CamCon DC16
3. Installation
The device is snapped onto an "EN - carrier rail" in the switchboard (see chapter "3.1. Dimensions" on
page 14). The grounding connections and the cable coverings are to be put on the shortest possible
way on the serial grounding clip next to the device. The grounded assembly plate and its electrical
connection to the "EN carrier rail" allow an excelent grounding of the disturbances onto the covering.
All cable connections are to be switched in a cold state ! If your CamCon has an external interface, it is
connected to the
"ext.Int. IN"
plug at the CamCon module (e.g. DAC16, DC16/IO, DC91/IO or DC92/I)
with a cable of the type: KKyy/IO-XX (yy = CamCon Type / XX = Length in meters). The data lines of
the external interface are galvanically separated through an optical coupler, they have to be covered,
and the cover has to be grounded on both ends. The connection cable (for the measuring system or
the serial interface) also has to be covered, and the cover has to be grounded on both ends. Analog
signals have to be covered, and the cover has to be grounded on one end.

To guarantee a maximum of EMV protection against
disturbances in encoder cables (SSI - measuring system) in
strong electromagnetic machines, the illustration to the right
demonstrates in a connection example, how the high EMV
resistance of the CamCon DC16 can still be increased.
Here the device grounding and the cover connection of the
encoder cable are put directly on a serial grounding pin located
left
of the CamCon. Through the grounded assembly plate and
its electrical connection to the EN - carrier rail, we reach a
maximum deflection of the disturbances onto the mantling of
the encoder cable.
The second flat plug next to the status LED of the CamCon
remains unswitched.
