Operation- and
Assembly Instructions
1 Safety instructions
Electrical equipment may only be installed and fitted by electrically skilled persons.
Failure to observe the instructions may cause damage to the device and result in fire and
other hazards.
Danger of electric shock. Always disconnect before carrying out work on the devise or
load. At the same time, take into account all circuit breakers that supply dangerous
voltage to the device or load.
To ensure adequate contact protection, operate device only with the slide in use.
The radio communication takes place via a non-exclusively available transmission path,
and is therefore not suitable for safety-related applications, such as emergency stop and
emergency call.
These instructions are an integral part of the product, and must remain with the end
customer.

The range of a radio system from the transmitter to the receiver depends on various
circumstances.
The range of the system can be optimised by selecting the optimal installation location, taking
into account the structural circumstances.
picture 2: Reduced range due to structural obstacles
Example of penetration of various materials:
Material Penetration
Wood, Plaster, Plasterboard approx. 90%
Brick, Chipboard approx. 70%
Reinforced concrete approx. 30%
Metal, Metal grid approx. 10%
Rain, Snow approx. 1-40%
Intended use
- Reception of radio telegrams and conversion into wire-bound data
- Activation of RMD radio actuators, e.g. switch actuators, dim actuators or shutter actuators
- Installation in distribution boxes on DIN rail according to DIN EN 60715
Product characteristics
- Up to 30 RMD radio actuators can be connected
- Integrated antenna
- External antenna can additionally be connected in case of disadvantageous installation
conditions, e.g. metallic distribution boxes

4 Information for qualified electricians
4.1 Fitting and electrical connection
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before carrying out work on the device or load, disengage all the
corresponding circuit breakers. Cover up live parts in the working environment.
Connecting and mounting the device
Maintain a distance of at least 1 m between transmitter and receiver in order to prevent
overmodulation of the receiver.
picture 3
o Mount radio receiver (1) on DIN rail.
o Connect radio receiver according to connection diagram (picture 3).
o Connect radio receiver with the RMD radio actuators via the connection socket (3) using a
bus cable (6).
o Connect option external antenna (see Connecting an external antenna).
i The total length of the bus cables between the RMD devices may not exceed 3 m.
i The polarity of the bus cables must not be reversed.
i For the bus cable, use a shielded cable with twisted conductors and a conductor diameter
of 0.8 mm that is designed for a test voltage of 2.5 kV AC. Examples of permissible bus
cables are YCM 2×2×0.8 or J-Y(St)Y 2×2×0.8.
o Switch on mains voltage.

A Routing outside the distributor
B Routing inside the distributor
o Insert the antenna connector (7) into the SMB socket (2) of the radio receiver (1)
(picture 4).
o Route antenna out of the distributor providing reliable isolation.
To route the cable for the external antenna in the distributor, proceed as follows:
o Unlock the black slide (4) by pulling up on the end of the bow and pull out slide (picture 4).
o Insert the antenna connector (7) into the SMB socket (2).
o Route antenna out of the distributor providing reliable isolation.
o Re-insert black slide until it engages noticeably.
i The slide fixes the cable in place and ensures that the maximum installation height in the
distributor is maintained.
