How to install APC WW 20KVA Isolation Transformer

• Prepare the rack space: Ensure you have a clean, ventilated 19-inch rack with adequate clearance for cooling and access to rear cabling.
• Mount the transformer: Use the included rack mounting brackets to secure the 4U unit into the rack. Align mounting holes and fasten securely to prevent vibration and movement during operation.
• Connect the input power: Follow local electrical codes to connect the primary (input) side to the mains supply using the hardwire panel. Verify that the input voltage matches the transformer’s 208/230/240V range and observe proper grounding.
• Route and connect the load: Connect the secondary (output) side to the equipment rack or individual devices that require isolated, conditioned power. Label connections clearly and keep power cables organized to maintain airflow and reduce interference.
• Safety check and power up: Confirm all connections are secure, verify grounding continuity, and inspect for any signs of damage or loose hardware. Power up gradually, monitor voltage stability, and confirm the absence of alarming noise or overheating during initial operation.
