of 3 mm/0.12") and a fault current protection switch with 30 mA
trigger current (by client) in the mains supply line are mandatory.
The electrical isolator must be mounted in direct proximity of
the control unit (max. distance 1.0 m/39.37") and must be easily
accessible in a height between 0.6 m/23.62" and 1.9 m/74.8"
