STARTING THE INSTALLATION
It is recommended that the installer starts at a junction location and attach tray sections from that point out. The hanging or mounting hardware should be secured to the building structure first, spaced at 5 ft.intervals.
CONNECTING STRAIGHT AND JUNCTION SECTIONS
1. Inspect all connection loops and interconnection points of each cable tray, elevation change and junction to insure the contact surfaces (both top and bottom) are free from paint, dirt, or other material that may hinder conductivity or proper connectivity
2. Align each adjacent cable tray and/or junctions together so the galvanized portion of each connecting loop overlaps the outside surface of the galvanized interconnect point of each tray section side wall. Butt the sections together and secure using a CM68 carriage bolt and CM67 flange nut at each connection point.
3. All interconnection points must be secured with a carriage head bolt and flange nut oriented.
4. The heads of all carriage bolts must be located inside of the cable trays, drops or junctions to prevent damage to the cable insulation.
5. All nuts must be tightened securely using a 1/2″ wrench or similar tool to insure good equipment ground conductivity.
6. It is recommended cable tray sections be secured to the support or mounting brackets at random intervals using a 4 inch center support (CM54-04), or a standard cable clamp. If the support location is at the connection loop area, use a carriage bolt and flange nut to secure it to the tray.
7. When bridging a gap less than 12 inches between two adjacent tray sections that are less than 12 inches wide, use two CM58 Extension Loops to connect tray side sections and two CM58 Extension Loops to connect the bottom of the adjacent tray. The Extension Loops are to be secured to the connection loop of each tray with a carriage bolt (CM68) and nut (CM67). Tray sections 12 inches or wider require three Extension Loops to connect the tray bottom.
