WARNING
Grounding
Connect mains protective earth wire to PE terminal in accordance with diagram (due to
class 1 power supply).
Mechanical counter
Connect a 1000 µF capacitor (capacitor+ to terminal 56 and capacitor- to terminal 58) if a
mechanical counter is connected to terminals 57 and 58 (active output).
Output cables
Use screened cables if long cables are used in noisy environments.
Digital output
If internal resistance of a load exceeds 10 kΩ, connect an external 10 kΩ load resistor in
parallel to this load.
WARNING
Intrinsically safe terminals
Always ensure that distance between cables/wires is minimum 50 mm in order to avoid that
wires/terminals of intrinsically safe circuits get into contact with wires of other cables.
Fasten cables/wires in a way that they cannot get into contact with each other, not even in
case of an error. Keep wire ends as short as possible.
5.2 Connection of add-on modules
When the add-on module has been installed, the electrical connections are available on
terminal rows 91-97.
