1. DESCRIPTION
The EL3100 is a self-powered ground-fault and phase-
voltage indication system for three-phase systems. The
EL3100 meets the National Electrical Code requirements
for ground detectors for ungrounded alternating-current
systems as defined in NEC 250.21. It also meets the
Canadian Electrical Code requirements for ungrounded
alternating-current systems in accordance with
CEC 10-106(2).
Voltage connections are provided on the EL3100 for
208-, 240-, 480-, and 600-V systems. Three green LED’s
on the EL3100 indicate the presence of phase-to-ground
voltage and one red LED indicates a ground fault. The
phase LED intensity is a function of line-to-ground voltage
providing visual indication of phase balance.
There are cases when one of the three phase indicators
is off but no ground fault is indicated. This occurs on an
ungrounded system when there is a phase loss. Ground-
fault indication is still enabled and will be activated when
either of the energized phases develops a ground fault.
The EL3100 can operate stand-alone or with up to five
remote LED indicators. High-intensity 16-mm IP67 LED
lamps are available in red and green colors. LED indicators
and wiring operate in low-voltage mode.
A solid-state relay output provides indication of a
ground fault. The output relay is closed when the three-
phase neutral voltage shifts as the result of ground leakage.
2. FEATURES
Direct connection to EL3100 for voltages up to
600 Vac line-to-line
Provides faulted-phase indication for resistance-
grounded and ungrounded systems
Provides phase-voltage indication for resistance-
grounded and ungrounded systems
The EL3100 can be used stand-alone or with low-
voltage remote LED’s
oSolid-state (100 mA, 120 Vac/Vdc) output relay
oThree green phase-voltage LED’s
oOne red ground-fault LED
oUp to five remote LED’s can be connected
3. REMOTE INDICATION
Terminals 10 through 15 are used for remote LED
indication. High-intensity LED’s with no internal resistors
are required. See Section 7 for ordering information. Fig.
2 illustrates a remote LED application where all LED’s are
used.
There are five remote LED outputs for phase-voltage
indication, no-ground-fault indication, and ground-fault
indication. Connect optional remote LED’s to terminals
DA, DB, and DC (12, 11, and 10) for phase-voltage
indication. The intensity of these LED’s is proportional to
phase-to-ground voltage. A ground fault or phase loss is
indicated when one LED is off while the other two are on.
A remote LED connected to terminal DG (13) provides no-
ground-fault indication. This LED is on when there is no
ground fault and is off when the three-phase-neutral
voltage shifts from ground potential as the result of a
ground fault (or if the system is de-energized). A remote
LED connected to terminal DR (14) is on when a ground
fault is present and off when no ground fault is present (or
the system is de-energized). Terminal DN (15) is the LED
common terminal.
NOTE: Unused LED outputs must be left unconnected.
4. OUTPUT CONTACT
A solid-state normally open ground-fault-indication
relay output is at terminals 16 and 17. The output relay is
closed when the three-phase neutral shifts more than
20 Vac with respect to ground for the “L” voltage inputs
and 40 Vac with respect to ground for the “H” voltage
inputs.
NOTE: The relay output has a rating of 100 mA at
120 Vac/Vdc and has a 35-Ωclosed resistance.
5. INSTALLATION
Outline and mounting details of the EL3100 are shown
in Fig. 1. For 208- or 240-Vac systems use terminals
AL (7), BL (8), and CL (9). For systems above 240 Vac
and up to 600 Vac, use terminals AH (1), BH (3), and
CH (5). Connect bonding terminal (G) to ground. See Fig.
2. Terminals 2, 4, and 6 are not used.
NOTE: Bonding terminal (G) must be connected to ground
for correct fault indication and to ensure that fault potential
is not transferred to the display.
Outline and mounting details for the remote LED’s are
shown in Fig. 3. Cable length should be limited to
10 m (33 ft). The recommended cable is 22 - 18 AWG (0.33
to 0.82 mm2) wire. Use shielded cable for cable lengths
exceeding 2 m (6 ft). When shielded cable is used, connect
cable shield to terminal SH (18) at the EL3100 only.
