SystemDescription

5.1.2

Application area

The Power I/O Box Type 8643 is designed for remote use in an industrial environment, particularly in the areas of
the pharmaceutical industry, petrochemistry and fine chemistry.

It satisfies the conditions for protection class IP65 (in aluminium or polyester body).

DANGER!

Risk of explosion from electrical voltage!

The Power I/O Box Type 8643 is designed as ignition protection type Ex-e (increased safety).

▶

Before working on non-intrinsically safe circuits of the Power I/O Box Type 8643, always switch off the oper-
ating voltage of the system!

If using the Power I/O Box Type 8643 in a control cabinet, ensure that

• the control cabinet is also authorized for use in an environment where there is a risk of explosion,

• the control cabinet is large enough for the lost heat to be discharged to the exterior in a suitable

manner,

• the internal temperature of the control cabinet does not exceed the allowable operating temperature of

the Power I/O Box Type 8643!
