RECOMMENDED TOOLS
PREPARATION OF WALL MOUNTING
Drill two Ø 8 mm holes (see drilling diagram) and insert the
appropriate dowels into the holes. Use screws with a max.
diameter of 6 mm to fasten the enclosure.
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.
2Insert a flat-tip
screwdriver between the
locking arm and the rear
bar and push the locking
arm forward a few mil-
limetres by turning the
screwdriver
3Turn the headless
screw back with the Al-
len wrench (size 2) until
it is protruding slightly
out of the locking arm
1Tighten the head-
less screw with an Allen
wrench (size 2) until the
locking arm is flush with
the side bars

6Fasten the junction box on the wall or on the mounting
bracket.
FASTEN THE JUNCTION BOX
CONNECT THE PT 100
ATTENTION
• Please observe the respective installation instructions for
the sensors to be connected.
• Make sure that all terminals and cable glands are tighte-
ned according to the instructions.

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.

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.
MARKING (made by customer)
NOTE
Customer-side labeling with an identification plate is pos-
sible.
