HAZARD!
Exceeding the permissible switching current
or the permissible contact voltage
The system current may not exceed 4A per switch
output. The maximal permissible switching contact
voltages are 230V~ and 30V DC.
Potential consequence:
Burning of conductor paths in PoolManager
®
•
Ensure that permissible current and permissible
voltage are never exceeded.
•
If applicable, secure the electrical circuits externally
in accordance with applicable stipulations.
•
If higher currents or voltages are needed, then an
external circuit breaker has to be used.
24.4.1.1
230VAC unit control
A 230V~ unit is connected between neutral conductor N (blue) and
phase L (brown) of the power supply, between which there is a voltage
of 230V~ (AC voltage). Additionally, there is generally also a protective
earth connection (yellow/green).
Should a unit of this kind be controlled via a PoolManager
®
universal
switch output, then it has to be connected as follows (Example for
switch output OUT 1):

Connection of neutral conductor N and PE
The controlled external system's neutral conductor N
and protective earth PE can be connected to the
terminal blocks intended for the purpose N

and PE as
shown in the figure.

Control of unit with
potential free control input
Some systems have a potential free control input. This can be
connected directly to the PoolManager
®
switch output.
If control input of this kind is available, then it should always be used
whenever possible instead of turning the external system's power
supply on and off.
The following figure shows how the connection of an external system
with potential free control input to the switch output OUT 1:
