These include arrangement drawings(front, end, and plan view), connection diagrams,and schedule of equipment. Any material exteriorto the equipment that may be required to meet anylocal codes is not furnished.
I N S TA L L AT I O N I N S T R U C T I O N S5Storage precautionsDANGERBefore storing, unpack sufficiently to check thebusway for possible concealed damage resultingfrom shipping and handling. If damage hasoccurred, notify the shipper immediately. If thebusway is free of damage, restore the packing untilready for installation.Store indoors in a clean, dry area, preferably closeto the installation points.Protect the busway from mechanical damage andany contact with or exposure to corrosive fumes,liquids, salts, or concrete.WARNINGFailure to store and protect the busway properlycan cause serious damage and will void theCAUTIONwarranty.NOTICESAFETYINSTRUCTIONSNOTICE: No busway, includingoutdoor rated, is weatherproof untilcompletely and properly installed

Contact surfaces mustbe clean. Do NOT attempt to polish tarnishedcontact surfaces. Check that joint insulators are not damaged orcracked and are firmly in place. Megaohm test the piece before installation.

Apply the gasket to the clean surface of theswitchboard using the gasket locator dimplesshown in Figure 4.Rear of switchboardLocation dimplesFront of switchboardHorizontal gasketVertical gasket (7.75")—04—03Gasket locator dimples for N3R construction Cut the supplied gasket into (4) total strips – (2)shorter to be applied in the vertical direction and(2) longer to be applied in the horizontal direction(Figure 4) The length of the horizontal (longer) pieces ofgasket will vary depending on the ReliaGearbusway material and amperage rating. Cut thehorizontal strips per Table 1. The vertical stripsmust always be cut to 7.75”7.75"NOTICESAFETYINSTRUCTIONSNOTICE: The phase side of theintegrated busway connection insidethe switchboard will always befacing the front of the switchboard.
