WIRING
A bipolar switch should be fitted between the appliance and the grid. The switch contacts should have a
minimum opening of 3 mm, with 5 A max. fuses. Connect the appliance to an electric line of 230 V - 50 Hz

Make sure that the unit is connected to an efficient earthing system.
Joannes declines responsibility for damage or physical injury due to failure to connect the unit to an
efficient earthing system.
