Electric installation
DANGER DUE TO ELECTRICAL VOLTAGE!
Electrical installation must only be carried out by qualified personnel!
Before any electrical works are carried out, the power supply must
be switched off and secured against being reactivated!
ESD SENSITIVE!
The electronic components in the devices are sensitive to electrostatic
discharges. The generally accepted safety precautions for ESD-
sensitive devices must be observed when handling the devices.
The following applies, in particular:
Do not pull or plug in socket connections under voltage.
As the person handling the device, please discharge yourself electrostatically for at least 5
seconds prior to directly touching the devices, e.g., by touching a grounded part of the
system or by wearing an ESD antistatic wrist strap connected to ground.

The casing is equipped with an
easy lock-in
closure
. In order to open the display lid or the
small connection space cover, the side lid lugs
must be gently lifted outwards from the main
casing. The display lid can then be pulled
forward. The upper lid lugs run in guide grooves
up to the front lock-in position.
Afterwards, the display lid is raised. The display
lid can be supported on the main casing using a
standing bracket so that it remains raised for
work on the terminals.
In order to close the casing, the standing bracket
must be unlocked with a backward motion and
the lid closed by moving it downward. The
upper lid lugs must now be unlocked and the lid
pushed backward onto the main casing. In order
to ensure that it has been completely resealed,
press gently on the four corners of the casing.
The casing lid will close with a soft, audible click.
Please ensure that all of the lid lugs have been
securely bolted using the safety bolts each time.
The device must be supplied with continuous
voltage. I.e., the voltage supply must not be locked with the filter system.
A digital input is
available for interlocking the dosing with the swimming pool's filter system.
For electrical installation, see also wiring diagrams in the controller's terminal casing or in
Section 9.2.
