HAZARD!
Hazard via remote access
Depending on the form of realisation, hazards may be
created from remote access to the eco mode function.
Potential consequence: Injury,
material damage.
 Release of remote access to the eco mode function
is expressly PROHIBITED for all applications in
which the safety of persons, animals, and property
is not completely guaranteed at all times and under
all circumstances; especially for remote access.
 Safety is exclusively in the system operator's
sphere of responsibility.
 The controller manufacturer disclaims all liability.
The following safety settings are available:

Electrical connection

Required user qualification:
ELECTRICAL SPECIALIST
The electrical connection for eco mode may only be
performed by an ELECTRICAL SPECIALIST as
defined in the chapter User qualification.
IMPORTANT NOTICE!
Do not exceed the maximum currents
Do not exceed the maximum permissible electrical
currents for each individual relay switch output (max. 4
A) and for the sum of all relay switch outputs being
used in 230 V~ configuration (in sum, also max. 4 A)
Please also refer to the Chapter 230 V~ Power supply.
Depending on how eco mode is realised, there are various options for
establishing the electrical connection (volt-free, 230 V~,...).
In general, the connection options already described for the universal
switch outputs are available, see Universal switch outputs
connection options.

32 Universal switch inputs IN 1 ... IN 4
PoolManager provides four universal switch inputs that can be
®
connected to external volt-free switches or switch contacts:
Universal switch
input Description
IN 1 [6] Switch input IN 1 [terminal block 6]
IN 2 [7] Switch input IN 2 [terminal block 7]
IN 3 [8] Switch input IN 3 [terminal block 8]
IN 4 [9] Switch input IN 4 [terminal block 9]
Several of the potential applications are described in connection with
the various add-on functions, e.g. connection of an external switch or
push-button.
IMPORTANT NOTICE!
Volt-free inputs
The externally connected switch or switch contact
absolutely must be volt-free (free of electrical potential).
Otherwise, residual currents may arise, which can,
among other things, destroy electronic components.
The following figure shows the internal wiring of the input IN 1. The
other inputs IN 2 ... IN 4 are set up identically.
