S&P EB-100 HT Manual De Instrucciones página 19

If the installation is made to an individual ducting, use standard ducting of 100
mm diameter. Smaller diameter must not be used. If it is necessary to bend the
duct at the discharge of the fan, make the radius as large as possible.
Before fi xing the fan support (3), ensure that there are no obstructions to the
airfl ow, that the shutter mounted at the fan discharge opens easily and that the
impeller turns freely.
Fix the fan support to the wall with the 4 plugs and screws supplied in the pac-
kaging. Loosen the screws of cover (4) to gain access to the connection termi-
nals. Connect the electrical wiring as follows.
ELECTRICAL CONNECTION
The EB is an extractor designed for a single phase supply, with voltage and
frequency as indicated on the rating plate of the unit. The EB models are made
Class II (double electrical insulation) and the EB 12V are made Class III and
therefore they do not need an earth connection.
IMPORTANT: The safety isolating transformers CT-45/12 used with EB 12V
must be earth connected.
The electrical installation must include a double pole switch with a contact clea-
rance of at least 3 mm.
The electrical cable must be introduced to the EB through the slot (6) if the wire
is within the wall or through the cable entry (5 if the installation is made with a
surface mounted cable.
Once the cable has been introduced, proceed to the appropriate electrical wiring
depending on the EB model.
EB MODELS S
For these models use the following diagrams:

EB MODELS S (12V~50Hz)
For these models use the CT-45/12 safety isolating transformer:
