Safety Considerations
The UPS enclosures are designed for industrial or computer room applications,
and contain safety shields behind the doors. However, the UPS is a sophisticated
power system and should be handled with appropriate care, following these
guidelines:
• Keep surroundings clean and free from excess moisture.
• Do not operate the UPS close to gas or electric heat sources.
• The system is not intended for outdoor use.
• The UPS operating environment should be maintained within the
parameters stated in this manual.
• Keep the UPS doors closed to ensure proper cooling airflow and to protect
personnel from dangerous voltages inside the unit.
• The UPS contains its own power source. Lethal voltages are present even
when the UPS is disconnected from utility power.
WARNING:
Only AUTHORIZED SERVICE PERSONNEL should perform service or
maintenance on the UPS or battery.
If service or routine UPS maintenance is required:
• Ensure all power is disconnected before performing installation or service.
• Ensure the area around the UPS system is clean and uncluttered.
• Battery cabinet maintenance or battery replacement should be performed
only by authorized service personnel.
• Observe all DANGER, CAUTION, and WARNING notices affixed to the
inside and outside of the equipment.
• Always conform to the more detailed safety precautions described in
“Important Safety Instructions” section of Chapter 15.
