Residual-current circuit-breaker with overcurrent protection protects the user against touch voltage and leakance. It
is absolutely necessary to test it as described in “Before each start-up” chapter by pressing the Test button in normal
operation mode. When the Test button is pressed, this safety device should be activated to disconnect power. In
various machines’ residual-current circuit-breakers, the Test button is located as below.
One of conditions of proper protection against electric shock is that the machine’s electrical installations must be pe-
riodically inspected by entities authorised thereto to. Pay special attention while you repair or adjust your machine,
as most of its elements are very hot, and you can get serious burns if you touch them directly. Since this is a pressure
machine, be careful when you operate or adjust it. In the event its pressure system is unsealed when in operation,
you can undergo severe burns from high-temperature steam. Persons who perform maintenance / adjustments at
this machine should hold relative permits and logbooks that allow them to carry out maintenance/ adjustments on
thermal pressure equipment (Group G2 energy licence) and electrical equipment (Group G1 energy licence).
