3. Do not attempt to work on this equipment if it is, or has been, exposed to a high moisture
condition. It is recommended the equipment be returned to ABB POWER to be properly tested.
Working on this equipment during a high moisture condition subjects the user to electrical shock
that may cause serious injury or death.
Pas la tentative pour traiter cet équipement si c'est, ou a été, exposé à une haute condition
d'humidité. Il est recommandé l'équipement s'est retourné à ABB POWER deux être convenablement
essayé. Traiter cet équipement pendant une haute condition d'humidité expose l'utilisateur au choc
électrique qui peut causer la blessure ou la mort Sérieuse
4. Use of an attachment other than one approved by ABB POWER will void any and all warranties,
implied or other, and will increase risk of fire, or may possibly cause electrical shock, injury, or death
to personnel
L'usage d'un attachement autrement qu'un approuvé par ABB POWER annulera n'importe quel et
toutes garanties, implicites ou autres, et augmentera le risque de feu, ou probablement peut causer
le choc électrique, la blessure, ou la mort au personnel.
5. Do not operate this equipment if it has been dropped or otherwise damaged. Trying to operate
this equipment if it has been damaged subjects yourself or others to electrical shock that may cause
serious injury or death.
L'usage d'un attachement autrement qu'un approuvé par ABB POWER annulera n'importe quel et
toutes garanties, implicites ou autres, et augmentera le risque de feu, ou probablement peut causer
le choc électrique, la blessure, ou la mort au personnel
6. Before you proceed, ensure the input source is not live and the input circuit breaker(s)/fuse(s) has
been tripped or removed. If these procedures have not been followed and the input/output power is
live, serious personnel injury or death may occur.

7. A rack/shelf may contain several operating systems. If there is another system in the general area
you want to install this system, be cautious of any exposed connectors or wires and, with
permission, remove power to the other systems. Failure to take the necessary safety precautions
subjects the installer or maintenance personnel to severe electrical shock that may cause serious
injury or death.

1: Theory of Operation
The maintenance bypass panel (MBS) is designed to be used with the ABB POWER 827E inverter
plant. The main purpose of the MBS is to allow an AC load to be switched from its primary source
(Inverters) to an alternate source (commercial AC) and back to the primary source (Inverters) again.
This may be required, for example, when doing maintenance or upgrades to the Inverter Plant. The
transfer is done with a front panel mounted switch. The Inverter source and AC Line source are not
phase locked and the transfer is asynchronous, i.e., it occurs at random phase. For more information,
refer to schematic 4391036SD and 4391036SD-1 attached to the rear of this document.
A manual front panel “BYPASS” switch is used to select the load source. The “INVENTER.” mode
selects the Inverter source and is the normal state. The unit is said to be in “BYPASS” mode when the
“UTILITY” (commercial AC) source is selected. There are front panel LEDs to indicate if the
“INVERTER” and “commercial AC” voltages are present, and to indicate if the unit is in BYPASS mode.
While the INVENTER and AC LEDs indicate the presence of those source voltages, they do not prevent
the load transfer from occurring. It is the operator’s responsibility to know if the source that is being
transferred to is an energized source.
An alternate purpose of the MBS is to collect alarms from the inverter shelves and to extend these
alarms to the plant monitor. The status of the consolidated alarms is indicated by the upper three
LEDs on the front panel. Any Major alarm will light the Major LED and extend a form C transfer to the
plant monitor via a terminal block on the rear panel (see system schematic for details). A single Minor
alarm extend a minor alarm, however, two or more Minor alarms will generate a Major alarm and
retire (turn off) the Minor alarm. A Capacity alarm is an indication that an inverter shelf has exceeded
its programmed and/or equipped capacity. This alarm may be used as a prompt to add more inverter
capacity (i.e. shelves and modules). The load sharing capabilities of the 827E inverters will typically
cause multiple shelves to provide a Capacity Alarm at the same time, if configured and equipped
similarly. The Minor and Capacity alarms are extended to the plant monitor as form C transfers.
NOTE: The MBS is powered by a -48VDC battery input at the rear. If this input is not present, there
will be no LEDs lit on the front panel.

3: System Installation
FIGURE 3-1: TYPICAL MAINTENANCE BYPASS PANEL INSTALLATION
3.1 General
NOTE: ABB POWER recommends that the Maintenance Bypass Panel is installed above the top-most
827E Inverter Shelf (refer to Figure 3-1). ABB POWER recommends leaving one rack mounting space
between the MBS and the first Inverter shelf as well as from Inverter shelf to inverter shelf to allow air
flow between units for proper heat dissipation (refer to Figure 3-1).
CABLING:
A. Remove the maintenance bypass panel from the shipping container.
B. Install the panel as follows:
1. Ensure there is proper clearance in the rack to install the maintenance bypass panel.
2. Put the panel into position and secure with the screws located at each outside corner (four screws total).
NOTE: The maintenance bypass panel is designed to be either flush or mid mounted.

3.2 Utility (Commercial AC) Input Connections
WARNING: All power should remain in the OFF position for the entire installation section. Serious
injury or death could occur from live AC circuits. ABB POWER recommends that Licensed
Electricians wire all AC connections into the MBS.
A. Remove the rear cover to access the AC input connections. Refer to Figure 3-3.
B. Connect the commercial 120VAC power to the input connections as shown in Figure 3-3. Each input connection
is made via a compression screw. Maximum size cable is 350 MCM.
C. Ensure that commercial AC power is protected from the customer side of the bypass panel.
D. If used with an 827E Inverter Plant, a circuit breaker is provided in the inverter shelf to provide over current
protection or disconnect means between the inverter and MBS.
E. Over current protection for Commercial AC fed to the MBS is to be provided by the customer per the National
Electrical Code
NOTE: The NEC dictates that Commercial AC will have the Neutral strapped to ground. No
separately derived system (see NEC Article 100 for definition).

perform the maintenance bypass panel input connections. Serious injury or death could occur from
live AC circuits.
A. With the rear cover still removed, connect the output power from the inverter system to the
inverter input connections on the maintenance bypass panel as shown in Figure 3-4. Each input
connection is made via a compression screw. Maximum size cable is 6 GA.

beginning to perform the load connections from the maintenance bypass panel. Serious injury or
death could occur from live AC circuits.
A. With the rear cover still removed, connect the LOAD (output power) from the maintenance
bypass panel to the load connections. Refer to Figure 3-5. Each LOAD output connection is made
via a compression screw. Maximum size cable is 350 MCM.
