1) The column is valid at factory setting. The function must be programmed accordingly
with parameters Pn.12, Pn.13, Pn.62 and Pn.72 for F5 in operating mode GENERAL.
• Do not lay PTC cable of the motor (also shielded) together with control cable !
• PTC cable inside the motor cable only permissible with double shielding !

The function can be switched off with Pn.12 = “7“ (CP.28) if no evaluation of the input is
desired (standard in operating mode GENERAL). Alternatively a bridge can be installed be-
tween T1 and T2.
