How to install Vertiv Psi5 5kVA UPS

• Choose a location with solid, level support and adequate airflow. Ensure there is enough clearance for maintenance access and for cooling airflow around the unit.
• Mount the Psi5 in a standard 19-inch rack if rack-mountable configuration is selected, or prepare a stable floor support if using the tower setup. Use the appropriate mounting hardware supplied by Vertiv to secure the unit safely.
• Connect the input power to a dedicated, properly rated 208 VAC supply. Follow local electrical codes and use appropriate circuit protection (circuit breakers) to guard against faults.
• Connect critical loads to the UPS output outlets or to a clean-power distribution solution that is compatible with the Psi5’s outlets. Do not overload the UPS beyond its 4500 W rating; plan a load profile that leaves headroom for startup surges.
• Power on the unit and perform the built-in self-test using the LCD interface or the supported software tool. Configure basic settings such as input/output voltage references, alarm thresholds, and remote-management options. If you plan to extend runtime, install external battery cabinets and configure runtime expansion in the management interface.
