HL-20KN
Cert.No. : 1454-255
IP68
Applied Standard : KS C IEC 60529(2002) & IEC 60529(2001)
HL-25KN
Cert.No. : 1471-272
IP68
Applied Standard : KS C IEC 60529(2002) & IEC 60529(2001)
NOTE :
Sealing devices must be used and shall be fitted directly at 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 minimum 6 full threads and the length of thread is minimum 8mm.
Temperature of cable entry is maximum 100
℃
. Heat resistance wire is recommended when you install.
Cable connection : Refers to the Appendix
Ⅱ
(Wiring Diagram)
For cable entries or conduit entries that are not used, user or installer shall close by certified blanking
elements(stopping plugs) so that the flameproof properties of the enclosure are maintained.
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:
Internal ground connection : The internal ground is located in the terminal block #1. Refers to the enclosed
wiring diagram.
External ground connection : The ground lug is located on the centre of cable
entries.

Initial inspection
When the user receipt the actuator, inspect the condition of the product and ensure the name plate comparing with order
sheet.
Remove packing wrap or wooden box carefully. Inspect the product for any physical damage that may have
occurred during shipment.
Check the product specification with product ordered. If a wrong product have been shipped, immediately
report to our coordinator.
2.3
Storage
Actuators must be stored in a clean, cool and dry area. The unit shall be stored with the cover installed and the conduit
openings sealed. Storage must be off the floor, covered with a sealed dust protector.
When actuators be stored outdoor, they must be stored off the ground, high enough to prevent being immersed in water
or buried in snow.
