How to install Vertiv Liebert TDU

• Before you begin, ensure the power is completely shut off and that you comply with all local electrical codes and safety practices. Review any installation manuals or labeling on the unit for wiring references.
• Choose a stable, well-ventilated location with enough clearance for cooling, access to connections, and ease of maintenance. The Liebert TDU can be placed near the equipment it serves, either on the floor or in a dedicated cabinet area, as appropriate.
• Plan input and output routing. Identify your 208 VAC and/or 240 VAC input supply and the 120 VAC loads that will be fed by the TDU. Ensure that wiring paths minimize exposure to heat sources and physical damage while allowing for safe serviceability.
• Connect the input side of the Liebert TDU to the appropriate power source according to the unit’s labeling and wiring diagram. Use proper gauge wiring and secure connections to prevent loose contacts. Grounding should be established in accordance with local electrical codes.
• Connect your 120 VAC devices to the TDU’s output connections, taking care to distribute the load evenly and avoid exceeding the rated capacity. Double‑check polarity and grounding for all connected equipment.
• Power on the system and verify output. Use a voltmeter to confirm that the output is delivering a stable 120 VAC under normal load conditions. Observe the unit for any unusual warmth, noise, or smells, and verify that all devices operate as expected.
• Document installation details and schedule routine inspections. Maintain clear labeling of input and output circuits, and keep spare parts or service contacts readily available to minimize downtime in case of maintenance or component replacement.
