INSTALLATION
ATTENTION
• The following steps should only be carried out by
persons trained in handling electrical equipment.
• Strict compliance with the relevant standards and safety
regulations is a requirement for the safety of persons,
plants and equipment.
• The persons entrusted with the planning, installation
and maintenance bear a special responsibility and must
therefore be thoroughly familiar with the applicable re-
gulations.
• These instructions are intended for this group of people
and contain all the important information required for
the safe handling (Maintenance & Inspection).
SAFETY INSTRUCTIONS RECOMMENDED TOOLS
ASSEMBLY INSTRUCTIONS
ATTENTION
• When selecting the mounting location, take into ac-
count the degree of mechanical danger to the junction
box and the cable entries as well as the permissible am-
bient temperature.
• Ensure that the surface on which the junction box is
mounted is capable of bearing loads.
• Cables inserted into the junction box must be laid firmly
and secured against being pulled out of the cable entry
(e.g. by a cable clamp).
• Unused clamping points must be tightened.
• Before inserting blind plugs, reducers or conduit entries
into free threaded boreholes, make sure that the threa-
ded borehole is clean and undamaged and that the re-
spective threads fit together.
• After connection, all openings must be closed tightly
(cover, threaded boreholes, cable entries). Use suitable
open-end, ring or socket spanners to tighten the cable
entries.
• The lid of the junction box is designed to mount a iden-
tification plate provided by the customer. Use screws Ø
2.2 x 6 mm for fastening.
PLACEMENT OF ELAK-RS1 Do not fasten heating
cable and sensor line at
the planned measurement
point approx. 500 mm.
2 Prepare the end of the sensor line with a strong wire and
by using adhesive tape to lead a sensor line into the mounting
base.
3 Lead a sensor line
into the opening
provided and pull it
about 200 mm into the
mounting base.

5 Cut off the end of the
heating cable at an angle of
about 45°.
7 Guide the heating cable
about 200 mm through the
mounting stand.
6 Guide the heating cable
into the mounting stand.
8 Fasten the mounting stand
onto the pipe with a strap. Do
not feed tightening strap above
heating cable or sensor cable!
9 Mount the heating cable
connection (not included
with delivery).

1Visual inspection of housing and cover to ensure they are
not damaged. Cover can only be inserted in one position (lok-
king arms / twist protection recesses have different width).
Move the cover to the appropriate position.
2Fasten the cover with the narrower locking arm (without a
headless screw), close the cover and…
3Use the pliers to lock the cover
CLOSE THE JUNCTION BOX CHECK AFTER INSTALLATION
ATTENTION
After completing the installation, the following steps must
be taken:
• Visual inspection of the junction boxes for possible me-
chanical damage.
• Damaged junction boxes must not be put into operation
and must be replaced.
• Check the cover of the plenum box and its attachments
(cable entries) for tight fit.
• All threaded openings must be fitted with cable entries
or blind plugs, which must be firmly tightened and tight.
OPERATION & MAINTENANCE
DANGER
• The junction boxes may only be opened (this also in-
cludes loosening cable entries!) in a de-energised state.
disconnected from the power supply.
• Damaged junction boxes must not be put into opera-
tion.
ATTENTION
When operating the junction boxes, the permissible ambi-
ent temperature must be observed.
• The locally applicable safety regulations must be obser-
ved.
• The permissible operating conditions according to
„Technical data“ or labelling (voltage, current, operating
temperature, maximum ambient temperature, IP protec-
tion class) must be observed.
• It is recommended to visually check the integrity and
tight fit of the cable gland and the connected cable at
suitable intervals depending on the installation location
and application.
• If necessary, the cable entries must be retightened, da-
maged junction boxes or cable entries must be replaced
by qualified personnel.
• If repair work is to be carried out on heated system parts,
the junction boxes must be protected against damage.
• After completion of the repair work, the plenum box
must be checked again.
