Important Information:
(1)
Only screws with cylindrical heads are suitable for mounting the tag. We do not advise using counter-
sunk screws. If for some reason this should be necessary, then only together with a suitable counter-
sunk cushioning disc

.
(2)
Secure the screws so they cannot work themselves loose i.e. by using self-locking nuts or spring washers
or Nordlock washers

.
(3)
If the tag is mounted out-of-doors or in a damp environment, all mounting parts need to be made of
stainless steel or other non-rusting material.
(4)
A temperature of at least +10°C (+50°F) must be maintained during mounting to prevent the casing
from cracking.
(5)
Depending on the type and strength category of the M5 screw used, the maximum tightening torque
must be between 2 and 10 Nm. If the torque is any greater, the screw may overtighten, or the casing
might break.
(6)
Metal surfaces in direct proximity to the tag can reduce the tag’s range of function. Tags should therefore
not be mounted in metal recesses or corners.
(7)
After mounting, the tag’s function should be tested, i.e. with a handheld.
