1. Technical speciÞcations

2. Mounting

The panel heater is fitted vertically, i.e. with
the connection terminal or fan facing down­wards. To permit the required convection, a
minimum clearance to the adjacent compo­nents must be observed. A safety clearance
of at least 300 mm must be left above the
heater in the case of heaters with fans, and
100 mm for heaters without fans. (For both
a thermal safety clearance to the sides of
60 mm and 100 mm at the bottom is
required).
If these clearances are observed, the ambi­ent temperature does not rise above 65 ˚C.

2.1 Snap-type fastening onto a 35 mm
support rail DIN EN 50 022 (Fig. 1.1).

2.2 Screw fastening onto the mounting plate
(Fig. 1.2).

It should 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.
