailed above. The
first port (J6) is dedicated to supplying data to an upstream device acquiring the information. The second port (J5) is used to
link additional acquisition circuit boards to allow a single communications port for multiple boards. Refer to Figure 38 for the
location of the serial port terminal blocks. Be sure to observe polarities and connection points marked on the circuit board
when connecting to the serial port.
The Input Power Monitoring Board in the End Feed and the iBus Board in the Tap Off Boxes have the capability to monitor
multiple sources. The End Feed can monitor two independent three phase sources so designed for a dual bus End Feed.
The iBus Board can monitor 6 currents, two of each phase.
The USB communications port is reserved for factory programming and customization of module parameters. Consult the
External Interface Manual for details.
RS 485 FOUR-WIRE CONNECTION
The four-wire configuration is connected as shown
in Figure 41. When daisy chaining additional
accumulator boards, the output from the first
board (J5) is connected to the input of the second
board (J6). The output going to the serial port of the
external acquisition device, i.e. Modbus™ gateway,
is always connected to J5 of the last board in the
series of boards.
Note(s): Up to 18 boards may be connected on one
string. Jumpers on J9 and J10 must be removed.
If you require a Ground connection, then you
can hook up the Ground connection, but it is not
required.

In the main part of the window is where the connected devices are shown� In Figure 40 there is one “INP PM” and
two “IBUS” boards� INP PM is short for Input Power Monitor, which is the monitoring for the End Feed Box� IBUS is the
monitoring in the Tap Off boxes� Each device has a Unique Identification Number� This number is shown after the ID tag�
Next is the Modbus address for the device� The Comm: Good/Bad indicates if the Accumulator board is communicating
with the device�
It is important when you setup up the busway to know which box is which� Since all the devices are on a bus, it is
impossible to know one from another� It is recommended that you plug them in one at a time� This will allow you to put
them in the order you desire� Each device has a unique identification number, so once the devices are known, they will
remain in the order you put them in� When a device is found, it will be placed in the next available address shown by “No Device”, not necessarily at the end of the list�
Figure 46 image shows some more options when setting up the devices:
Figure 46 - BCMS Setup Tab Detail
In Figure 41 we added two more devices� The second device is a reserved spot� The fourth device is a “No Device” or free
device� If another device were added it would be placed in the fourth spot, since the second is reserved� If there were
not free devices, it would be added to the end of the list�
Note: You can have a maximum of 32 devices connected to an Accumulator. This includes free or reserved devices.
The following are a list of the buttons on the right which are used to set up the devices in the list�
Update – This button will get the latest update from the Accumulator� There is a check box under it, when if checked, will
automatically update the data every two seconds�
Find Device – This will go out on the bus and search for new devices� The is done automatically every thirty seconds, but
during setup this will find them faster if needed�
Add – This will Add a reserved device� If you know you will be adding more Tap Off Boxes in the future, or want to leave a
gap for another reason, you can add a reserved spot� No new device will be added in this address� If you want to remove
the reserve, you can use the remove feature�
Remove – To use Remove you must use the check boxes beside the device you wish to remove� This will remove the
device from the list, and put a “No Device” in its place� If you remove the last device on the list it will not add a no device�
It will remove the device all together�
Swap – To use Swap you must use the check two boxes beside the devices you wish to swap� It swaps the locations and
addresses of the two devices�
Reserve – To use Reserve you must use the check box beside the device you wish to reserve� Only a “No Device” spot can
be reserved� This will reserve the spot so new devices will not use this spot� It can be un-reserved by using the remove
on the reserved spot�
Insert – To use Insert you must use the check box beside the device you wish to insert� Insert will insert a “No device”
spot before the selected item� Note: this will change the addresses of every device including and after the checked box�

iBus device you wish to find� The “Selected On“ will turn the led on the box on solid for the allotted time in the box below
(in minutes)� The “All Off will turn all the lights back to their current state� Blinking for alarm and off for no alarm�
Default – This will Default the board� Defaulting the board will remove all the setup and convert back to a default state�
You will lose all the Modbus setup, device setup and locations� This is not recommended unless you are moving or
reconfiguring the entire busway�
COMMON PROCEDURES
Removing a Tap Off Box:
If you wish to remove a Tap Off Box you must physically disconnect the Communications Cable from the Tap Off Box and
Busrail Connector� Use “Remove” to remove it from the list� It should now be a “No Device” and the Accumulator will not
look for it anymore� If you do not plan to use this location anymore, you may want to use the “Reserve” and reserve this
spot so any new boxes will be added to the end and not the spot where this box was�
Replacing a Tap Off Box:
If you wish to replace a Tap Off Box and put a new one in its place you must disconnect the old Tap Off Box - see section
Tap Off Box Mounting� Use “Remove” to remove it from the list� Install the new Tap Off Box - see section Tap Off Box
Mounting� As long as it is the first “No Device” in the list is where you want it, it will be added back to the same address�
If not, use the “Swap” command to move it to the previous location�
Adding a Tap Off Box:
If you wish to add a Tap Off Box in the first “No Device” spot or at the end, install the new Tap Off Box - see section Tap
Off Box Mounting� Connect the Communications Cable to the Tap Off Box and and an available Busrail Communications
Connector� If you wish to add it to a reserved spot, you will need to remove the reserved by using the “Remove”
command before installation�

The GE Service Department is proud to provide support for its broad range of power quality products. Our commitment to
servicing these products begins with our START UP service, and continues with our factory Warranty and is continuously
maintained through our Preventative Maintenance Contracts.
GE’s STANDARD WARRANTY
GE’s Standard Warranty is good for all products for 18 months following shipment or 12 months after
START UP, whichever comes first. After the warranty period is over, customer is on Time & Material basis
unless a Preventative Maintenance contract is in effect.
GE START UP is recommended for all Series DPB Bus purchased, and is a sure way of getting your power quality
equipment up and running as you need it. By following our standard START UP procedures, you can be assured that
you power quality equipment will perform to your requirements. Some of the features and benefits are:
One Week Normal Business Hours
(M-F 8AM-5PM)– U.S.
One Week Overtime Business Hours
(M-F 5PM-8AM)– U.S.
TRAINING
GE Training is recommended for every installation and is an optional service that can be provided as an
introduction to the Series DPB Bus. The training class will encompass installation, configuration of BCMS and
maintenance of the Series DPB Bus in a classroom setting and hands on field demonstrations.
EXTENDED WARRANTY
GE extended warranty program provides several benefits for the Series DPB Bus.
U.S. – Full Coverage of Parts and Labor; 24 hour phone support; preferred customer rates
International – Parts Only Coverage; 24 hour phone support; preferred customer rates
