Tips and advice that make the work easier.

2. Applications

The IO 50 SQFlex switch box is made for solar-powered SQFlex systems and

is an on/off switch for the system power supply.

In addition, the IO 50 functions as a connection point for all necessary cables.

By means of the on/off switch, it is possible to

• start/stop the pump

• reset alarms.

The electrical connection and protection must be carried out in accordance with

local regulations.

3. Installation

WARNING

Death or serious personal injury

‐Before starting any work on the IO 50, make sure that the power

supply has been disconnected and that it cannot be accidentally

connected.

3.1 Mechanical installation

The IO 50 SQFlex must be placed on a firm and stable surface that fits the box.

3.2 Electrical connection

The electrical connection must be carried out by an authorised electrician in

accordance with local regulations.

Two typical wiring diagrams are shown in section A.1. Appendix:

• one DC conductor earthed (fig. Wiring diagram, one DC conductor earthed)

English (GB)

• floating DC supply or AC connection (fig. Wiring diagram, floating DC

supply or AC connection).

Position of wire jumpers

Wiring Place the wire jumpers between

One DC conductor earthed 1L1 - 3L2 5L3 - 7L4 4T2 - 6T3

Floating DC supply 1L1 - 7L4 3L2 - 5L3 -

Explanation

The jumpers are necessary in order to meet the demands of the circuit breaker

due to the complexity of handling DC currents. This means that contact sets in

series connection are required.

WARNING

Death or serious personal injury

‐Never make any connections in the IO 50 unless the power sup-

ply has been disconnected. The IO 50 must be connected in ac-

cordance with the rules and standards in force for the application

in question.

‐Use appropriate compression fittings to ensure watertight cable

entries.

‐The IO 50 must be earthed.

The DC supply voltage is stated on the nameplate. Make sure that the IO 50 is

suitable for the power supply on which it will be used.

English (GB)
