1. Technical Data
2. Mounting
The panel heater is fitted vertically, i.e. with
the connection terminal or fan facing down-
wards. To permit the required convection, a
gap of at least 100 mm must be left above
and below the heater. In the case of heaters
with fans, a safety clearance of min. 300 mm
to any component installed above must be
observed (thermal safety clearance to adja-
cent components at least 35 mm). If these
clearances are observed, the ambient tem-
perature does not rise above 65°C.
2.1 Screw fastening onto the mounting plate
(Fig. 2.4).
2.2 Snap-type fastening onto a 35 mm
support rail DIN EN 50 022
(Fig. 2.3/Fig. 2.5).
It is furthermore to be ensured that the heater
and connection cables are mounted firmly
and securely.
Electric cables must not touch the body of the
heater fan and must not be routed directly
past the hot air outlet. The heater must
not be mounted in the vicinity of flammable
materials.
