Installing a cable grommet
An additional cable feed-through must be created in order to connect an external device (e.g. lighting) or an external sensor (e.g. paddle flow switch)
to the Salt Relax POWER. There are push-outs on the bottom and sides of the front housing cover of the Salt Relax POWER for this purpose.
Proceed as follows:
Select the push-out closest to the connecting terminal you wish to use.
Press from the inside against the centre of the push-out until you can see the round shape on the outside of the housing. Now press from
the outside against the centre of the circle. Repeat this step until the circular push-out is detached, leaving a round hole. If the hole is not
perfectly circular, you can round it off carefully using a suitable file.
Now place the gable gland in the hole from the outside and lock it in position from the inside with the cap nut.

Proceed as follows to feed a cable through the cable grommet:
Unscrew the nut of the cable gland until it is positioned on the very end of the thread. Alternatively, you can remove it completely.
Remove the plug, leaving the seal in the screw fitting.
Feed the cable through the nut and the cable gland into the clamping cavity. Make sure there is an adequate length of cable on the inside
of the housing cover.
Connect the cable as shown in the connection diagram.
Tighten the nut (without exerting excessive force) to achieve reliable sealing.

Installing the pH and redox module
In order to use the pH option or the redox option, the corresponding module must be inserted into the device.
To do this, proceed as follows:
Disconnect the Salt Relax POWER from the mains. It is not enough to simply switch the device off.
Remove the front cover of the Salt Relax POWER (see Removing the housing front cover)
Place the pH or redox module in the holder provided, as shown in the diagram. Observe the correct polarity.
Slot for pH module (PH)
Slot for redox module (RX)
Close the cover again (see Removing the housing front cover)
As soon as you reconnect the Salt Relax POWER to the power supply and switch it on, the software will detect the connected option and
display the associated menus at the corresponding points.
