On TeSys D with coil AC/DC (LCxDxxBNE or LCxDxxEHE or LCxDxxKUE or LCxDxxUSE), no need to respect polarity when controlled in DC. The poles A1 and A2 are noted without sign + or -.
On TeSys D with coil DC only (LCxDBBE), the polarity shall be respected. The poles are noted A1+ and A2-. In case the connections are reversed, the contactor won't close. However, this misconnection won't destroy the contactor. Correcting the wiring will fix the trouble.
