Controller's Electric Connection - OEG KSW-E Serie Mode D'emploi

CONTROLLER'S ELECTRIC CONNECTION

Each project with differential controller needs to base exclusively on customer
design and calculations and needs to be in compliance with valid rules and
regulations. Pictures, diagrams and text in this manual are intended solely as
an example and the manufacturer does not accept any responsibility for them.
If you use content of this manual as a base for your project, then you carry also full re-
sponsibility for it. Responsibility of publisher for unprofessional, wrong and false infor-
mation and consecutive damage are explicitly excluded. We retain the right for technical
errors, mistakes, changes and corrections without prior notice.
Installation of controlling devices should be done by an expert with suitable qualifications
or by an authorised organisation. Before you deal with the main wiring, make sure that the
main switch is switched off.
You have to follow the rules for low-voltage installations IEC 60364 and VDE 0100, law
prescriptions for prevention of accidents, law prescriptions for environmental protection
and other national regulations.
Before you open the housing make sure all poles of electric supply are disconnected. Not
following the rules this may lead to serious injuries such as burns or even risk of death.
The controller must be connected to the power supply via a separating switch for all
poles. The distance between poles by open contact must be at least 3 mm.
The relays R2 and R3 sre designed as semi conductor relays for pump speed control.
All low-voltage cables, such as temperature sensor cables, have to be routed separately
from mains voltage cables. All connections of temperature sensors are carried out to the
left, and main voltage connections to the right side of the controller.
