The cble must be suitble for the working temperture s specified in the sfety instructions delivered with the first supply of the products. Additionl equipotentil grounding cn be lso performed by the user on the externl fcility provided on the solenoid cse. Minimum section of externl ground wire = 4 mm. Minimum section of internl ground wire = the sme of supply wire. In order to rech the terminl bord inside the solenoid, the top plte of the solenoid must be removed.
