D. Electrical Connections (see figure 2)
The Model 371DST comes assembled from the factory with three color-coded leads for wiring to a
junction box. If desired, the factory leads can be removed and the supply connections can be directly
made to the terminal block located on the backside of the mounting bracket as described below.
To avoid electrical shock hazards, do not connect to supply circuit when power is applied.
1. Disassemble the light as follows:
a. Remove dome assembly by grasping the die-cast ring attached to the dome and turning it
counter-clockwise.
b. Remove three #10 hex head screws that secure strobe-spinning assembly to housing.
c. Remove strobe-spinning assembly.
d. If desired, remove the factory field wiring leads from the terminal block.
2. If conduit side entry is to be used, attach either Myers STNTB-2 or T&B H075-TBH 3/4”
N.P.T. conduit hub with 3/4” N.P.T. close nipple (all user-supplied) to housing and tighten securely.
When using side entry, the bottom 1” NPT conduit entry must be plugged with a UL listed threaded
plug (user-supplied).
3. Route supply wires (10 AWG to 16 AWG) into the housing.
