Power supply checks

Step-by-step instructions

Estimated execution time: 0,5 hours

§  Temporary connect a power lead to the AC terminal block:

The voltage over both 
electrolytic capacitors (e-caps) should be around 25V DC. While measuring this DC voltage also check the polarity of the capacitors. Immediately power off the device if there is a mispolarisation.

§  Assemble the backplane and power supply. Power on and check if the led lights up. Immediately power off the device if the led stays dark:

§  Before proceeding to one of the following checks, double check the different DC voltages on the corresponding pins on the right side of the PCB:

§  Pinout:

Important warning

A limited number of components will be connected to the mains voltage and can be dangerous if used incorrectly. It cannot be stressed enough to disconnect equipment before and servicing. Depending on local regulations, use approved connectors, wiring and insulation for the mains voltage connection. If you are unsure do not continu and contact a professional for assistance.
