Cabling
6.2 CABLING
The cabling and earth wires connected to the
filter input should always be run separately,
with a minimum clearance of 300 mm
between them and all other cables or sensi-
tive equipment (as shown in Figure 11). The
input cable and earth wire will carry the tran-
sient energy, while the "protected" output
cable can be considered to be a "clean
filtered" supply.
By separating these cables, any incoming
transients will not be induced from the input
cables onto nearby "clean" cables. This clear-
ance will reduce the possibility of arc-over
from input to output cables. Where cables
need to run closer together due to space
restrictions, input and output cables should
cross at right angles and not be installed
parallel to each other. Cabling should be
sized in accordance with all relevant wiring
standards to ensure that the full load current
can be safely supplied. All cabling or busbars
connected to the protection equipment
should be securely anchored to prevent
undue stress being applied to the
input/output terminals.
Input and output terminal requirements are
detailed in Table 2.
Cable terminal torque requirements are
detailed in Table 3.
• Cable glands (of an appropriate design)
must be used for all input and output
cables to preserve the IP rating of the
40A - 200A TSG SRFs.
• To protect input and output cabling
insulation from sharp edges around the
cable entry knockouts, suitable cable
glands or grommets must be installed.
An alternative is to extend the cable
conduit through the knockout.
