Overview

1.1 How to use this component operating manual
Structure of the IQ SENSOR NET operating manual The IQ SENSOR NET operating manual has a modular structure like the IQ SENSOR NET itself. It consists of a system operating manual and the operating manuals of all the components used.
Please file this component operating manual into the ring binder of the system operating manual.
1.2 Features of the combi output module
General characteristics
The combi output module has three current outputs and three relay outputs. You can link current outputs and relay outputs to sensors. The linked current outputs and relay outputs can, for example, be used to monitor sensors or to output measurement data. Unlinked relay outputs can be used for general monitoring functions.
With the standard MIQ module housing, the combi output module has the same characteristics as all MIQ modules regarding stability, leakproofness and weather resistance. It also provides the same wide variety of installation options (stacked mounting, canopy mounting, tophat rail mounting, etc.).
Instrument types
The MIQ/CR3 and DIQ/CR3 combi output modules differ in their compatibility with the individual IQ SENSOR NET system families.

Terminal strip
The combi output module has the following electrical connections on the terminal strip inside the housing:

• 3 x relay contact
• 3 x current output
• 2 x SENSORNET connection

3.4 Installation in the IQ SENSOR NET
The IQ SENSOR NET provides a number of options for integrating the combi output module mechanically and electrically in the system (stacked mounting, distributed mounting, etc.). The various types of installation are described in detail in the INSTALLATION chapter of the system operating manual.
3.5 Electrical connections: General instructions
Cable glands
All electric cables are fed from below via prepared openings in the enclosure of he module. Cable glands with different clamping ranges are included with the module to provide sealing between the cable and enclosure as well as for strain relief. Select the matching cable gland for the respective cable diameter:

• Small, clamping range 4.5 to 10 mm. This cable gland is suitable for all IQ SENSOR NET sensor cables.
• Large, clamping range 7 to 13 mm. This cable gland is required for cable sheaths with an outside diameter of more than 10 mm and is screwed into the enclosure via an extension piece.

If necessary, you can order more large cable glands in a set of 4 pieces (Model EW/1, Order No. 480 051).
General installation instructions
Observe the following points when attaching connecting wires to the terminal strip

• Shorten all wires to be used to the length required for the installation
• Always fit all the ends of the wires with wire end sleeves before connecting them to the terminal strip
• Any wires that are not used and project into the enclosure must be cut off as closely as possible to the cable gland.
• Screw a small cable gland with sealing ring into each remaining free opening and close it with a blind plug.

WARNING
No free wires are allowed to project into the housing. Otherwise, there is a danger that areas safe to contact could come into contact with dangerous voltages. Always cut off any wires that are not in use as closely as possible to the cable gland.
3.6 Connections to the relay and current outputs
WARNING
If external electrical circuits that are subject to the danger of physical contact are incorrectly connected to the relay contacts, there may be a danger of life threatening electric shock. Electrical circuits are regarded to be subject to the danger of physical contact when there are voltages higher than the Safety Extra Low Voltage (SELV).
Pay attention to the following points during installation:

• Electrical circuits subject to the danger of physical contact must only be connected by a qualified electrician.

• Electrical circuits subject to the danger of physical contact must only be connected when they are voltagefree.

• The terminal strip of the MIQ/CR3; DIQ/CR3 output module has two segments for relay outputs with three relay connections each (R1-R3 and R4-R6).
  If electrical circuits subject to the danger of physical contact are switched with a relay, no circuit that is not subject to this danger (e. g. the MIQ/CHV module) may be operated in the same output segment of the MIQ/ CR3; DIQ/CR3. For such applications use the second output segment of the MIQ/CR3; DIQ/CR3.

• Switching voltages and switching currents on the relay contacts must not exceed the values specified in chapter 6 TECHNICAL DATA. Protect electrical circuits against currents that are too high with an electrical fuse.

• Only single-phase consumers can be switched with the relays. Under no circumstances must multiphase consumers be switched with the aid of several relays (example three-phase current driven pumps). Always switch multiphase consumers via a protective relay.

• The MIQ/CR3; DIQ/CR3 may only be opened after the installation if all external voltages have been previously switched off.

Materials required

• Wire end sleeves, suitable for the connecting wires, with suitable crimping tool
• 4 x screwed cable gland with sealing ring (scope of delivery of the combi output module).

Tools

• Cable stripping knife
• Wire stripper
• Phillips screw driver
• Small screw driver

Connecting lines to the terminal strip

1. Open the module.

2. Screw the cable gland (pos. 1 in Fig. 3-1) with the sealing ring (pos. 2) into the module housing.

3. Loosen the coupling ring (pos. 3 in Fig. 3-1).

4. Feed the line through the cable gland in the module housing.

5. Connect the wires to the terminal strip. While doing so, pay attention to the specifications on the label located under the terminal strip.

6. Tighten the coupling ring (pos. 3 in Fig. 3-1).
   WARNING
   No free wires are allowed to project into the housing. Otherwise, there is a danger that areas safe to contact could come into contact with dangerous voltages. Always cut off any wires that are not in use as closely as possible to the cable gland

7. Close the module.
