Installation and Maintenance Instructions
Models 151XST and 151XST-S
SHOCK HAZARD—To avoid electrical shock hazards, do not
connect wires while power is applied.
EXPLOSION HAZARD—Do not disconnect the beacon while
the circuit is live or unless the area is known to be free of
ignitable concentrations. Keep the beacon tightly closed
when in operation.
REVERSE POLARITY/MISWIRING—Although the 151XST
is not polarity sensitive, it MAY BE DAMAGED by incorrect
electrical hookup. Damage will result if the voltage rating of
the particular model is exceeded.
NOTE:
Wiring must comply with the National Electrical Code
or Canadian Electrical Code and the local authority having
jurisdiction.
Wiring the AC Models
The AC models have two 24-inch leads, one black and one
white. To wire the AC beacon:
1.
Ensure that power is off.
2.
Remove the threaded dome assembly by twisting it
counterclockwise.
3.
Connect the black lead to the phase (hot) side of the power
source and the white lead to the common (neutral) side of
the AC power source.
4.
If required, the green screw in the housing is provided
for connection to an earth ground (Figure 3 on page 13).
To gain access to the screw, remove the power supply
assembly.
5.
Secure the dome to the base of the beacon.
