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, through the current trans-
former, and landed on the line side of the contactor.
•
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 lug on the
backplate. 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 figure 1 below for dimensions.
! DANGER
• Disconnect all power before servicing.
• Observe all local, state, and national
codes, standards, and regulations.

For other enclosure types, refer to LifeGuard user manual, document NAE1085011.
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 digital display version (option “D”) of the LifeGuard
GFCI which meets the following requirements:
•
Uses door mounted MK1500-D remote (backplate only models have connections)
•
Uses “6” or “20” option (6 mA fixed or 20 mA fixed trip level)
For compact LifeGuard GFCI models, consult document NAE1088320. For standard LifeGuard
GFCIs with pushbutton front, consult document NAE1088011. For all models, consult the full
LifeGuard GFCI user manual, document NAE1085011.
