1.3 Safety precautions
The PDU contains hazardous voltages, and hazardous voltages are present regardless of the mode of
operation. Before making any connection(s) to the PDU, ensure that any/all power sources are de-
energized and locked out.
As lethal voltages are present within the PDU during all modes of operation, maintenance shall only be
performed by authorized service personnel.
ABB neither recommends nor knowingly sells this product for use with life support applications or other
FDA designed critical applications.
All wiring should be performed by qualified electricians and in the accordance with local and national
electrical safety codes. Before placing the unit into service, a thorough inspection and supervised start-up
should be performed by a qualified service technician.
This PDU is designed for operation from a three (3) phase, three (3) wire power source. Refer to the
unit’s nameplate for the specific model designation, operating voltage, and input power configuration.
Input over-current protection is to be supplied by the user in accordance with nameplate ratings, in
applications where the PDU has no main breaker.
1.4 Safety considerations
The TruFit™ PDU is designed for commercial applications and should be handled with appropriate care,
following these guidelines:
 Keep surroundings clean and free from excess moisture.
 Do not operate the PDU system close to gas or electric heat sources.
 The system is not intended for outdoor use.
 The operating environment should be maintained within the parameters stated in the manual.
 Keep the cabinet doors closed and locked to ensure proper cooling airflow and to protect personnel
from dangerous voltages inside the unit.
Only authorized service personnel should perform maintenance on or service
the PDU system.
If service or routine maintenance is required:
 Ensure all power is disconnected before performing maintenance.
 Ensure the area around the PDU is clean and uncluttered.
 Observe all DANGER, CAUTION and WARNING notices affixed to the inside and outside of the
equipment.
To provide sufficient isolation protection when working upstream of the PDU,
open the respective source feeder breakers contained within the PDU.
Prescribing to this maintenance method reduces the risk of electric shock
due to backfeed.

3 Startup
3.1 Powerup
3.1.1 Safety checks before energizing system
Prior to energizing the system, the installing electrical contractor should verify the following:
1. Proper phase rotation and safe grounding practices have been exercised.
2. All conductor sizing meets or exceeds conductor sizes as detailed in the guidelines of the current
National Electric Code.
3. All building interface points are terminated onto the system’s interface board (see Section 3.4.6.3).
4. The TruFit™ system’s main input circuit breaker and all subsequent circuit breakers are all in the
“OFF” position.
** DOUBLE CHECK ITEMS 1-4 AFTER THE STEPS ABOVE HAVE BEEN PERFORMED **
3.1.2 Energizing the system
1. The installing electrical contractor should now verify that the input voltage to the unit properly
matches the input voltage rating of the unit as reflected on the system’s identification label (affixed
to the inside of the front door of the unit) and as indicated on the transformer label located on the
top of the high isolation transformer positioned in the rear of the unit.
2. Turn the building’s circuit breaker feeding the TruFit™ product to the “ON” position. The system’s
red Emergency Power Off (EPO) pushbutton should now be illuminated as well as display LCD
screen indicating power is present at the line side of the TruFit™ system main circuit breaker.
3. Energize the TruFit™ product by turning the system’s main input circuit breaker to the “ON”
position.
4. Next, the output voltages from the system should be verified. Identify the output voltage of the
transformer by using a true RMS digital volt-meter. If the output voltage of the transformer is not
the desired voltage, access the system’s 2 1/2% compensation taps. Compensation tap
configurations are clearly marked on the label affixed to the top of the high isolation transformer
itself. The contractor should re-verify the output voltage to determine that the optimum
compensation tap combination is used to achieve an output voltage as close to your output voltage
as possible.
5. The installing contractor should now verify that the Emergency Power Off (EPO) circuit and the
Remote Emergency Power OFF (REPO) circuit (if applicable) are connected and working properly.
6. Now that the emergency power off circuit has been verified and input/output voltages are adjusted
properly, energize the system’s secondary main circuit breakers (if purchased). Next, sequentially
energize the branch circuit breakers to distribute power to your critical load.
 Per NEC Article 645.10, an Emergency Power Off button (EPO) is
required. If this option is not installed on the PDU, a remote EPO must
be installed. See Section 3.4.6.3 for location of connection.
Your TruFit™ system is now distributing power to your connected load. The next sections are dedicated to
assisting you in operating your display/monitoring system. Please take a moment to familiarize yourself
with your TruFit™ product.

3.2 Graphical user interface
The user interface is a touchscreen LCD. It shows all system status as well as providing a means to set
the unit up and control it. This is done through buttons, checkboxes, radio buttons, pull-down menus, and
text entry screens.
The GUI display/control panel displays system status as monitored by the PowerView metering system.
Monitoring details can be found in Section 5.
The GUI display/control panel is surrounded by a ring light, which displays green, yellow or red, depending
on operating status and active alarms, as described in Section 4.3.
Each PDU unit has a User Interface Board (UIB), which is provided for the user's connections.
External monitoring systems, e.g., Building Management Systems, can be used to poll the PDU units using
Modbus RTU (on an RS-485 bus) or Modbus/TCP. Each unit connected in the Modbus network shall be
configured with a unique Modbus ID.
The operation of the display module is based on the Navigation Bar.
