Safety function checks in the maintenance routine

It is a good practice to check the operation of the optional safety functions at
appropriate intervals.
If the drive is equipped with optional safety functions +Q950, +Q951, +Q952, +Q954,
+Q963, +Q964 or Q968, include the safety function tests described in Safety options
instructions for ACS800 drives (3AUA0000026238 [English]) to the routine
maintenance program of the machinery that the drive runs.
If you replace a circuit board or wire set inside the drive module, re-test the safety
function.
If you detect any failure in safety functions, contact your local ABB representative.
