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 certied
the extension(s). The method of sealing and cable glands used must be approved and

NOTICE
To prevent water inltration through the line cable conduits, ensure that the cable glands used
possess the minimum degree of protection required by the plant and are specied on the
actuator label. If a rigid conduit makes a connection to the plant, it is recommended to place a
exible pipe connection between the conduit and the conduit entry of the additional extension.
To guarantee that the weather-proof and explosion-proof characteristics are maintained,
screw the cable gland or the external ATEX-certied apparatus tightly (at least 5 turns of
engagement) and coat them with a thread sealant.
NOTICE
All accessories (including cable glands) must comply with approved specications for the
site requirements and be certied according to the standard directive. When selecting
cables and cable glands, the maximum temperature of the cable (indicated on the product
label of the base XTE3000) must be considered.
