Precautions for

ground connection

(explosion-proof

products)

■ When flanges or screws are used for fastening, the size should be the same.

■ The user should place a washer between each bolt and nut to prevent loosening.

■ When fastening flanges to each other, gaskets should be used.

(The gaskets should be selected considering the temperature of the content and the pressure of the

container.)

■ The user should install appropriate products after judging whether the products are to be used in

explosion-proof regions.

■ The power should be supplied when the installation has been completed and the cover has been

fastened.

Great impacts should not be applied to the product when the product is moved.

■ The user should use a cable grand connection method or a metal pipe wire lead-in method on

wire inlets, and when external wires are led in for connection, products that have been certified for

at least the same explosion-proof performance as the relevant explosion-proof equipment should be

used.

■ Plugs for closing that passed safety certification tests for at least the same performance as the

relevant explosion-proof equipment should be used for external wire inlets not used.

■ Ground connections are divided into external ground connections and internal ground connections.

In the case of external ground connections, the size of ground wires should be at least 4㎟ (4mmSQ).

■ Internal ground wires should be of the same size as the power cable and the size of internal grounding

terminal lugs should be 3.1㎟ (3.1mmSQ). If the power cable is larger than 3.1㎟, the terminal lug

should be taken out before connecting the ground wire.

When connecting a ground wire to an internal grounding terminal after taking out

the terminal lug, a washer should be used without failure (to prevent loosening).
