ASSEMBLY CAUTION
NEVER CONNECT/DISCONNECT UNDER POWER SUPPLY/IN PRESENCE OF DUSTS ATMOSPHERE
NEVER OPEN THE ENCODER
The customer obliges to take up and to use our products, according to our specifications and to the manners of the profession. Our
company would not be responsible for any defect resulting from a defective or erroneous assembly. From a use superior to the
standard, or in abnormal conditions. The breakdowns resultant of shocks, bad electric supply, put in low capacity or overcapacity of
the product, the environment of bad conditions (humidity, projection, dust, etc) cannot be imputed to us. The converter doesn’t
require any maintenance. Any encoder presenting a dysfunction will have to be the object of immediate return for control in our
facilities. The encoder mustn’t be open in any case (cable gland and/or cover)
An earth situated on the cover must be linked with the ground of the installation
