The ground connection of the two units depends on the electrical
protection class to be guaranteed
(see section 9 “Technical Data”
for more information).
This connection can be carried-
out using the mechanical part
supplied for ground connection
(
see Fig.14
).
Insert the support plate (M4x0.7
mm threaded holes) in one of
the two slots visible laterally on
the profile.
The two pins (M4x14) have to
be screwed on the external
support hole, leaving the central
hole free.
We suggest to screw the pins
using a Couple included
between 2.2 and 2.5 Nm.
The Couple guarantees that the
pin head passes through the
paint allowing the contact with
the metal housing.
Block the pins using the two M4
self-fixing nuts.
The nuts have to be tightened
using a hexagonal CH.7 wrench.
The nuts avoid the unscrewing
of the pins in presence of strong vibrations.
Insert the M4 ring and screw it on the central support hole.
