Schneider Electric MTN683816 SpaceLogic KNX Power Supply REG-K Instruction Manual

Schneider Electric MTN683816 SpaceLogic KNX Power Supply REG-K

Product Information

• The SpaceLogic KNX power supply REG-K with emergency power input provides bus line devices with power. It is available in three variations: REG-K/160 mA, REG-K/320 mA, and REG-K/640 mA. The power supply is short-circuit-proof, features a voltage and current limiter, and provides a stabilized safety extra-low voltage (SELV) of DC 30 V. It is equipped with an integrated choke to isolate the data telegram from the power supply.
• The power supply has several LEDs for status indication. The green LED (RUN) indicates that the power supply is ready for operation. The red LED (I>Imax) indicates excessively high output currents. The yellow LED (Battery) indicates that, in the event of a mains voltage failure, the bus voltage is supplied by the emergency power supply.
• The power supply is designed for installation on the DIN rail according to DIN EN 60715. It does not require a data rail. The maximum cable length between the power supply and the furthest bus device is 350 m.

Product Usage Instructions

Installing and Connecting the Power Supply Unit:

1. Place the power supply unit onto the DIN rail.
2. Connect the KNX bus to the appropriate terminals on the power supply unit.
3. Connect the mains voltage to the power supply unit.

Meaning of the LEDs:

• Green LED (RUN): Indicates that the power supply is ready for operation.
• Red LED (I >Imax): Indicates excessively high output currents.
• Yellow LED (Battery): Indicates that the bus voltage is supplied by the emergency power supply in case of mains voltage failure.

Note: It is important to ensure that live lines do not come into contact with unused terminals to avoid any hazards. Also, it is recommended not to connect any other power supply to the REG-K/640 mA power supply unit within one KNX line.

Accessories

• REG emergency power supply (Art. no. MTN683901)

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.
• The device may be damaged!
• All devices that are mounted next to the power supply unit must at least be equipped with basic insulation!
• Failure to follow these instruction can result in equipment damage.

Getting to know the power supply

• The SpaceLogic KNX power supply REG-K with emer-gency input (referred to below as the Power supply) provides bus line devices with power. At least one power supply is required per bus line. The integrated choke iso-lates the data telegram from the power supply.
• The power supply provides a stabilised safety extra-low voltage (SELV) of DC 30 V. It is short-circuit-proof, and features a voltage and current limiter. Excessively high output currents are indicated by a red LED (I>Imax).
• The bus devices on the connected line can be reset us-ing the reset key on the power supply. This status dis-played via the red reset LED. The green LED (RUN) indicates that the power supply is ready for operation. A yellow LED (Battery) indicates that, in the event of a mains voltage failure, the bus voltage is supplied by the emergency power supply.
• The max. cable length between the power supply and the furthest bus device is 350 m. The power supply is in-tended for installation on the DIN rail in accordance with DIN EN 60715. A data rail is not required.

Connections, displays and operating elements

• A Reset key with an integrated reset LED
• B Green LED: Operating display (RUN)
• C Red LED: Overcurrent display (l>lmax)
• D Yellow LED: Emergency power supply operating display (Battery)
• E Bus connection (with cover)

Installing and connecting the power supply unit

• WARNING Risk of death from electric shock. The device can become 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 A.
• HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Make sure that live lines do not come into contact with unused terminals (e.g. by using cable separating raceways).
• Failure to follow these instructions will result in death or serious injury
• The device may be damaged!
• Only approved devices may be connected to and operated using output “C + -“!
• The emergency power supply connection cable may have a length of max. 1 m and must be laid out as a SELV cable!
• Failure to follow these instruction can result in equipment damage.

1. Place the device onto the DIN rail.
2. Connect KNX.
3. Connect the mains voltage.

The green operating display lights up when the power supply is ready for operation.

Meaning of the LEDs

• The overcurrent display (I>Imax) lights up.
• The operating display (RUN) lights up.
• The output current is too high. Remove devices from the line until the total power consumption of the re-maining devices is less than the power supply unit’s nominal current.
• The device may be damaged!
• No other power supply should be connected up to the power supply unit REG-K/640 mA within one KNX line
• Failure to follow these instruction can result in equipment damage.
• The overcurrent display (I>Imax) lights up. The operating display (RUN) does not light up.
• Short circuit in the bus line. Switch off the mains volt-age for at least 30 seconds. Eliminate the cause of the short circuit. Then switch the power supply back on and press the reset key once.
• When the power supply is reset (Reset LED is lit up) the bus line is released for about 20 seconds.
• All other devices that are connected to the same line are then also reset.
• The emergency power supply operating display (Battery) lights up.
• Mains voltage failure. The bus voltage is supplied from the connected emergency power supply.
