• Cables with double shielding are used: in
this case, one shielding is connected to
the analyzer housing, the other shielding
to the external device. This is advan-
tageous when both units are supplied
from different grids (e.g. when installed
in different buildings).
This method is more expensive, but gi-
ves the best protection against external
interference and against interference
currents
.

2.7 Installation - Notes on Wiring
X-STREAM X2GP with XSTA or XSTD ter-
minal adapters
In order to avoid measured values being inu-
enced by external interference signals when
terminal adapters are in use, the signal cable
shieldings must be connected to the analy-
zer housing by means of shield connector
terminals:
• uncover the signal cable shielding to a
length of 20 cm (8 in),
• pull up the contact part of the shield con-
nector terminal,
• feed through the cable as illustrated in
Fig 2-17,
• bring down the contact part onto the
shielding.
This results in a secure contact with the cable
shielding and improves the unit’s interference
resistance.
The individual wires are then connected as
described in seciton 2.6.

The shield connector must be properly or-
dered to t the cable diameter, and can be
retrotted:
