2 Product overview
2.1 Introduction
Fig.1: KM4602
The KM4602 analog output terminal has two potential-free analog outputs (0 to 10VDC). Both outputs are
internally connected to a common ground.
For each channel a switch enables selection between automatic and manual mode:
• In automatic mode, an analog value is output as a function of the process data.
• In manual mode, the value set via the potentiometer is applied to the output.
The 24VDC (UL) Bus Coupler supply voltage is also required for manual mode.
The state of the switches can be read by the controller (bit 0 of the status bytes).

3 Mounting and wiring
3.1 Recommended mounting rails
Terminal Modules und EtherCAT Modules of KMxxxx and EMxxxx series, same as the terminals of the
EL66xx and EL67xx series can be snapped onto the following recommended mounting rails:
• DIN Rail TH35-7.5 with 1mm material thickness (according to EN60715)
• DIN Rail TH35-15 with 1,5mm material thickness
Pay attention to the material thickness of the DIN Rail
Terminal Modules und EtherCAT Modules of KMxxxx and EMxxxx series, same as the terminals of
the EL66xx and EL67xx seriesdoes not fit to the DIN Rail TH35-15 with 2,2 to 2,5mm material
thickness (according to EN60715)!
3.2 Mounting and demounting - terminals with front
unlocking
The terminal modules are fastened to the assembly surface with the aid of a 35 mm mounting rail (e.g.
mounting rail TH 35-15).
Fixing of mounting rails
The locking mechanism of the terminals and couplers extends to the profile of the mounting rail. At
the installation, the locking mechanism of the components must not come into conflict with the fixing
bolts of the mounting rail. To mount the recommended mounting rails under the terminals and cou-
plers, you should use flat mounting connections (e.g. countersunk screws or blind rivets).
WARNING
Risk of electric shock and damage of device!
Bring the bus terminal system into a safe, powered down state before starting installation, disassembly or
wiring of the Bus Terminals!
Mounting
• Fit the mounting rail to the planned assembly location.
and press (1) the terminal module against the mounting rail until it latches in place on the mounting
rail (2).
