Annex
13.4. Differing installation instructions for Thermo DC
11125620_
690 VDC supply line
The hook up must be made with at least a cable corresponding to the
heater connection cable (HV). The cable cross-section must be chosen
according to the power and installed cable length.
Use a dedicated power circuit for the heating system.
The appliance must have a fixed connection to the DC power supply.
The heating appliance must be connected to the potential equalization.
The connection must be carried out in accordance with the enclosed
hook-up diagram (see Figure 17).
