Shutter Switch GE 521 5WG1 521-4AB02

1 x 230 V AC / 6A, 42 x 28 mm

Product and Applications Description

The GE 521 shutter switch has an oblong design and is

therefore suitable for mounting in devices or for sepa-

rate mounting. Via its four volt free contacts it can raise

and lower blinds and gradually adjust louvres.

One channel is provided for two actuators allowing to

control up to two blinds actuators.

The volt free contacts (one relay) can be assigned

various tasks depending on the application program

used, i.e. the shutter switch GE 521 consists of the

device (hardware) and its application programs (soft-

ware) for controlling venetian blinds.

With the ETS (EIB Tool Software) the application pro-

gram is selected, its parameters and addresses are

assigned appropriately, and downloaded to the shutter

switch GE 521.

Siemens AG GE 521, 4 pages Technical Manual

Application Programs

11 A1 Shu 510205

• allows controlling blinds/shutters

• single blinds/shutter control with safety mode

• drive mode (up or down) in case of bus voltage failure

can be set in the parameter list

• can be also used as a single binary read-out with

alternating contact

V WARNING

When using the shutter switch GE 521 for controlling

blinds actuators the instructions below must be followed

(failure to do so may result in the contacts welding):

• Do not use older application programs (e.g. 11 A1

Shutter 510202) anymore with the shutter switch

N 521, use 11 A2 Shutter 520205 instead.

• The factor and base values of the parameter "Re-

verse delay" must be combined to establish a time

period as given by the blinds manufacturer (usually >

500 ms).

• The parameter "on bus voltage failure" should be set

to "maintain current state" or "stop".

Installation Instructions

• The device may be used within casings or other

devices, or surface mounted.

V WARNING

• The device must be mounted and commissioned by

an authorised electrician.

• A safety disconnection of the device must be possi-

ble.

• Take care that 230 V devices that are used in combi-

nation with this device provide a basic insulation of

250 V to the line; otherwise a safety distance of 4 mm

must be kept.

If in doubt, extra insulation should be added.

• The prevailing safety rules must be heeded.

• The device must not be opened. A device suspected

faulty should be returned to the local Siemens office.

Mounting and Wiring

General description

The devices can be built into casings or mounted sepa-

rately with two screws, Ø 4 mm.

Opening the connection block compartment (Figure 2)

- Press the snap levers (A1) outwards (black arrows)

and remove the cover lids (A2) of the compartments.

Closing the connection block compartment (Figure 2)

- Press the cover (A2) down until it clicks into place.

Figure 2: Opening and closing the cover lids

Slipping off bus connection blocks (Figure 3)

- The bus connection block (B3) is situated in the left

connection block compartment. It consists of two

components (B3.2 and B3.3) with four terminal con-

tacts each. Take care not to damage the two test

sockets (B3.1) by accidentally connecting them to the

bus cable or with the screw driver (e.g. when attempt-

ing to unplug the bus connection block).

- Carefully put the screw driver to the wire-inserting slit

of the bus connection block's grey component (B3.3)

and pull the bus connection block (B3) from the built-

in device. When removing the red component of the

bus connection block, the grey component remains in

the compartment.

Note

Don't try to remove the bus connection block from the

bottom side! There is a risk of shorting-out the device!

Slipping on bus connection blocks (Figure 3)

- Slip the bus connection block onto the guide slot

- press the bus connection block (B3) down to the stop.

Connecting bus cables (Figure 3 “A“)

- The bus connection block (B3) can be used with

single core conductors Ø 0,6 ... 0,8 mm.

- Remove approx. 5 mm of insulation from the conduc-

tor (B3.4) and plug it into the bus connection block

(B3) (red = +, grey = -).

- The sheathing of the bus cable must be attached to

the casing of the built-in device via the conductor fix-

ing (B1). When using a cable with shielding, it can be

screwed onto the terminal (B7, Figure 3).

The recess (B2) can be used to accommodate an over-

voltage protection which is connected to the bus con-

nection block in parallel with the bus line (Figure 3).

Disconnecting bus cables (Figure 3 “A“)

- Unplug the bus connection block (B3) and remove

the bus cable conductor (B3.4) while simultaneously

wiggling it.

Connecting load circuits (Figure 3 “B“)

- The load circuit is connected to screwless plug-in

terminals (B4).

- Remove approx. 9 to 10 mm of insulation from the

wire (B4.1) and plug it into the terminal (B4).

- The sheathing of the bus cable must be attached

to the casing of the built-in device via the conductor

fixing (B8, Figure 3).
