INDICATOR FLASH RATES (L1, L2, L3, GND)
5. For Delta configured power, connect the 1 bar, 2 bar & 3 bar black wires to L1, L2, & L3
respectively (Fig. 1) on the fused or disconnect side of the 3-Phase line voltage. The
Green/Yellow stripe (Grn/Yel) wire
be connected to Earth Ground. (Fig. 3)
6. Wye configured power with grounded Neutral is connected the same as for Delta in step 5.
The Grn/Yel wire
connect to the neutral but to non-current carrying Earth
Ground.
The neutral will not be monitored for voltage by the Detector, only Phase-to-Phase
and Phase-to-Ground voltage will be detected. To include neutral monitoring go to step 7.
7. Ungrounded or high resistance Wye configured power requires (2) additional units to include
all possible voltages the Neutral line introduces. Wire as shown in Figure 2.
8. First disconnect all equipment that may introduce a hazard and
notify personnel before powering the panel!
With normal voltage applied, the L1, L2, and L3 indicator pairs
will flash at rates according to the applied voltage (See table below).
