• the electrical supply of the heater must come from a protection and switching device (not supplied)
complying with the standards and regulations in force in the country where it is installed (in France,
refer to standard NF C 15100). The RE/U from 3 to 9 kW may be supplied by single-phase
(230V/1N/50Hz) see figure 1, or in three-phase (400V/3N/50Hz), see figure 2. The 21 and 24 kW
RE/U
must
be supplied with three-phase current (400V/3N/50Hz).
• supply cable section: this section is recommended for cables of a maximum length of 20 metres,
with a calculation base of 5A/mm². It must be checked and adapted if necessary, depending on
installation conditions:
