Controller's Electric Connection - OEG KSW series Bedienungsanleitung

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 regu-
lations. Pictures, diagrams and text in this manual are intended solely as an ex-
ample 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
information 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 quali-
fications 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 disconnect-
ed. 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.
For models KSW-E, KSW and KS2W are relays R2 and R3 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.
