Connecting the cables

Procedure

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 adhesive sealing foil 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.

WARNING

Danger from line voltage

If the supply cable of a power supply adapter for 100 – 240 VAC is disconnected from the

mains power, a dangerous voltage may be present for a brief period.

For this reason, do not connect the contacts of the supply cable to the mains power supply

using a plug-in connector but screw the contacts to a terminal block that can be

disconnected from the mains power by a switch.
