4 Specil versions for fitting potentiometer Fitting potentiometer Certin types of ctutors re supplied redy prepred for fitting potentiometer. These ctutors differ from the sic type only in tht the housing is higher nd tht they re prepred for ccommodting potentiometer. ccessories re not required. The required type of potentiometer is to e ordered s seprte item (refer to «Ordering»). n tht cse, the third digit fter the dot in the ctutor s type reference will chnge from «1» to «2». Exmple: SQN sic type SQN version for fitting potentiometer Conversion y the user Users hve the choice of converting sic type of ctutor to version for fitting potentiometer. For tht, conversion kit type G32 is ville (refer to «Ordering»). Conversion of the sic type reference must e noted y the user on the ctutor s type field using permnent felt-tip pen. 4/17
