Cable Connection

When optional extensions for additional entries or additional electronic cards are
connected to external cables or conduits, the sealing of these entries must be carried
out in accordance with the national standards or regulatory authorities that certified
the extension(s). The method of sealing and cable glands used must be approved and
separately certified for use in hazardous areas.
Two earth connection points - one internal and one external - are located on the XTE3000
base model (see Figure E-7) for connection to ground cables.
NOTICE
To prevent water infiltration through the line cable conduits, ensure that the cable glands used
possess the minimum degree of protection required by the plant and are specified on the
actuator label. If a rigid conduit makes a connection to the plant, it is recommended to place a
flexible pipe connection between the conduit and the conduit entry of the additional extension.
