• Grounding can be done separately via a cable lug and the mounting hole if the module
is installed on a non-conductive subsurface
Ensure proper contacts and a sufficient cable cross-section.

8.1.9 Shielding Product

Use of shielded cables reduces electromagnetic interference and thus increases signal
quality. Measurement errors, data transmission errors and interference due to excessive
voltage can be prevented.
Connecting Cable Shield to Ground Potential
Integrated shielding is essential in order to meet the technical specifications regarding
measurement accuracy. Connect the cable shielding and ground potential at the inlet to
the cabinet or housing. This allows induced interference to dissipate and be kept away
from products in the cabinet or housing.
Improving Shielding Performance by Placing the Shield over a Large Area
Greater shielding performance is achieved by a low-impedance connection between
shield and ground. For this purpose, connect the shielding over as large a surface area
as possible. This is especially recommended for large-scale systems where equalizing
currents or high impulse-type currents (e.g., caused by atmospheric discharge) may oc-
cur
Keeping Data and Signal Lines Away from Sources of Interference
Lay data and signal lines separate from all high voltage cables and other sources of high
electromagnetic emission (e.g., frequency converters or drives).

8.2 Removal

8.2.1 Tools Required for Removal

For removal, you need an Allen key to unscrew the M4 cylinder head hex screws per
DIN 912/ISO 4762.

8.2.2 Before Removal

CAUTION
Device gets hot
During operation, high surface temperatures can arise on the metal housing and metal
connection sockets. If the product has been in operation, allow it to cool before touching
it, or use gloves.
Prepare for removal as follows:
1. If the product is contaminated, clean it before removal. It is especially important to
clean contaminated screw-clamp connections.
2. Before removal, loosen all screw connections on the connectors and disconnect the
cables.
