1.2 Safety rules
Save these instructions!
The power distribution unit operates with high currents and voltages. The properly installed system is
grounded to earth and IP 20 rated against electrical shock and foreign objects when all dead fronts are in
place. Installation and service must be performed by a manufacturer’s qualified technicians or a certified
service partner.
General
- Move the PDU in an upright position in its original package to the final destination room.
To lift the cabinets, use a forklift or lifting belts with spreader bars.
- Check for sufficient floor and elevator loading capacity.
- Check the integrity of the PDU equipment carefully.
If you notice visible damage, do not install or start the PDU.
Contact your ABB Service Center immediately.
- WARNING! RISK OF ELECTRICAL SHOCK!
Do not remove covers, there are no user serviceable parts inside.
This should be performed by qualified service personnel.
- This PDU contains potentially hazardous voltages.
- End user must follow applicable regional occupational safety codes/regulations during installation,
operation and equipment maintenance. This may require additional field marking or labelling defining
appropriate level of PPE (Personal Protection Equipment) to reduce the risk of Arc-flash related injuries.
Contact our ABB Service Center for product specific information.

Installation
- This PDU must be installed and connected only by trained personnel.
- Verify accurately during Commissioning and Maintenance of the PDU, for the following:
Damaged components, squeezed wires and cables, or not correctly inserted plugs.
- After removing the sidewalls of the PDU, make sure that all earth connections when reassembling, are
correctly reattached.
- This PDU is intended for use in a controlled indoor environment free of conductive contaminants and
protected against animal intrusion.
- WARNING! HIGH LEAKAGE CURRENT TO GROUND:
Ground connection is essential before connecting to AC input!
- Switching OFF the Unit does not isolate the PDU from the Utility.
- Do not install the PDU in an excessively humid environment or near water.
- Avoid spilling liquids on or dropping any foreign object into the PDU.
- The Unit must be placed in a sufficiently ventilated area; the ambient temperature should not exceed
104F (40°C).
- It is important that air can move freely around and through the Unit. Do not block the air vents.
- Avoid locations in direct sunlight or near heat sources.
Storage
- Store the PDU in a dry location; storage temperature must be within -13°F (-25°C) to 131°F (+55C).

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.
