INSTALLATION
4.1
Warning
• The NA1/3-C-T safety module
must be installed following the
standards in force in the country
of use, when the machine is not
powered and with no dangers for
the operator, on the machine’s
electrical board in a dry and
clean place (minimum protection
degree: IP54), fixed on the spe-
cial DIN rail.
• If the safety module is tampered,
it can not ensure the safety of
the operator any more and the
warranty is void.
• To avoid interference due to cou-
pling, run the limit switches con-
necting conductors separately
from the power conductors.
• Avoid the risk of short-circuits
between the terminals caused
by free cables, wires or material
that could come close to the
safety module.
• Avoid installation during storms.
