Installation
• Cables with double shielding: in this
case, one shielding is connected to the
analyzer housing, the other shielding
to the external device. This is advanta-
geous when both units are supplied from
different grids (e.g. when installed in dif-
ferent buildings). Other precautions for
connections between buildings are the
use of ber optic cable.
This method is more expensive, but
gives the best protection against external
interference and against interference cur-
rents
.

2.7 Installation - Notes on wiring
X-STREAM XEGP with XSTA or XSTD ter-
minal adapters
In order to avoid measured values being
inuenced by external interference signals
when terminal adapters are in use, the signal
cable shieldings must be connected to the
analyzer housing by means of shield connec-
tor terminals:
The signal cable shielding is uncovered to a
length of 20 cm (8 in), the contact part of the
shield connector terminal pulled up, the cable
fed through as illustrated in Fig 2-17, and the
contact part brought down 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:
