The MICO
cables can operate at temperatures above
200°C, without be susceptible to adverse effects;
other hand, cracks can occur on the additional coating in
LSF at temperatures below -20°C without
functionality of the cable. This is why you should not run the
installation of coated cable with extra cover in LSF at
temperatures below -20°C.

TERMINATION EXECUTION
Cut the end of the cable by a small saw; place the stripper on
the cable and tighten it: the blade must be in contact with the
copper outer sheath and the V shaped clamp must be
tightened on the cable by its screw, so to let the tool spin round
with the cable without stopping it.

Start rotating the tool pushing it towards the inner part of the
cable; avoid the rolling up of the copper shaving on the
conductors, fixing it on the suitable hook.
When you have stripped enough copper sheath, you can insert
the pliers to cause the drop of the copper shaving
Clean the conductors and insert the gland components (body,
double cone and press cone).
Only for use in explosion-proof applications, glands

potentially explosive areas (zone 1 and zone 21) use only RAD

In case that the fitting/housing coupling is subjected to
vibrations it is necessary, in order not to cause breakage of the
cable, to make a compensation bend in the vicinity of the
housing. In case of ATEX applications the fitting/housing
coupling shall guarantee at least 5 threads and the minimum
housing thickness must be greater than or equal to 10 mm,
moreover, the lock nut (see last figure) is not present in these
coupling.
The seal is guaranteed by the full tightening of the metal
double cone through the cone press and is ent
care of the installer.

UNINSTALLING AND DISPOSAL
Before proceeding to final dismantling it is necessary to
separate the various parts that could cause pollution, make a
selection of materials in order to facilitate recycling, to earmark
separate disposal.
