Safety Notes for Commissioning
The commissioning must be done only by adequately qualified personnel and with power sup-
ply switched off.
On initial operation of the monitored machine the operator must ensure proper function of the

speed condition.
If voter inputs are used the correct trip release due to external trip condition must be verified.
The parameter settings must be documented and protected against unauthorized changes.
