Questions about this item

How do I connect the 4-pin plug to my TM-C3520 without bending the pins?

Align the keyed notch on the 4-pin connector with the socket on the TM-C3520, push straight in until it clicks, and avoid angling the plug which bends the delicate pins.

When should I replace the M248A adapter if the output drops below 42 V or 1.38 A?

Replace the unit when a multimeter shows less than 42 V or 1.38 A under load, or if the brick becomes excessively hot during normal 58 W operation.
