Cable Connections and Routing
The cables are to be routed through the bottom of the UPS cabinet.
Note: An additional optional cabinet is required if cable routing is required for top cable connections.
The cables may be routed as follows:
- In a trench running under the cabinets
- Under a false floor
- On the floor in the free space under the cabinets.
Note: Run cables side by side under the cabinets to avoid blocking the flow of air for ventilation.
The cables should be connected as follows:
- To the normal AC input terminals
- To the bypass AC input terminals
- Between the battery and UPS cabinets (power and control cables)
- Between the bypass AC-source transformer in an auxiliary cabinet and the UPS cabinet
Only the wires for the inter-cabinet control connections between parallel connected UPS units are supplied. The other power cables for connections between the cabinets are not supplied.

Caution should be taken to ensure sufficient isolation of power, control, and communication cables. Running the cables together could cause unintentional contact with live power cables resulting in injury or death. Run the communication cables separately from the power cables. Reinforce the insulation of the control and communication cables if any risk of contact with the power cables exists. |
