Installation and Maintenance Instructions
Model 371LED-120 Rotating Light
Surface Mounting the Light
To mount the light on a flat surface:
1.
Using the
gasket as a template, scribe four drill-position
marks on the mounting surface (Figure 2).
2.
Drill a 9/32-inch (7.1 mm) diameter hole at each of the
outside drill-position marks for mounting.
3.
Drill or punch a 1-3/8 inch (34.9 mm) diameter hole at the
center drill-position mark for the wire entry.
4.
Attach a suitable 1-inch NPT hub or connector to conduit
entrance in bottom of light. For Type 4X/IP66 applications,
the hub or connector must be suitably rated (Myers
®
STTTB-2 or T&B
®
H100-TB hubs are recommended.)
5.
Set the light on the gasket and attach it to the mounting
surface with the provided 1/4-inch screws and washers.

For information on making the electrical connections, see
page 11.
Installing the Optional 22.5-Degree Reflector
The light is shipped from the factory with the standard reflector
that creates a horizontal lightbeam that is 90 degrees from the
vertical orientation. An optional reflector is available that reflects
the light beam at 22.5 degrees from the vertical orientation (see
Figure 1 on page 7 and “Table 4 Accessories” on page 15).
To replace the standard reflector with the 22.5-degree reflector:
1.
Disconnect power to the light.
2.
See Figure 3 on page 10. Remove the dome assembly by
grasping the die-cast ring attached to the dome and turning it
counter-clockwise.
3.
Loosen the two Phillips screws that retain the reflector.
