Instructions on electrical
connection of thermos
All and any installation work shall be performed by specialist or authorised
personnel only. General regulations as well as the local regulations of the
electricity provider must be observed.
Instructions:
•
The electrical connection shall be: 230 V, 50 Hz
•
Never install 230 VAC cables and control or sensor lines next to each other or in the
same cable duct, because this might cause parasitic induction and disturb the sensor
elements. A minimum distance of 20 cm (8 inches) is recommended.
•
Install the control unit in a way to ensure there is no heat build-up and sufficient
space for service access. Never enclose or “bury” the control unit (e. g. no flush
mounting).
•
The internal temperature sensor of the programmer must record the temperature of
the room air.
•
Lay all cables in a conduit or cable duct. Use conduits also in wall penetrations.
•
For cable installations by the customer, the cable types specified in the table, or
equivalent types, shall be used.
•
When installing temperature sensors (especially inside a duct), never attach any
sensor in the region of the shrink sleeve.
•
Make sure the system is de-energised before making or removing any plug-in
connections.
