Local communication
interface (LKS)
Only for connection to a programmer outside the potentially
explosive area.
IMPORTANT (NOTE)
• The local communication interface (LKS) may only be operated at Um ≤ 30 V DC outside
the potentially explosive area.
• The equipment may only be used as a II 2 D type device in areas where the level of
mechanical danger is "low".
