Wiring
The GFCI is installed in series with the main circuit. Connection of the main circuit conductors
varies based on quantity of conductors and system voltage. In general, the following steps
must be taken:
• All active conductors, including the neutral, must be
brought into the device and landed on the provided
terminals.
• All active conductors are then brought out from the
load side of the contactor to the load / remaining
branch of the circuit.
• The ground wire is landed on the ground terminal
on the backplate, and brought out the load side.
The ground wire is NOT routed through the current
transformer.

Installation
Mounting - NEMA 4X Polycarbonate Enclosure
The standard enclosure for LifeGuard series GFCIs is a NEMA 4X polycarbonate enclosure. The
enclosure includes mounting feet and separate instructions on wall-mounting the enclosure.
Refer to these instructions for more infromation. Refer to gure 1 below for dimensions.
!DANGER
• Disconnect all power before servicing.
• Observe all local, state, and national
codes, standards, and regulations.

If the LifeGuard GFCI was purchased without an enclosure (backplate only), consult the follow-
ing section “Wiring,” as well as the section “Backplate Only Models” on the reverse side of this
document for additional mounting and wiring requirements.
Use of This Document
This installation guide applies to the special Compact version of the LifeGuard GFCI which
meets the following requirements:
• 20 A rated load current
• Line-to-line voltage of 240 VAC or below
• Have option“6” or “20”for trip level and utilize the RCMA426H ground fault module
• Push button type front only (no digital display option)
For standard LifeGuard GFCI models, consult document NAE108011. For LifeGuard GFCIs with
digital display option, consult document NAE1088440. For all models, consult the full Life-
Guard GFCI user manual, document NAE1085011.

Installation Bulletin / Reference Guide
Use - Enclosure Front
Additional Requirements - Backplate Only Models
This section only applies to LifeGuard models purchased without an enclosure and on the
backplate only. Refer to instructions below for additional requirements for installation and
wiring. Backplate-only models are typically integrated into existing cabinets or machinery.
Mounting - Backplate Only
Refer to Figure 3 below for dimensions. The GFCI must be mounted in a location sucient to
protect live electrical equipment. Use four (4) #10 screws for mounting. The vertical clearance
of the backplate is 6” for models less than 100 A, and 8” for 100 A models.
Figure 4 - Standard front of LifeGuard enclosure
1. POWER LED / RESET button: Illuminates
when the GFCI has received power and
the device has not tripped / Resets the
GFCI if faults have been cleared (mo-
muntary push).
2. TRIPPED LED / TEST button: Illuminates
when the GFCI has tripped / Performs a
functional test of the GFCI (hold for at
least 2 seconds).
3. E-stop button (OPTIONAL - OPTION “S”
ONLY): Pushing in this button will not
allow the GFCI to start regardless of
ground fault condition. This is only in-
cluded in models which end in “-S.”

Wiring - Control Wiring
Follow the standard wiring instructions on the reverse side of this document. Additionally,
backplate-only models include a terminal strip for wiring external connections. These connec-
tions must be wired for proper operation. Refer to gure 4 below. LifeGuard models purchased
with an enclosure come pre-wired and do not require any of the following connections. Con-
tacts denoted with an asterisk (*) are provided with 120 VAC from the backplate.

Operation
Apply power to the GFCI
To apply power, close the circuit breaker / disconnect on the line side of the GFCI. If there are no
ground faults present on the system, the green ON LED will illuminate.
Test procedure
• Push the TEST button on the front of the enclosure for at least 2 seconds.
• The GFCI will trip, the green ON LED will go out, and the red TRIPPED LED will illuminate.
Power to any connected loads will be interrupted.
• An internal self-test will initiate which takes approximately ten (10) seconds.
• Push the RESET button on the front of the enclosure for at least one (1) second.
• The GFCI will reset, the red TRIPPED LED will go out, and the green ON LED will illuminate.
Power will then be restored to the load side of the GFCI.
Field Adjustments
Compact LifeGuard GFCIs utilize ground fault modules which are not eld-adjustable. Models
are either xed at a 6 mA or 20 mA trip level, depending on option.
