1.
The instrument can be inserted into a panel cut-out
of any size between the minimum and maximum
dimensions illustrated, provided the cut-out is
positioned centrally relative to the fixing holes. If the
panel cut-out is larger than the maximum, a locally
manufactured adaptor plate will be required.

If panel-mounting to NEMA 4X hosedown standard
is required, a continuous bead of suitable silicon
sealant
must
be applied beween the case flange
and the panel.
