WARNING
• Do not apply input voltage exceeding the maximum input voltage or allowable
common mode input voltage.
• To prevent electric shock, be sure to furnish protective earth grounding of the SL1400.
• To prevent electric shock, be sure to fasten the module screws. Otherwise, the
electrical and mechanical protection functions will not be activated.
