Installation Instructions
It is recommended to check the following points when receiving this product:
That it is the correct size.
That it is the correct model type (Single-phase or three-phase motor).
That the data on the rating label are those required (voltage, frequency etc).
The compatibility between the data on the rating label with the explosion proof stan-
dards, exhaust atmosphere, zone of use, ambient temperature and the temperature
listed (T1 to T6).
The installation and electrical connection work should be carried out in accordance
with all applicable national and local building code regulations pertaining to explosive
atmospheres and installations. All installation and electrical connection work must be
carried out by suitably qualified persons.
In case of using an increased safety motor, the installation must include a suitable
electrical protection device that disconnects the product from the electrical supply in
the case where the impeller is prevented from turning and temperatures beyond
those indicated on the rating label could be encountered.
All products must be installed in the fixing holes provided using suitably appropriate
screws or bolts accordingly. All products must be wired to the mains electrical sup-
ply in accordance with the enclosed electrical instructions. Before connecting the
electrical supply to the fan it is important to ensure that there are no obstructions to
the rotation of the impeller.
If the products are intended to be installed in an explosive atmosphere (*) that is
accessible to users then suitable guards/protection devices must be included in order
to comply with machinery directive 89/392/CE. For suitable guards/accessories
please consult the S&P General Catalogue or your nearest distributor accordingly.
