VEGASWING 71A and 75A 9
Mounting
Transport
Do not hold VEGASWING on the tuning fork.
The tuning fork can be damaged.
Polished version (VEGASWING 75A)
Treat instruments with polished tuning fork
(VEGASWING 75A) very carefully and do not
touch the polished surface.
Unpack VEGASWING 75A directly before
mounting. Insert VEGASWING carefully into
the provided opening and avoid contact with
vessel parts.
Cable entries
When mounting outside, on cooled vessels or
in humid areas in which e.g. cleaning is done
with steam or high pressure, the seal of the
cable entry is especially important. Use cable
with sufficient wire cross-section and tighten
the cable entry. For cables with too small wire
cross-section, a suitable reduction piece
must be used to ensure tightness of the
cable entry.
Two seal rings are attached to the instrument
to ensure tightness also of cables with
smaller diameter. Use the smallest possible
seal ring.
To avoid humidity ingress, the cable entry
should point downwards (see fig. 2.4).

Proceed as follows: Loosen the plug by un-
screwing the knurled ring. Loosen the con-
nection screw and remove the socket insert
out of the angular housing of the plug (see
also fig. 3.1 under "3.1 Connection instruc-
tions").
You can turn the angle housing of the plug in
60° steps (see fig. 2.5).
With vertically mounted VEGASWING, loop
the connection cable to the instrument hous-
ing downwards so that rain and condensation
water can drain off.
Welded socket G 1 A
VEGASWING’s thread start is defined. This
means that each VEGASWING is in the same
position after screwing in. Therefore remove
the supplied seal from the thread of VEGAS-
WING. This seal is not required when using a
welded socket (G 1 A). Screw VEGASWING
into the welded socket.
You can determine the subsequent position
of VEGASWING before welding (see also fig.
2.3). Mark the appropriate position of the
welded socket. Before welding, unscrew
VEGASWING and remove the rubber ring
from the socket.
An optional welded socket (G 1 A) is avail-
able which is already provided with a notch.
Weld this socket with a marking facing up-
wards (see fig. 2.6).
