1. Technical speciÞcations
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
minimum clearance to the adjacent compo-
nents 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 ambi-
ent 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 con-
nection cables are mounted firmly and secu-
rely. 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 vici-
nity of flammable materials.

3. Mains connection
The heater must be connected to a power
supply of the voltage stated on the rating
plate via the quick-connect terminals. The
unit must be connected to the mains via an
isolating device which ensures at least 3 mm
contact opening when switched off.
Electrical connections must be made using
solid wire (max. 2.5 mm
2
) or stranded wire
with wire end ferrules.
Due to the specific characteristics of the PTC
heater element, the momentary switch-on cur-
rent may be up to 6 A. A slow-blowing fuse
(gL) is therefore imperative. IEC 6100-4-5
requires that the customer provides safety
devices for impulse voltages of more than
1000 V. The double connection terminal per-
mits the cascading of several heaters and
thus simplifies wiring. A separate thermostat
(SK 3110.000) or a digital thermostat
(SK 3114.200) must be used to control the
enclosure temperature.
The humidity of the air in the enclosure can
be controlled by incorporating a hygrostat
(SK 3118.000).
3.1 Proper usage
Rittal enclosure heaters were developed and
designed in accordance with the state of the
art and the recognised rules governing tech-
nical safety. Nevertheless, if used improperly,
they may pose a threat to life and limb or
cause damage to property. The heater is only
designed to heat components and to be
installed inside housings and enclosures.
The manufacturer will not be liable for any
damages caused as a result of improper use,
or for incorrect assembly, installation or use.
All risk is borne solely by the user.
4. Safety notes
● When carrying out the electrical installation,
it is important to observe all valid national
and regional regulations as well as the
provisions of the responsible power supply
company.
● Electrical installation must only be carried
out by a qualified electrician who is
responsible for compliance with the existing
standards and regulations.
● Use only original spare parts!
● The heater must not be touched while
switched on : Risk of burns from hot
surfaces! The heater must be allowed to
cool for approx. 15 minutes after switching
off.
