5.3 Wiring Requirements
Cables in the PCS can be classified into power cables, control cables and communication
cables.
Power cables and communication cables should be laid in different cable supports with a
distance greater than 200mm. Avoid long parallel runs of the two kinds of cables to decrease
electromagnetic interference.
When communication cables and power cables cross, ensure that they are perpendicular to
each other. Do not run extra cables through the PCS.
The following is the recommended minimum distances between different parallel lengths of
shielded communication cables and power cables.
Parallel length (m) Min. Distance (m)
200 0.3
300 0.5
500 1.2
Data cable must be routed as near to the ground or supports (i.e. support beam, steel chan-
nel or metal rail, etc.) as possible.
5.4 Cable Protection
It is necessary to protect communication cables and power cables.
• Protection of communication cables
Communication cables are thin and easily broken. Lay power cables first and then com-
munication cables.
Communication cables should be laid in cable trenches or cable support arms and tight-
ened up by cable ties.
Avoid heating elements and cables with strong electric field when routing.
• Protection of power cables
Strong electric currents are present in the power cables. Protect the insulation layer from
scratches and damages.
Fix the power cable properly.
