(c) Whether the overall control system (control, manipulation, display, notification etc) is
working
(d) Operation and display of auxiliary instruments
(e) Presence of vibration and its intensity.
(f) Inspection of the wiring inlet.
①Whether metallic wiring material suitable to the conduit tube screw section
specifications are used.
②Whether sealing has been installed on conduit cable sections requiring explosion-
proofing.
③The compound must be filled at a sufficient depth and the attachment and hardening
state must be acceptable.
④The state of the attachment of the electronic instrument must be acceptable.
(g) Inspection of connection area between wiring and electric instrument etc.
①Proper access of terminal sign, polar circuits.
②The connection area must be sufficiently tight and measurement must be made to
prevent loosening.
③Connection section without terminal blocks etc must be clearly insulated.
(h) Inspection of container cover
①There must be no damage or foreign matter on the cover access section or screw threads
and it must be coated with non-hardening oils.
②When packing is used for dust and water proofing, it must be installed properly.
③The screws must not be faulty and sufficiently tightened.
(i) The state if operation based on explosion-proof structure and conditions of use must be
acceptable
