Notes :
• Sealing devices must be used and shall be fitted directly at the enclosure wall when using conduit.
• Cable glands shall be suitable for the environment and shall be certified as flameproof if used in Zone 1
application.
• Cable glands and conduit to be installed for minimum 6 full threads and the thread length must be 8mm
minimal.
• The temperature of the cable entry is maximum 100
℃
. A heat resistance cable is recommended.
• Ex db and/or Ex tb certified cable glands suitable for 100
℃
must be used.
• Minimal requirements concerning the material and the allowance of LCU fasteners:
o Fasteners with yield strength ≥ 210MPa (stainless steel)
o Bolts type: M5x0.8, M6x1, M8x1.25, M10x1.5, M12x1.75 (Tolerance Fit 6g).
• Cable connection: Refers to the Appendix I - (Wiring Diagram)
• For cable entries or conduit entries that are not used, user or installer shall close them with certified blanking
elements (stopping plugs) in order to maintain flameproof or dust ignition proof properties of the enclosure.
• Always ground the enclosure in accordance with local electric codes. The most effective enclosure grounding
method is a direct connection to earth ground with minimal impedance. Methods for grounding the enclosure
include:
o Internal ground connection: The internal ground is located in the terminal block #1. Refer to the
enclosed wiring diagram.
o External ground connection: The ground lug is located on the centre of cable entries. For more
information, refer to the Appendix II – (Grounding).
• Stainless steel name plates for the flame proof and dust ignition proof versions shall be permanently attached
by rivets.
2.2 Initial Inspection
Upon on the receipt of the actuator, the user should inspect the condition of the product and ensure
that the product specification stated on the name plate matches with the order sheet.
• Remove the packing wrap or wooden box carefully. Inspect the product for any physical
damage that may have occurred during shipment.
• Check the product specification of the received product. If a wrong product has been
supplied, please immediately report this to the distributing company.
2.3 Storage
Actuators must be stored in a clean, cool and dry area. The unit should be stored with the cover
installed and the conduit openings sealed. Storage must be off the floor, covered with a sealed
