Operating components

The following illustration shows that connection components and operating compo-

nents of power repeaters with an intrinsically safe interface:

The field bus terminator must be turned on the host side (Position 1) if the power re-

peater is the last instrument on the non-intrinsically safe segment of the field bus.

Switch S2 below the LEDs should be placed in Position I if the host has the function

of supplying power. This setting corresponds to the state of the product as supplied.

If the host does not make any power feed available for field devices, the switch must

be set in Position II. The power repeater then works as the power feed source and

supplies power to field bus devices connected to this H1 bus segment.

Subject to reasonable modifications due to technical advances.
