⑤ CSA: for HQ-008 ~ HQ-300, 249581 (except HQ-060) Ordinary location
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 min-
imum 8mm.
Temperature of cable entry is maximum 90℃. Heat resistance wire is recommended when you in-
stall.
Ex d certified cable glands suitable for 90℃ must be used.
Users should confirm all information about dimensions of flamepath with the manufacturer
All information about the material and the allowance of LCU fasteners. [However LCU is not apply
to CSA items. --- 17 rev1]
Fasteners with yield strength ≥ 210MPa (stainless steel)
Bolts type : M5*0.8, M6*1, M8*1.25, M10*1.5, M12*1.75 (Tolerance Fit 6g)
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 main-
tained.
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. Refer to the
enclosed wiring diagram.
External ground connection: The ground lug is located on the centre of cable entries.
For more information, refers to the Appendix Ⅲ (Grounding)
[Stainless steel name plate for the flame proof and dust ignition proof type shall be permanently
attached by rivets or screw on the cover. ----- 20 Rev0]
