B.7.5 Installation in Environments with Explosive Dusts
Special attention must be paid to the following points:
• Before assembly, joint surfaces must be greased with Aeroshell grease.
• The cable glands must at a minimum possess a protection degree of IP66 or IP68
(15 m depth / 90 hours) according to IEC/EN 60529 standard.
• Periodically measure the quantity of dust deposited on the surface of the actuator
body. Clean the dust if it accumulates to more than 5mm high (relative to the
actuator body).
B.8 Maintenance
WARNING
Installation, conguration, commissioning, maintenance, and repairs must be performed
by approved and qualied personnel only.
B.8.1 Periodic Inspection
• Inspect the general condition of the XTE3000 and the possible optional additional
extension at regular intervals. The recommended frequency of inspection is once
every two years but this frequency could change depending on the installation and
working conditions. Any crack on the surface, broken windows, or loose bolts must
be reported for repair.
• Keep the external surfaces of the unit clean: if the unit is installed in a dusty
environment, the specication stated in IEC/EN 60079-14 is to be followed
(ensuring in particular that the dust layer does not exceed 5 mm).
• If the actuator is covered by an intumescent coating ("Kmass"), an electrostatic
charge risk is present; only anti-static cloth may be used when cleaning is required.
When performing maintenance, avoid rubbing actions against the actuator (or any
other friction-inducing action) that could electrostatically charge the unit.
• Check the condition of cable connections and mounting bolts; any loose
connection must be tightened.
B.8.2 Disassembly and Re-assembly
CAUTION
Using a fastener other than the approved type may result in damage to the actuator or
valve. Refer to Table 7.
CAUTION
Failure to use proper torque values can result in damage to the actuator and/or valve.
