For this connection cables with a transversal section of 1.5 mm² to 4 mm² are
allowed to be used only.
The terminals no. 19 and 22 according to the connection plan are not used and must
not be connected.
1.4.5 Cable Shield
The cable shield of the LAN cable respectively the earth lead of the DC power cable
have to be connected to the terminals no. 6 respectively no. 7. The cable shield of
the LAN cable must be isolated according to the respective installation regulations.
The standard IEC/EN 60079-14 must be respected.
The conductive shield of the network cable has to be handled in the following way:
•
The cable coating of the network cable has to be striped.
•
The single conductor and the cable screen have to be separated.
•
The cable screen has to be drilled to a common conductor. When indicated
existing screen foils and auxiliary wires have to be removed.
•
Suitable isolating tube has to be pushed over the drilled cable screen. The
total length should not be longer than necessary for a secure arrangement of
the wiring.
•
The bare end of the drilled cable shield may be connected directly (The
terminals are approved for connecting flexible wires) or otherwise connected
with a mounted end sleeve for strands.
•
Advantageously these cable works should be done before inserting the cable
into the housing.
