• Cross section of the electrical cable shall be increased, if the cable and
water heater are located on a thermally insulated or heating wall.
• Wires of the electrical cable in the terminal block of the water heater and
power switchboard shall be secured, since a loose connection may result

with hot surfaces.
• Do not connect the grounding loop of the water heater to water/gas
supply lines, etc.
• Make sure that electrical wiring is properly connected (including connection
