ELECTRICAL
CONNECTIONS
Connect the sauna climate device to the
control device.
The electrical connection of the device
must be performed by a qualified per­
son in accordance with the applicable
standards and requirements.
The sauna climate device must be con-
nected in a half-stationary position to the
junction box on the wall of the sauna room.
The junction box must be splashproof and
its maximum height from the floor can be
up to 500 mm. The connection cable must
be a rubber insulated type H07RN-F cable
or equivalent.
ELECTRIC HEATER
INSULATION RESISTANCE
During the final inspection of the electrical
installation, leakage may be detected when
measuring the insulation resistance of the
sauna climate device, which has occurred
due to the insulation material of the heat-
ing elements absorbing moisture from the
air (storage, transport). After a few uses of
the sauna climate device, this moisture will
disappear.
NB! Do not connect the heater to the
mains via a residual­current device!
NB! Due to the potential danger of ther-
mal embrittlement, it is forbidden to use
a PVC-insulated cable as the connection
cable for the sauna climate device.
• The internal connections of the device
are made by means of screw terminals
according to Figure 2 and 3 and Table 1
in this manual.
• Protective earthing (PE) must be
connected to the connection termi-
nal of the device, with the cross-sec-
tional area of the cable being at least
2.5 mm2.
• The heater must be powered from
the 380 VAC (3-phase) or 230 VAC
(1-phase) 50/60 Hz supply circuit
through a control device protected
by an over-current fuse of the size
shown in Table 1 (see pages 10–11).
• If you want to connect the air circu-
lation fan of the device separately
from the heater control device,
the fan must be connected via a
residual- current device. In this case,
the protective earthing (PE) of the
fan supply input terminal of the
sauna climate device must not be
brought into contact with the pro-
tective earthing of the heater sup-
ply input terminal. In this case, use
earthed cables of at least 1.5 mm2 to
power the fan.
• The power cable must enter the
housing of the sauna climate device
so that the water does not flow along
