Bender LifeGuard Series Reference Manual

This document is intended as a reference guide for installing and using a BENDER LifeGuard series
Ground Fault Circuit Interrupter (GFCI) with digital display option. This document includes installa-
tion, setup, and usage instructions. For complete instructions, including setup, use, and troubleshoot-
ing, refer to LifeGuard user manual, document NAE1085011.
Only qualified maintenance personnel shall operate or service this equipment. These instructions
should not be viewed as sufficient for those who are not otherwise qualified to operate or service this
equipment. This document is intended to provide accurate information only. No responsibility is as-
sumed by BENDER for any consequences arising from use of this document.
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.
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.

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.
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.
