• Insert the ceiling rod up through the ceiling casting until the hole in the ceiling rod becomes
visible (see figure 6). Insert the dowel pin into the hole in the ceiling rod and lower the rod in the
ceiling casting, making sure the pin is seated securely in the indentation on the ceiling casting.
Securely tighten the two set-screws located in the casting.
Failure to install the dowel pin can cause the arm/head assembly to fall from the
ceiling causing serious injury and/or property damage.
Improper fastening of the ceiling casting can cause serious injury and/or property
damage. Make certain the installation is capable of supporting a load of at least 100 pounds
and an off center moment of 300 ft-lbs.
• Fasten the ceiling casting to the desired location using four
hex bolts or lag screws with washers (hardware not provided). This can be done by mounting
the casting to a suitable material that will function as a ground conductor, or a wire lead that
must be attached to the ground screw on the casting then routed to proper ground (see figure
5).
Note: The ceiling rod must be plumb. Shim the casting if necessary.
Note: The ceiling casting itself must be electrically grounded to maintain proper
grounding reliability.
If ceiling rod is not plumb, unwanted arm drifting may occur.
• Feed the wire harness through the ceiling rod extension and route to a junction box. Leave
sufficient wire to extend slightly beyond the bottom of the ceiling rod. Important: To achieve
proper grounding reliability, the green ground wire from the wire harness MUST be
properly fastened to the grounding screw located on the ceiling casting (see figure 5).
Make all electrical connections in compliance with all applicable electrical codes.
Failure to comply with local electrical codes can cause a shock hazard.
• Slide the casting cover up the rod over the casting. Similarly, slide the collar to the casting
cover, then tighten the set screw to hold the cover in place. Feed the wire harness through the
ceiling rod with the rod in the direction shown.
Do not install the extension arm with the light head attached. Installation with the light
head attached can cause damage to the light. Refer to the procedure for installing the head
to the arm after the bracket and arm are installed.
