Trunk and Drop Cabling with Taps December 2000

• For each drop cable, provide a service loop to allow the connector to

be connected and disconnected at the network node device without

any strain on the cable. A service loop of 6 in. (152 mm) minimum

radius is adequate for most installations.

• Install cable ties or clamps on each trunk cable segment as required

for strain relief, to prevent the cable from pulling on the tap.

• Install cable ties or clamps on each drop cable as required for strain

relief, to prevent the cable from pulling on the tap or node device

connector.

• Use additional ties or clamps as required to secure each cable to

prevent flexing or other damage in areas of mechanical motion devices

and traffic.

Mounting the Tap

Mount each tap at a location near its node device, preferably outside the

drive controller enclosure. The tap must be near enough to the node

device to allow the drop cable to reach the node device with a service

loop. See Figure 16 for drop cable routing.

The location must also be accessible for installing the trunk and drop

cables and for future maintenance. Figure 17 shows the tap’s outer and

mounting dimensions.
