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.
