how to install Tripp Lite by Eaton 7-Amp DC Power Supply

• Place the power supply on a stable, vibration-free surface near your equipment. Ensure there is adequate clearance for air flow and access to input and output connections.
• Verify that the mains outlet is a standard 120 V AC supply with appropriate circuit protection (breaker or fuse) before connecting the unit.
• Connect the power cord to the AC input on the power supply, then plug the other end into the wall outlet. Do not power on the device until all connections are secure.
• Attach the DC output leads to your equipment using the correct polarity (positive to red/plus, negative to black/minus). Use appropriate gauge wiring for the current you expect to draw and avoid daisy-chaining multiple devices beyond the supply’s rating.
• Turn on the power supply and monitor the output with a multimeter or the connected equipment’s built-in meters. Confirm a stable 13.8 V DC within the ±0.5 V tolerance under nominal load, and verify that the load operation remains within the 7 A limit.
