MOUNTING
CONNECTION DIAGRAM
The SRP-22 roller blind controller is designed to be mounted in a junction box. Its dimensions en-
able both flush (Ø60 minimum) and surface mounting. In case of a flush junction box, a deepened
box is recommended, as it makes mounting easy with a large number of wiring.
The device is designed for a single-phase installation and must be installed in accordance with
standards valid in a particular country. Installation, connection and control should be carried out by
a qualified electrician staff, who act in accordance with the service manual and the device functions.
For safety reasons, do not mount the device without casing or with a damaged one, as an electric
shock may occur.
CAUTION: Before installation make sure the connection cables are not under voltage. The
cruciform head screwdriver 3,5 mm should be used to install the device.
1. Disconnect power supply by the phase fuse, the circuit-breaker or the switch-disconnector com-
bined to the proper circuit.
2. Check if there is no voltage on the connection cables by means of a special measuring equip-
ment.
3. Connect the device cables with the terminals in accordance with the installing diagram.
4. Install SRP-22 in a junction box.
5. Switch on the power supply from the mains and check if the device operates properly.
In case of control by means of the EXTA LIFE system transmitters, it is necessary to programme
transmitters and receivers earlier (see Programming transmitters). In case of driver cooperation
with a controller, it is also necessary to pair it earlier (see Driver’s registration in the EXTA LIFE
system). In case a double push-button switch is connected to the local input, it is ready for an im-
mediate operation.

MOUNTING REMARKS
1. Do not mount receivers in a close proximity to each other (if there is a possibility, keep a dis-
tance of minimum 15 cm between the devices). Particularly, avoid installation of one receiver
over the another.
2. The controller cooperates with one-phase 230 V AC motors, limit switches and overload switch-
es. More than one motor must not be connected to a single SRP-22 controller. It is absolutely
important to obey the maximum load – 350 W (2 A) for loads in class AC3.
