· The connecting cables to the nominal value outputs must not have more than one intermediate
terminal.
· If it is necessary to branch to physically separate servo inputs, the connection must be
made in a grounded terminal box. Suitable terminal boxes are available from HEIDENHAIN
(Id. Nr. 251 249 01).
· The chassis of the terminal box must be electrically connected with frame of the machine.
· The 0 V connection of the nominal-value-difference inputs must be connected with signal
ground. Required cross section ³ Ø 6 mm².
· Use only original HEIDENHAIN connecting cables and connecting elements.
