Electrical connection
Check that the power supply is switched off prior to electrical connection!
1. Strip off approximately the last 7 cm of the inflow line »A1«.
2. Loosen the screw of the inspection flap and remove the flap.
3. Push the connection cable from below through the cable opening in the lower part
of the housing and fix it with the strain relief »A2«. The cable sheath must reach
into the strain relief.
4. Strip the insulation from the individual wires and connect them to the terminals
according to the wiring diagram. The appliance must be connected to the protec-
tive earth conductor.
5. Replace the inspection flap and secure it with the screw. If necessary, enlarge the
cut-out opening for the connection cable using a blunt tool.

Modbus connection (optional)
Check that the power supply is switched off prior to electrical connection!
1. Loosen the screw of the inspection flap and remove the flap.
2. Break out the opening for the Modbus cable in the inspection flap using a blunt tool.
3. Strip approx. 3 cm of the Modbus cable and fold the shielding »5« back over the
sheath (fig. E4).
4. Strip the insulation from the individual wires "B1" and connect the wires of both lines
5
in pairs to the Modbus plug according to their function.
5. Insert the Modbus plug into the socket on the unit.
6. Fix the cable with the strain relief »B2«. The sheath and the shield must reach into
the strain relief. The shielding of both cables must be fixed and connected by the
strain relief.
7. Open the cut-outs in the inspection flap for the wiring with a blunt tool, replace the
flap and fix it with the screw.
Note: If the ISX is the last appliance on the bus line, the signal line must be terminat-
ed with a 120 Ohm terminating resistor. To do this, connect a wired resistor in parallel
to the cable cores at terminals 3 and 4.
