1. Follow all Local, State, and National Electrical Codes when
installing this equipment. Overcurrent protection is not
recommended. If device leads are either extended beyond
the supplied length or the device installation extends beyond
the enclosure where the leads are terminated, overcurrent
protection of the supply leads may be required by Local, State
or National Electric Codes. The installation of overcurrent
protection shall be in accordance with the requirements in the
NEC (NFPA 70) or end product standard(s) when used in final
installation. These instructions are able to be used for factory
and/or field installation.
2. Locate the unit in visual proximity to the control panel ON/OFF
disconnect and within wiring distance to incoming Main Lines
and Earth Ground. Mount the unit through a 30.5 mm knockout
hole on the three-phase control panel to be monitored. To meet
Type 12, 13, 4, or 4X sealing requirements, mount with supplied
cap on a clean flat surface or inside a Type 4 or 4X housing.

3. For Delta configured power, connect 1 bar, 2 bar & 3 bar
black wires to L1, L2 & L3 respectively (Fig. 2) on the fused or
disconnect side of the 3-Phase line voltage. The Green/Yellow
stripe (Grn/Yel) wire MUST be connected to Earth Ground.
(Fig. 2)
INSTALLATION INSTRUCTIONS
4. Wye configured power with grounded Neutral is connected
the same as for Delta in step 3. The Grn/Yel wire DOES NOT
connect to the neutral but to non-current carrying Earth Ground.
Caution: 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 5.
5. Ungrounded or high resistance Wye configured power requires
(2) additional units to include all possible voltages the Neutral
line introduces. Wire as shown in Fig 3.
6. For Single Phase configured power, connect Black & White
wires to L1 & N respectively (Fig. 6) on the fused or disconnect
side of the line voltage. The Green/Yellow stripe (Grn/Yel) wire
MUST be connected to Earth Ground. (Fig. 6)
7. With the PESD installed, wired, and the enclosure closed, verify
the power disconnect is OFF.
8. Using the proper test equipment: the voltmeter should be rated
for Cat III/1000V and Cat IV/600V. Test probes should be fully
insulated with .080" DIA points to insert into test point jacks.
9. For Three Phase Circuits: Follow all safety and lock-out/Tag-out
(LOTO) procedures. Set voltmeter to ACV, verify zero voltage
between (6) test point combinations {L1-L2, L1-L3, L2-L3, L1-
GND, L2-GND, L3-GND}, Switch meter to DCV. Repeat all (6)
measurements.
