Electrical connections
6 Electrical connections
Electrical connection must only be made by
qualified specialist personnel
The electrical installation must only be performed
by specialist personnel with the corresponding
qualifications.
Configuration
Switch on the control extension with the main switch
and perform the configuration of the heating system
according to the relevant instructions.
Requirements
Observe the standard and special regulations of local
power supply companies.
For full separation according to the setup require-
ments, a separating device of overvoltage
category III must be installed in the permanent
electrical installation. In most cases, these require-
ments are fulfilled with a circuit breaker, for example.
For speed-controlled pumps (controled via PWM-
signal), the maximum cable lengths of the pump
manufacturer must be observed.
DANGER!
Electric shock
There are live parts on the circuit boards. If
touched, they can cause injury and
property damage.
Before beginning any work, isolate the system
completely from all power sources, ensure that it
cannot be switched back on, and verify that it is
safely isolated from supply.
CAUTION!
Flexible stranded conductors
If flexible stranded conductors are not used for the
wiring, the contacts in the plug connections will be
subjected to excessive mechanical strain. In this case,
the warranty for the electronics would become null and
void.
Only flexible stranded conductors may be used for
the wiring.
