Safety and
Environment
■ Pay special attention to prevent any impact on the device during transportation or
assembly.
■ Pay attention to prevent any damage to any packing when transporting or mounting
the machine to the vessel.
■ External ground is located on top of cable entry, and the grounding wire to connect external
ground must be 4㎟ (4mmSQ). (Internal ground is connected before shipment.)
■ Use the same standard flange or screw.
■ Make sure to insert washers between bolts and nuts to prevent loosening.
■ Make sure to insert gaskets between flanges. (Select the gaskets in consideration of
temperature of content and pressure of vessel.)
■ Install an Ex-proof product only in an Ex-proof zone.
Make sure to insert a washer if the terminal lug is removed from the ground
terminal and then re-connected. (Loosening prevention)
■ Use the cable gland connection or metal pipe line lead-in on the wire inlet, and use a
product with equivalent Ex-proof certificate to connect it with the external line lead-in
method.
■ For non-use external wire inlet, use a closed plug that passes safety certificate above
equivalent performance with the product.
