For your safety
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR
ARC FLASH
Safe electrical installation must be carried out only by skilled professionals. Skilled professionals must prove profound knowledge in the following areas:
• Connecting to installation networks
• Connecting several electrical devices
• Laying electric cables
• Connecting and establishing KNX networks
• Safety standards, local wiring rules and regulations
Failure to follow these instructions will result in death or serious injury.
RISK OF FATAL INJURY FROM ELECTRIC SHOCK
The output may carry electrical current even when the load is switched off.
• When working on the device: Always disconnect the device from the supply by means of the fuse in the incoming circuit.
• Even if the manual switch is in the „OFF“ position, a
KNX telegram can switch the connections to being live at any time. Before working on the device, always diconnect the fuse in the incoming circuit from the supply.
Failure to follow these instructions will result in death or serious injury.
The device may be damaged!
• Always operate the product in compliance with the specified technical data.
• Do not use the current detection function for applications relevant to safety.
• Connect only pure ohmic loads to a channel with direct current (DC).
• Only install devices with at least basic insulation next to the device.
Failure to follow these instruction can result in equipment damage.
Getting to know the switch actuator
The switch actuator REG-K/4x230/16 with current detection and manual mode (referred to below as the actuator ) can switch four loads via separate, floating make contacts.
You can also manually switch the connected loads with manual switches on the actuator without bus voltage.
The actuator has a bus coupler. It is installed on a
DIN-rail TH 35 according to EN 60715, with the bus connection made via a bus connecting terminal. It is supplied with power from the bus voltage. A data rail is not required.
The actuator also has integrated current detection which measures the load current of each channel.

¼ WARNING
Risk of fatal injury from electrical current. The device can be damaged.
Safety clearance must be guaranteed in accordance with IEC 60664-1. There must be at least 4 mm between the individual cores of the
230 V supply cable and the KNX line.

RISK OF FATAL INJURY FROM ELECTRIC SHOCK
Voltage may be present at the outputs when the mains voltage is connected to the system.
If subjected to strong vibrations during transportation, the switch contacts might change to the enabled state.
After connecting the bus voltage, set the relays of the channels to the position desired simply by switching
„On/Off“ or by changing the manual switch to „OFF“.
Failure to follow these instructions will result in death or serious injury.
The device may be damaged!
• Protect the switch contacts with a series-connected
16 A circuit breaker.
Failure to follow these instruction can result in equipment damage.
3 Connect the bus voltage.
4 Wait at least 30 seconds.
5 Set the relays of the channels to the position desired simply by switching "On/Off" or by changing the manual switch to "OFF".

7 Connect the mains voltage.
You can now check the function of the connected load using the manual switch, without having to load the application from the ETS. (See the "Operating the actuator" section.)
Commissioning the actuator
1 Press the programming button.
The programming LED lights up.
2 Load the physical address and application into the device from the ETS.
The programming LED goes out.
The operational LED lights up: The application has been loaded successfully, the device is ready to be operated.
Operating the actuator
Connected devices are usually controlled using pushbuttons or by remote control. However, you can manually switch each of the actuator's channels on and off directly at the manual switches.
What should I do if there is a fault?
The green operational LED "RUN" is not lit.
Cause
The bus voltage has failed.
Solution
Check bus voltage; only manual operation is possible.
The application was not loaded properly.
Load it again.
