UPS Power Supply Connection Diagram
The online double-conversion UPS acts as the core of the system. It continuously converts incoming AC power to DC. Then it converts the DC back to clean, regulated AC power. This design fully isolates the load from input power disturbances such as voltage fluctuations, frequency variations, and electrical noise.
An external battery bank or battery cabinet is connected to the UPS to provide uninterrupted backup power during mains failure. The UPS automatically switches to battery mode without interruption, ensuring continuous operation of connected equipment.
The conditioned and regulated output power from the UPS is delivered to various critical loads. This includes servers, data centers, security systems, networking equipment, and industrial devices. This ensures maximum protection and reliability.

How to Install
Safety Precautions
-
Installation must be performed by qualified electrical personnel only.
-
Before installation, ensure the input power supply is completely disconnected.
-
Use proper personal protective equipment (PPE) during installation.
-
Ensure the UPS is properly grounded to prevent electric shock.
-
Do not operate the UPS if there is visible damage.
Positioning the UPS
-
Place the UPS on a flat, stable surface or mount it according to the cabinet design.
-
Ensure the unit is level and securely positioned to prevent movement.
Electrical Wiring (Three Phase)
Important: Follow the wiring diagram provided on the UPS or in the manual.
Input Power Connection
