How to Install TI-S12048

• Power down the panel or enclosure and verify that the installation area is de-energized before mounting or wiring.
• Mount the TI-S12048 onto a standard DIN rail inside a protective enclosure or breaker panel. Ensure there is adequate clearance for ventilation and access to input/output terminals.
• Connect the AC input lines to the supply’s input terminals, observing correct polarity and securing with appropriate fasteners. Double-check that the input voltage matches the 100–240 VAC specification and that the supply is firmly seated on the DIN rail.
• Attach the 48 V DC output wiring to your load or PoE devices. Connect the positive output to the positive input of the load and the negative/return to the load’s ground/reference. Confirm that the total load does not exceed 120 W or the 2.5 A rating for sustained operation.
• Power the system on and verify operation. Use a multimeter to check that the DC output remains a stable 48 V under normal load conditions, and inspect for any unusual heating or audible noises. Ensure adequate ventilation to maintain safe operating temperatures within the enclosure.
