HANDLING
The
user
space
cover
enables
access
to
the
user
interfaces

parts.
The
cover
is
attached
by
2
M6
bolts
that
can
be

One
of
the
bolts
can
be
only
partially
loosened,
which
ensures
attachment
to
the
box
during
manipulation
with
the
cover.
Retightening
of
this
bolt
in
open
position
enables
locking
of
the
lid
in
any
position.
Since
the
user
buses
are
located
in
the
inside
hermetically
enclosed
space
of
the
box,
the
lid
is
provided
with
a
gasket.
To
protect
the
gasket
from
damage,
please
rigorously
keep
