EN 60204-1 (IEC 60204-1) with the use of protection devices that ensure automatic cut-
off of the supply in case of isolation fault in the TN or TT systems or, for IT systems, the
use of isolation controllers or differential current protection devices to activate automatic
power disconnection (an isolation controller must be provided for indicating a possible
first earth fault of a live part, unless a protection device is supplied for switching off the
power in case of a such a fault. This device must activate an acoustic and/or visual
signal which must continue for the entire duration of the fault). For example: in a TT
system, a residual current device with cut-in current (e.g. 30 mA) coordinated with the
earthing system of the building where the machine is located must be installed ahead of
the supply.
• On all rack type dishwasher, make sure to install an emergency switch at the infeed and
