Electrical characteristics of the board

Stresses above the limits shown in Table 2 may cause permanent damage to the devices

present inside the board. These are stress ratings only and functional operation of the

device under these conditions is not implied. Exposure to maximum rating conditions for

extended periods may affect device reliability.

A 15-V bias current measurement may be useful to check the working status of the board. If

the measured value is considerably higher than the typical value, some damage has

occurred to the board. Supply the control board using a 15-V power supply connected to J10

respecting the polarity.

Warning:

To avoid damaging the board when feeding the +15-V voltage

supply through the auxiliary connector (J10), remove jumper

J8 and supply the +15 V before connecting the mains.
