sometimes moving or rotating parts as well as hot surfaces during operation.

tions as well as on any connected cables and terminals. This can also be the case if
the motor is at standstill.

controlled machine, first disconnect the product from the supply system and then start
troubleshooting.
Risk of burns: The surface temperature of the product can exceed 60 °C during opera-
