How to install Powerware Maintenance Bypass Panel

• Plan and assess: Begin with a site survey to confirm electrical room space, ventilation, and accessibility. Verify that the UPS and load requirements align with the panel’s 15 kW, 220 V AC specifications. Confirm that all safety protocols, permit requirements, and lockout/tagout procedures are in place before starting installation.
• Power down and isolate: De-energize the UPS and isolate it from the distribution network per your facility’s safety policy. Ensure the critical load is stabilized and that appropriate grounds are established. This step minimizes risk during installation and testing of the bypass path.
• Prepare mounting area: Ensure a clean, dry, and well-ventilated space. Mount the panel on a solid, accessible surface or rack as specified by the installation plan. Verify clearances for door access, serviceability, and cable routing. Route input, bypass, and load conductors with proper strain relief and separation from other live components.
• Connect input and bypass paths: Attach the input power conductors to the panel’s input terminals and connect the bypass path to the corresponding bypass terminals. Use appropriately rated cables and hardware, tighten connections to the recommended torque specifications, and verify that all termination points are secure and properly labeled to prevent confusion during future maintenance.
• Connect the critical load: Wire the critical load conductors to the panel’s load terminals in accordance with the electrical design and local codes. Confirm that the load path is isolated from the UPS path when the bypass is engaged and that the wiring configuration supports safe, predictable transfer between UPS and bypass.
• Install interlocks and safety features: Ensure that mechanical interlocks and protective covers are properly engaged. Check that the bypass cannot be activated while the UPS is online and that interlocking prevents inadvertent contact with live components during maintenance.
• Commissioning and testing: After wiring is complete, restore power in a controlled sequence and perform functional tests per the installation plan. Verify that the bypass path engages correctly, that load transfer is smooth, and that alarms, indicators, and interlocks operate as intended. Schedule and document a formal acceptance test with facility personnel and, if applicable, the UPS vendor’s service technician.
• Documentation and labeling: Update electrical drawings, cabinet labeling, and maintenance records to reflect the new bypass configuration. Include serial numbers, commissioning dates, test results, and a contact point for future support. Proper documentation ensures quick future service and compliance with audits.
• Ongoing maintenance: Establish a routine inspection schedule for the panel’s interlocks, wiring, and terminations. Check for signs of wear, corrosion, or heat discoloration and address issues promptly to maintain reliability and safety over the panel’s service life.
