Light Management Mains decoupler Standard / Universal

Operating Instructions
Mains decoupler Standard / Universal
1. Safety instructions
be carried out by a qualified electrician. When doing so, the
applicable accident prevention regulations must be observed. To
avoid an electric shock, isolate the device before working on it
(switch o circuit breaker). Failure to observe the installation
instructions can cause result in to the device, fire or other dangers.
Connect a 16 A circuit breaker upstream. The device is not isolated!
In the case of mains decoupling, a 230 V DC monitoring voltage is
present in the installation circuit.
2. Function
The mains decoupler is installed in a load circuit and decouples it from
the alternating current as soon as all devices of this load circuit are
switched off. This prevents alternating electromagnetic fields in sensitive
living areas and the related radiation caused by the building wiring
system. During mains decoupling a 230V DC monitoring voltage is
connected to the load circuit. The device is not isolated! In the decoupled
state, VDE-approved 2-pole phase checkers indicate the monitoring
voltage. As soon as a device is switched on, the mains decoupler
reconnects the monitored phase.A large number of common devices,
such as light bulbs, JUNG Tronic transformers, compact fluorescent
lamps or vacuum cleaners, are detected without additional base load
modules. The switching concept of the mains decoupler eliminates the
need for a manual calibration of the switch-on and switch-o threshold.
L If the load circuit contains continuous power consumers (e.g. a radio
alarm clock, telephone, alarm system etc.), the circuit is not
decoupled.
L The monitoring voltage present during mains decoupling supplies, e.g.
illuminated push buttons, up to a maximum of 8 mA.
L During mains decoupling the function of Blinds- or Radio Management
systems in the load circuit is limited.
L Only 1 control module per mains decoupler

3. Display and operating elements
FIG.A
(1) LED green: mains voltage decoupled only with Universal mains
decoupler NA7:
(2) 2 yellow LEDs as consumption display. If both LEDs light up, even
larger devices (> 50 W) are switched on. First the right, then the left LED
goes out.
(3) LED green: ready for operation
(4) Push button for switching mains decoupler on/off (
/ ).In the "On
(
)"position the mains decoupler automatically disconnects the power
circuit concerned from the mains supply when no device is switched on.
In the "Off (
)"position the power circuit is not decoupled.
