How to install APC 32A Maintenance Bypass Panel

• Plan the installation in a dedicated, well-ventilated rack space with clear access to electrical outlets, UPS units, and distribution panels. Verify that the rack size and mounting location meet the panel’s 19-inch mounting requirements and that there is no interference with other equipment or cables.
• Power down the UPS and the connected critical load according to your facility’s safety procedures. Disconnect power sources as appropriate and ensure that all personnel follow established lockout/tagout protocols before mounting or wiring the bypass panel.
• Mount the APC 32A Maintenance Bypass Panel into the rack, securing it firmly to the rack rails. Ensure the panel is level and accessible for wiring, testing, and future maintenance. Route cables cleanly to minimize clutter and reduce airflow disruption.
• Connect the bypass panel’s input and output terminals to the UPS and to the critical load as specified by your UPS model and load requirements. Use the appropriate gauge wiring and ensure all connections are tight and properly labeled for future maintenance. Confirm there are no loose connections or signs of damage.
• Install the three bypass breakers and configure them according to your maintenance procedures. Label each breaker to clearly indicate its function and the circuit it serves. Check for proper clearance around the breakers and ensure that activation/deactivation can be performed safely without obstruction.
• Restore power and perform a controlled transfer test. Switch the system to bypass mode to verify that the UPS is isolated from the critical load and that the bypass path carries the intended current without interruption. Return to normal operation and confirm that all equipment resumes normal power supply smoothly.
• Document the installation, including wiring diagrams, breaker settings, and testing results. Maintain an up-to-date maintenance log so future technicians can quickly understand the bypass configuration and the recommended maintenance workflow.
