STEP 3
Push a length of copper wire (No. 14 AWG (2,5mm2) or equivalent) through one of the grounding tabs on the bushing insert.
Make a small loop and twist tight, taking care not to damage the grounding tab. Connect free end of electrostatic grounding
wire to the system ground using a suitable connector.
The electrostatic grounding wire should be installed in such a manner so as not to contact the bushing interface or adjacent
bushing interfaces or interfere with the placement of accessories on nearby parking stands.
This step provides assurance that the insulation shield on the bushing insert is grounded.

Thoroughly wipe the bushing interface clean of any contaminants and lubricate with the supplied lubricant. Install the mating
products to the bushing insert following the instructions supplied with the mating products. If the bushing insert is not to be
immediately mated with an elbow connector, insulated cap or grounding elbow connector, replace the shipping
cover. Do not energize or submerge the apparatus with the shipping cover on the bushing insert. This is a protective
