Note
A customer-supplied external circuit breaker should be separately mounted to the input power supply lines.
1. Install a customer-supplied 2-inch (50.8 mm) conduit elbow in the concrete pad for external wiring routing into the
bottom mounting hub of the cabinet.
Note
Depth of the concrete foundation should be a minimum of 6 in. (152.4 mm) below frost line.
2. Install a customer-supplied 2-inch (50.8 mm) threaded coupling on the threaded end of the conduit elbow.
Note
Make sure the coupling is installed level and square with the concrete pad. Level by adjusting slip-fitters on pipe
extending downward from cabinet. An alternate method is to use a 6 1/4-inch (158.75 mm) base flange, and bolt
the flange to the concrete pad over the conduit elbow flush with top of pad.
When the base flange is used, make sure the flange can be installed level with the concrete pad. Use shims on the
flange if further leveling of unit is required. Make sure the conduit is flush with the top of the concrete pad.
3. Coat the threaded end of frangible coupling with silicone grease and thread onto base flange or conduit elbow coupling.
4. Loosen the hex head screws in the mounting hub and mount cabinet on frangible coupling.
5. Place a level on top of the cabinet. Level by adjusting slip-fitters on the pipe extending downward from the cabinet.
6. Tighten the hex head screws in the mounting hub against the frangible coupling when the cabinet is level.
Note
To properly aim the light unit, each cabinet must be level and parallel to the runway centerline when the cabinets
are installed.
7. Tighten the hex head screws against the hub.
Series Circuit Connection Installation
•
For L-849I series circuit powered REILS, install a L-867 base can to house the L-830 or L-831 isolation transformer.
See
Figure 17 for details.
For L-849V voltage powered REILS with current sensing
•
For L-849V voltage powered REILS that use current sensing for remote control, install a L-867 base can next to the
Primary enclosure.
See
