Equipment needed:
Digital Volt Meter with 600V AC or DC rated input minimum, 10M ohm input impedance and CAT III & IV. A pair of insulated test probes with .080" DIA. points.
Directions: Before and after each test, determine the volt meter is operating satisfactorily through verification of known AC & DC voltage sources. With the meter
switched to ACV and test leads in ACV meter jacks, a qualified person can insert probe points into any two of the (4) terminal posts {L1, L2, L3, GND}.
1. To validate normal powered conditions, AC voltage is observed for all six (6) post pair combination circuits {L1-L2, L1-L3, L2-L3, L1-GND, L2-GND, L3-GND}.
2. To check for zero electrical energy during shut off, verify sources of feedback or stored energy are first neutralized. With the meter and leads setup for ACV
measurement, verify the (6) post pair combination circuits above are de-energized. Change voltmeter and test leads for DCV measurement. Again verify the (6) post
pair combination circuits are also de-energized for DCV (stored energy).
With power removed, free dust and particles from front label and jack sockets with compressed air. Maintain a clean label by gently wiping with a clean damp cloth
while power is removed. Cleaning while powered is not recommended.
OPERATING INSTRUCTIONS
MAINTENANCE:
BEFORE OPENING A PANEL, TURN POWER OFF! SAFETY PROCEDURES STILL APPLY! Before working on an
electrical conductor, verify zero electrical energy with proper voltage testing instrument and the proper procedure as
per NFPA 70E 120.1(5), 120.2 (F)(2)(f)(1-6), OSHA 1910.333(b)(2)(iv)(B)."
AVANT D'OUVRIR UN PANNEAU ÉLECTRIQUE, COUPER L'ALIMENTATION! LES PROCÉDURES DE SÉCURITÉ S'APPLIQUENT
TOUJOURS! Avant d'effectuer des travaux sur un conducteur électrique, vérifier que le courant est coupé à l'aide d'un instrument de mesure de
tension approprié en suivant la procédure adéquate, selon les normes de la NFPA (National Fire Protection Association) 70E 120.1(5), 120.2
(F)(2)(f)(1-6), de l'OSHA (Occupational Safety and Health Administration) 1910.333(b)(2)(iv)(B).

CAUTIONCAUTION
• ALWAYS connect the GRN/YEL (GND) conductor to earth ground.
• Location of device and internal hardware/wiring MUST allow free operation of ON/OFF disconnect mean. For indoor use only.
• Means of anti-rotation is required (see knock-out for one or more tab locations).
• The O-ring material is FVMQ uorosilicone. Please refer to a Chemical Compatibility chart for your application(s).
• Do not operate above 750V 3or 1000V ,@ 55°C ambient or >2000m altitude or >80% RH.
• If this product is used in a manner not herein prescribed, the protection provided may be impaired.
• PESD conductors must be protected over their entire length from damage to conductor insulation that would cause a short circuit or ground fault to
occur. Please refer to the protection methods outlined in Paragraphs 29.4.2 and 29.4.4. b) of UL 508A.

Use of an Overcurrent Protection Device or Fuse is “NOT RECOMMENDED“ when installing these devices in safety applications
for verifying both voltage presence and voltage absence condition. A blown fuse or a tripped circuit breaker connected in line
with this device could potentially lead to a false negative indication of voltage which is otherwise present. This device has been tested as equivalent
to overcurrent protection for the application of tap conductor requirements.
R-3W-SR Voltage Indicators are used to visually notify the presence of both AC & DC voltages
(stored energy). This product is intended to be used on Three Phase, 4-wire AC applications.
It can also be used in Single Phase, 3-wire AC applications.
Cancer - Reproductive Harm. This product can expose you to chemicals which are known to the state of California to cause
cancer, birth defects or other reproductive harm. For more information, go to: www.P65Warnings.ca.gov

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 verication 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 Prole 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 congured 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 congured 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 congured power requires
(2) additional units to include all possible voltages the Neutral
line introduces. Wire as shown in Figure 2.

4) Complete installation by removing power and reconnecting the
phase lead-wire or fuse and reapply power and re-verify that L1,
L2, & L3 LEDs illuminate.
MAINTENANCE
1) For O-Ring inspection, follow the respective Control drawing
directions pages 7 & 8.
2) For Cleaning the front black label or the information sticker, use
only clean water and a soft cloth.
BEFORE OPENING A PANEL, TURN POWER
OFF! (Steps 1-8 must rst verify proper operation
of indicators.) SAFETY PROCEDURES STILL APPLY: Before working
on an electrical conductor, verify zero electrical energy with proper
voltage testing instrument and the proper procedure as per NFPA 70E
