NOTE

Refer to Splice Module installation instructions for the length required inside the cabinet. Ensure sufficient sheathed cable exists at the top of the sealing grommet to install shield connectors.

i.Using a wrench to hold the sealing grommet steady, use a second wrench to tighten the compression nut until the compression skirt creates a weathertight seal around the cable.

II.SHIELDING

On non-stubbed cabinet installations the shield and braid must be connected to the ground buss as described in this procedure. Refer to Figure 12 for views of the connector components, cable, and assembly sequence. Entry cables have an outer insulator, a shield sheath, and a core wrap protecting the inner wire bundle, see View A. The shield sheath must connect to ground with the supplied connectors and ground braid.

The connectors and ground braid are temporarily attached at the factory for cabinet shipment, remove the connectors from the braid for this procedure.

CAUTION

Ensure wire insulation is not damaged during shield connection.

a.From where the wire bundle exits the cable, remove about 3/4 inch of insulation and shield but leaving the protective core wrap intact. See view B for steps a and b.

b.On the side opposite from where the shield connector will be placed, make a one inch slice through the insulator and the shield but not the core wrap. This eases the insertion of the connector.

c.Opposite the slice, insert the connector bottom into the cable between the shield and the core wrap until it reaches the small stop tabs. See view C for steps c and d.

d.Tap the cable in the area of the leading edge of the connector to set the contact teeth into the shield

e.Slide the connector top over the stud so it sandwiches the shield and insulator. Install the

first nut and tighten until the connector securely grips the shield and insulator. See view D.

f.Install the ground braid over the stud followed by the second nut and tighten securely. See view E. Repeat this process for the remaining cable.

g.Ensure the trailing end of the ground braid is securely connected to the ground buss.
