1. Verifying Proper Operation: First disconnect all equipment
that may introduce a hazard and notify personnel before
powering the panel!
2) TURN POWER ON. With normal voltage applied, the L1, L2,
and L3 indicator pairs will illuminate at rates according to the
applied voltage (See table below).
3) GND Indicator Pair Operation: For isolated Delta or
3-Phase WYE applications, it is normal for the “GND” indicator
pairs not to illuminate unless a phase is lost producing an
unbalanced condition. This peculiarity results when the Phase-
to-Phase voltages are balanced resulting in no current to
a Neutral connection. The R-3W-SR indicators are current
driven; therefore, no net current in the R-3W-SR ground line
(connected to Neutral) will cause the “GND” indicators to not
illuminate. A leakage resistance path from any phase-to-ground
from 2-7 Meg ohms producing a corresponding current from
7-67 μA in the “GND” wire is adequate for the “GND” indicators
to ash..
To complete proper installation, verify grounding of the GND lead-
wire. Under normal operation, the power system determines if
GND LEDs illuminate.
Proceed to GND verication steps below.
1) Apply power to the R-XXX, if the GND LEDs do not illuminate,
proceed to step 2.)
2) Remove power and re-establish an electrical safe work
condition to allow one phase lead-wire to be disconnected from
its source by either disconnecting wire or pull a fuse.
3) Re-apply power and verify that the GND LEDs now illuminate
to insure a proper ground connection.
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 nal
installation.
2. To meet UL TYPE 4, 4X, 12 or 13 sealing requirements, mount
on a at surface of an enclosure qualifying for a respective
TYPE or NEMA rating or equivalent elevated ambient rating.
3. Locate the unit in visual proximity to the control panel ON/OFF
disconnect and within wiring distance to incoming Main Lines
and Earth Ground. Verify there is no interference with the free
operation of the ON/OFF disconnect mechanism.
4. For Standard Mount, refer to knock-out pattern on the
following pages and Control Drawing No. 212 for assembly.
For Low Prole Mount with R-3W-SR-BZL kit, refer to knock-
out pattern on the following pages and Control Drawing No. 213
for assembly.
5. For Delta congured 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 MUST be connected to Earth Ground. (Fig.
3)
6. Wye congured power with grounded Neutral is connected
the same as for Delta in step 5. 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 7.
7. Ungrounded or high resistance Wye congured power requires
(2) additional units to include all possible voltages the Neutral
line introduces. Wire as shown in Figure 2.
