WARNING
• Do not apply input voltage exceeding the maximum input voltage or allowable common
mode input voltage.
• To prevent the possibility of electric shock, be sure to furnish protective earth grounding of
the DL850/DL850V.
• To prevent the possibility of electric shock, be sure to fasten the module screws.
Otherwise, the electrical and mechanical protection functions will not be activated.
• Avoid continuous connection under an environment in which the surge voltage may occur.
