Warning
Danger from line voltage
If the housing is not perfectly sealed, there is a danger to life due to the line voltage if the
SCALANCE W786 is subjected to spray water or dampness. Make sure that you keep to
the following safety rules.
• Before connecting up, turn of the power supply.
• The sealing of the cable feedthroughs of the SCALANCE W786 is only assured when
the cable has a suitable diameter and adequate tensile strength. Only use cables that
meet the specifications in the section "Cables for the SCALANCE W786". When
connecting up a FO cable, make sure that you use the sealing sleeve supplied with the
SCALANCE W786.
• Never wrap insulating tape, adhesive tape or other materials around thinner cables to
achieve the required diameter. In this case, neither the housing seal nor the strain relief
clamps can fulfill their function.
• Close all unused openings in the housing seal with the sealing plugs supplied with the
SCALANCE W786. Do not use fillers or any other material under any circumstances.
