1 Safety instructions
Electrical devices may only be mounted and connected by electrically skilled
persons.
Serious injuries, fire or property damage possible. Please read and follow manual
fully.
Danger of electric shock. Always disconnect before carrying out work on the device
or load. In so doing, take all the circuit breakers into account, which support danger-
ous voltages to the device and or load.
Danger of electric shock. Automatic RMD is not suitable for disconnection from sup-
ply voltage because mains potential is even present at the load when the device is
switched off. Always disconnect before carrying out work on the device or load. To do
so, switch off all associated circuit breakers.
Do not connect automatic RMDs in parallel. Damage to devices may result.
Use pulse insert exclusively for activation of the automatic RMD.
This manual is an integral part of the product, and must remain with the end cus-
tomer.
2 Intended use
Intended use of automatic RMD
– Manual or automatic switching of light in stairways
– Installation in sub-distribution units on DIN rail according to DIN EN 60715
– Switch on using pulse insert or push-button
The automatic RMD can also be used with pulse inserts from the light man-
agement.
Intended use of pulse insert
– Manual or automatic switch-on of an automatic RMD
– Mounting in appliance box with dimensions according to DIN 49073
– Operation with suitable LB-Management cover, see accessories
Automatic switching of light
The pulse insert is combined with a motion detector cover. As soon as the brightness
drops below a value set on the motion detector cover and motions are detected, the
pulse insert sends a switch-on signal cyclically to the automatic RMD. The latter
switches on the light for the set run-on time. After the run-on time has elapsed, the
automatic RMD switches the light off. After switch-off, pulse inserts with motion de-
tector covers will not detect any motions for approx. 3 seconds.
