| NOTICE |

Risk of loose cables
Lace and secure all cables. Cable restraint is required
on the line-side of the ArcBlok section.
Failure to follow these instructions can result in equipment damage.
|
Cable restraint is required on the line-side of the ArcBlok section. All cables must be laced and secured prior to installing the cable vault front cover.
-
Wrap cables using 1/2 in. (13 mm) diameter sisal rope or equivalent.
-
Lace the cables from all phases together in one bundle with a continuous length of rope.
-
Lacing requires two sets of looping groups: an entry loop group and a second loop group nearer to the ArcBlok.
-
Attach one end of the rope to on of the cables about 10 in. (254 mm) from the floor.
-
After attaching the rope, make a loop in it and pull the loop around the entire cable bundle from behind. Pull the loose end of the rope through the loop and continue to pull it until the rope is tight.
-
Make a second loop and pass behind the cables using the same procedure. Put the loose end of the rope through the loop and pull the loop tight. Repeat this step one additional time.
-
Start the second (upper) loop group by first pulling the rope around the cable bundle, then repeat the procedure described in step 6 for the upper loop group. The spacing between the upper and lower loop groups must be no more than 5 1/2 in. (139 mm). See Upper and Lower Loop Group Spacing.
Upper and Lower Loop Group Spacing
-
After the entire cable bundle has been laced, tie the end of the rope securely to the looping groups, then cut and tape the end to prevent fraying. Make sure the rope is not obstructing the cable vault front cover, fuse disconnect switch wiring, or ArcBlok Event Indicator plunger.
