Function of wire-hook switches
For closing the wire-hook switches, release the locking screw, withdraw the instrument module from the housing and
close the wire-hook switch. Re-insert the instrument and lock it.

The unit contains electrostatically sensitive components. Comply with rules for protection against ESD during mounting.
Wire-hook switch S:
The switching status is signalled by function STATUS and can be used in the engineering for blocking e.g. operating
pages and other settings.
Wire-hook switch for PROFIBUS DP (Option B):
The bus terminating resistor can be connected by 2 wire-hook switches (DP) in KS98-1.Both wire-hook switches must
always be open or closed .
Wire-hook switch for CAN bus: (only Option CANbus):
Both ends of the CAN bus must be terminated (wire-hook switch closed).
Wire-hook switch for transmitter supply
Versions (KS98-11x-xxxxx) with transmitter supply are provided with a potential-free supply voltage for energization of
a 2-wire transmitter, or of max. 4 control inputs.
The output connections can be made to terminals A4(+) - A1(-) by means of 3 wire-hook switches.
If A14/A12 is used for di1/di2, A12 must be linked with A1.
