Operating instructions, 07/2006, A5E00478463
•
Provide a mains disconnection device in the direct vicinity of the device (for load rating,
see type plate). It must be easily accessible and marked.
•
Check whether the existing mains voltage agrees with the mains voltage specified on the
type plate.
Caution
When wiring all electric lines, keep the heat radiation of the device in mind. Keep a distance
>2 cm away from the device housing.
3.4.2
Connection of the signal lines
Warning
Only connect the signal lines with devices which have reliable electric separation from their
power supply.
•
Connect the signal lines to the SUB-D plug connectors on the rear of the device.
•
The connection lines must be shielded to the relay outputs, the binary inputs, the analog
inputs and the analog output. Connect these to the corresponding trapezoidal plugs
(SUB-D plug connectors) in accordance with the routing assignments.
•
The reference ground of the analog inputs is the potential of the housing.
•
The analog output is floating.
•
The shielding of the interface line must be at the potential of the housing. Connect the
shield of the line to the shield of the SUB-D plug connector with high contact area. The
core cross-section must be ≥ 0.5 mm². The interface line may be at most 500 m long.
Note
All connection lines (except for the mains connection line) must be shielded. The
shielding of the connected lines must have a large-area and continuous contact at the
respective terminal pieces. The core cross-section must be ≥ 0.5 mm². We recommend
cables of type JE-LiYCY...BD. The cable length of the analog output depends on the
load.
