Installation and Operating Instructions

SDC 306 1316BED036-11B-E Date 06/09

- 10 -

General attachment regulations:

• For all attachment wires, cut the wire

sheath to a length of approx. 6 – 8 cm

and unisolate the wires by approx. 10

mm from the ends.

• In the case of flexible cables, provision

must be made inside or outside the

device for strain relief. The wire ends

must be fitted with wire-end sleeves. If

necessary, PG9 screw fittings can be

used for the feedthrough on the 230 V

side.

• The wires are fed into the device

through the designated openings.

• All earth wires must be fixed in the

terminals indicated with “PE” (Earth

potential).

6.1

230 V connections

The following points must be observed for

the 230 V connections:

• Where there is a fixed mains

connection, it must be possible to

interrupt the mains supply to the control

unit outside the control unit by means of

a switch.

Where the mains connection is effected

by means of wire and plug with earthing

contact, this switch may be dispensed

with.

• The control units are designed for

operation with a 230 V /50 Hz mains

supply. The pumps and valves to be

connected must be designed for this

voltage.

• All earth wires must be connected to the

terminals marked PE.

i

The neutral terminals (N) are electrically

connected and are not switched.

i

The switching output (A4) is potential-

free.

i

The switching outputs (A1/A2/A3) are

230 V closers.

6.1.1 Overview: 230 V connections for SDC 306

The table below shows the allocation of

switching outputs for the different system

types. The fields with a grey background are

essential to the basic functions of the

system. The white fields are designed for

optional additional functions.
