Sauna heaters and leakage current
Instructions Leakage current
For the installation of sauna heaters, please pay
attention to the DIN VDE 0100 part 703 !
This standard makes the following statement valid in your
newest expenditure, since February 2006, paragraph
703.412.05;
Quotation:
The additional must be planned for all electric circuits of
the Sauna by one or more fault current protection device
(RCDs) with a calculation difference stream not more
largely than 30 mA, excluded of it is Saunaheating.
The EN 60335-1 DIN VDE 0700 part 1 of January 2001
states the following in paragraph 13; quote:
The leakage current may not exceed the following values
during operation:
- for stationary heaters of protection class I 0,75 mA; or
0,75 mA each kW input of the appliance, depending on
the higher value, at a maximum value of 5 mA.
If the appliance is equipped with a protective device for
leakage current (ELCB), please pay attention to the fact
that no other electrical units will be protected by this ELCB.
Under current manufacturing methods, it is not yet
possible to produce tubular heating elements for sauna
heaters which do not attract moisture on each end from
the surrounding air.
Therefore, should the ELCB be triggered during start-up,
the electrical installation must be checked.
It is also possible that moisture from the surrounding air
has been concentrated in the magnesium-oxide filling in
the heating elements during transport or storage and is
now causing the ELCB to be triggered.
In this case, the oven must be heated up under supervision
of an expert, during which the PE conductor is not
connected. After about 10 minutes, when moisture has
evaporated from the heating elements , the oven must be
reconnected to the PE conductor!
If the sauna heater is not in use for a significant period of
time, we recommend running it every 6 weeks, so as to
avoid moisture concentrating in the heating elements.
Installation of the sauna heater and control unit may be
undertaken only by an authorized electrician. Without
documentation of such installation, a warranty is
fundamentally invalid.
